Desktop Sandbox for computer use
We are launching the E2B Desktop Sandbox. It's a secure virtual desktop powered by E2B and made specifically for LLM-powered computer use. Each E2B Sandbox is isolated from the others and can be customized with any dependencies you want.
We also added an example of computer use, using the E2B Desktop Sandbox.
December 4, 2024
SDK Reference
We published the SDK reference for the E2B CLI & Core SDK, Code Interpreter SDK, and Desktop Sandbox SDK.
To learn more, see the corresponding page in documentation.
October 28, 2024
Support for interactive charts
We added support for interactive charts. E2B now automatically detects charts when executing Python code with runCode()
in JavaScript or run_code()
in Python. The Python code must include Matplotlib charts.
E2B sends the data of the chart back to the client, so you can then use your favorite chart library and create custom interactive charts.
See corresponding docs page, or try interactive charts in the E2B Analyst app.

Faster sandboxes and custom CPU and RAM
Up to 5x faster sandboxes
We implemented huge pages - a feature that allows customers to use 2 MiB chunks of memory instead of 4 KiB chunks, which are the default.
Huge pages are now enabled by default in all newly created custom sandboxes. If a user has an existing custom sandbox, they must rebuild it by calling e2b build
in the directory with the e2b.toml
file.
Custom CPU And RAM
We allowed Pro users to customize the number of vCPUs and RAM size for the sandboxes. The sandbox compute now also has a dedicated page in our documentation.
Pro users can now choose:
1 - 8 vCPUs
128 MiB - 8 GiB RAM

E2B SDK
This week, we have for you an early access version of the E2B SDK.
The E2B REST API gives AI agents their own sandboxed cloud environment. Agents can use these environments to run code, terminal commands, long-running tasks like databases, start servers, and upload and download files.
You can run pip install e2b to get our SDK.
The E2B SDK is available in Python and we are finalizing a JavaScript/TypeScript version. See the Python SDK also in PyPi or go through the examples.
We recently tried out our API in the e2b plugin for ChatGPT which you can check out if you have developer access to ChatGPT plugins.
Next on our roadmap
Make the API generally available
Integrate the API and the protocol into popular agent-building frameworks
Contributors our welcome, so in case you are interested, just do a pull request on our GitHub, or discuss more info on our Discord.
August 4, 2023
ChatGPT plugin
The e2b ChatGPT Plugin gives your ChatGPT access to a full cloud environment that is sandboxed and running on e2b infrastructure.
We’ve built these cloud environments to be used specifically by AI Agents. With the plugin, you can accomplish for instance deploying websites, managing databases, executing shell commands, or installing programs via the terminal.
Try out the Plugin here and tell us how you liked it via Discord or by tagging @e2b_dev on Twitter. Contributors and beta testers are welcome.
Agent Protocol Update
We did an overhaul of the Agent Protocol repository. Main updates include:
Better communication of incentives, roadmap, and usage
RFC template
Better code examples
New JS SDK
New agent-protocol CLI to check compliance with the spec.
The protocol serves as a common interface for interacting with any agent. It is techstack-agnostic and open-source.
July 2, 2023
Agents in cloud
We're now a few months into building e2b, which means we will be sharing weekly updates. Here's some news we think you'll love in this release.
Get your own instance of smol developer
This week, we have launched a smol developer - your own personal junior developer which you can deploy via e2b. You can connect the developer with three simple steps.
Let us know how you like the smol developer.
June 16, 2023
Protocol and smol updates
Agent Protocol
We have made first steps in developing the Agent Protocol.
The protocol defines an interface for interacting with your agent. Adopting the protocol makes your agent automatically deployable to the e2b platform.
Our goal is to make this protocol open and usable in the whole agent field. This is a collaborative project. We're working on it with the most popular open-source agents, e.g., Auto-GPT, smol developer, or babyagi.
Objectives:
Common endpoints to communicate with an agent - "start", "step", "stop" for starters. More will come, especially around debugging, tracing, and monitoring
Tech-stack agnostic - no specific framework required - you can adopt this without using the rest of SDK
Great DX - easy to adopt and implement - no need to rewrite your existing agent
Open - any agent builder can implement this and instantly become compatible with any platform supporting this protocol
If you like the protocol, please appreciate the GitHub repo with a star. Contributors are welcome.
Smol Developer Update
With more than 1500 smol developer pull requests, we hit OpenAI API rate limits. We consequently added an option to pass your own OpenAI key in case e2b is hitting OpenAI's rate limits.
Additionally, you can now select which OpenAI model you want to use with smol developer when using your own OpenAI key. Try the updated smol developer here.
December 9, 2024
Desktop Sandbox for computer use
We are launching the E2B Desktop Sandbox. It's a secure virtual desktop powered by E2B and made specifically for LLM-powered computer use. Each E2B Sandbox is isolated from the others and can be customized with any dependencies you want.
We also added an example of computer use, using the E2B Desktop Sandbox.
December 4, 2024
SDK Reference
We published the SDK reference for the E2B CLI & Core SDK, Code Interpreter SDK, and Desktop Sandbox SDK.
To learn more, see the corresponding page in documentation.
October 28, 2024
Support for interactive charts
We added support for interactive charts. E2B now automatically detects charts when executing Python code with runCode()
in JavaScript or run_code()
in Python. The Python code must include Matplotlib charts.
E2B sends the data of the chart back to the client, so you can then use your favorite chart library and create custom interactive charts.
See corresponding docs page, or try interactive charts in the E2B Analyst app.

Cloud playgrounds for AI copilots
This week we launched AI Playgrounds, supporting Python and JS/TS.
It is a sandboxed cloud environment where an AI agent or copilot can freely run code, use a filesystem, use a headless browser, and more.
Try the AI playgrounds here: https://e2b.dev/docs.
Every playground has its own URL, which allows your agent for example to start a web app. AI playgrounds are especially useful for coding copilots and agents. They can easily run linters, formatters, or debug code and feed all this information back to LLM to make the next iteration better.
Quality of life improvements
An API key is now required for our SDK (get your API key here)
Added timeouts to asynchronous methods in our SDK
Improved Python SDK debug logging

We hosted a community event in Prague where local startups talked about developer tools and AI.
August 18, 2023
Documentation & bug fixes in SDK
We released new documentation for the E2B SDK that helps you with getting started.
With a single line of our SDK, you can give your AI agent a sandboxed cloud environment where your agent can do any of the following (and more!):
Run any code
Run any terminal command
Install dependencies and programs
Use filesystem
Upload and download files
Access the internet
Start a web server that's accessible from the internet
Clone git repositories
Start any process (even long-running such as a database)
The new docs help you with installation and basic usage and examples are to be added soon. We have fixed reliability-related issues in the SDK.
We’ve been iterating with our early users and fixed a bunch of critical bugs.
If you want early access to the SDK, join our Discord and send us a message!
Agent Protocol Documentation
We put the Agent Protocol on a dedicated website with a nice domain and proper documentation.
The documentation goes deeper into the incentives of the protocol, guides for adoption, and the details of how the protocol works.
Discuss the updates on our Discord, and if you want to appreciate our work, star our repositories on GitHub.
August 11, 2023
E2B SDK
This week, we have for you an early access version of the E2B SDK.
The E2B REST API gives AI agents their own sandboxed cloud environment. Agents can use these environments to run code, terminal commands, long-running tasks like databases, start servers, and upload and download files.
You can run pip install e2b to get our SDK.
The E2B SDK is available in Python and we are finalizing a JavaScript/TypeScript version. See the Python SDK also in PyPi or go through the examples.
We recently tried out our API in the e2b plugin for ChatGPT which you can check out if you have developer access to ChatGPT plugins.
Next on our roadmap
Make the API generally available
Integrate the API and the protocol into popular agent-building frameworks
Contributors our welcome, so in case you are interested, just do a pull request on our GitHub, or discuss more info on our Discord.
August 4, 2023
ChatGPT plugin
The e2b ChatGPT Plugin gives your ChatGPT access to a full cloud environment that is sandboxed and running on e2b infrastructure.
We’ve built these cloud environments to be used specifically by AI Agents. With the plugin, you can accomplish for instance deploying websites, managing databases, executing shell commands, or installing programs via the terminal.
Try out the Plugin here and tell us how you liked it via Discord or by tagging @e2b_dev on Twitter. Contributors and beta testers are welcome.
Agent Protocol Update
We did an overhaul of the Agent Protocol repository. Main updates include:
Better communication of incentives, roadmap, and usage
RFC template
Better code examples
New JS SDK
New agent-protocol CLI to check compliance with the spec.
The protocol serves as a common interface for interacting with any agent. It is techstack-agnostic and open-source.
July 2, 2023
Agents in cloud
We're now a few months into building e2b, which means we will be sharing weekly updates. Here's some news we think you'll love in this release.
Get your own instance of smol developer
This week, we have launched a smol developer - your own personal junior developer which you can deploy via e2b. You can connect the developer with three simple steps.
Let us know how you like the smol developer.
June 16, 2023
Protocol and smol updates
Agent Protocol
We have made first steps in developing the Agent Protocol.
The protocol defines an interface for interacting with your agent. Adopting the protocol makes your agent automatically deployable to the e2b platform.
Our goal is to make this protocol open and usable in the whole agent field. This is a collaborative project. We're working on it with the most popular open-source agents, e.g., Auto-GPT, smol developer, or babyagi.
Objectives:
Common endpoints to communicate with an agent - "start", "step", "stop" for starters. More will come, especially around debugging, tracing, and monitoring
Tech-stack agnostic - no specific framework required - you can adopt this without using the rest of SDK
Great DX - easy to adopt and implement - no need to rewrite your existing agent
Open - any agent builder can implement this and instantly become compatible with any platform supporting this protocol
If you like the protocol, please appreciate the GitHub repo with a star. Contributors are welcome.
Smol Developer Update
With more than 1500 smol developer pull requests, we hit OpenAI API rate limits. We consequently added an option to pass your own OpenAI key in case e2b is hitting OpenAI's rate limits.
Additionally, you can now select which OpenAI model you want to use with smol developer when using your own OpenAI key. Try the updated smol developer here.
December 9, 2024
Desktop Sandbox for computer use
We are launching the E2B Desktop Sandbox. It's a secure virtual desktop powered by E2B and made specifically for LLM-powered computer use. Each E2B Sandbox is isolated from the others and can be customized with any dependencies you want.
We also added an example of computer use, using the E2B Desktop Sandbox.
December 4, 2024
SDK Reference
We published the SDK reference for the E2B CLI & Core SDK, Code Interpreter SDK, and Desktop Sandbox SDK.
To learn more, see the corresponding page in documentation.
October 28, 2024
Support for interactive charts
We added support for interactive charts. E2B now automatically detects charts when executing Python code with runCode()
in JavaScript or run_code()
in Python. The Python code must include Matplotlib charts.
E2B sends the data of the chart back to the client, so you can then use your favorite chart library and create custom interactive charts.
See corresponding docs page, or try interactive charts in the E2B Analyst app.

Faster sandboxes and custom CPU and RAM
Up to 5x faster sandboxes
We implemented huge pages - a feature that allows customers to use 2 MiB chunks of memory instead of 4 KiB chunks, which are the default.
Huge pages are now enabled by default in all newly created custom sandboxes. If a user has an existing custom sandbox, they must rebuild it by calling e2b build
in the directory with the e2b.toml
file.
Custom CPU And RAM
We allowed Pro users to customize the number of vCPUs and RAM size for the sandboxes. The sandbox compute now also has a dedicated page in our documentation.

LLM Sandbox is an isolated cloud environment for LLMs with support for long-running sessions.
You can customize sandboxes by creating a Sandbox Template, which is just a simple Dockerfile. This way, you can preinstall any needed libraries and packages, or prepare any files you need. Then you can simply control your Custom Sandbox with the E2B SDK.

LangChain Integration of Data Analysis Sandbox
This week, we announced the official E2B integration into LangChain and created a guide for trying out the E2B Data Analysis Sandbox with LangChain.
LangChain integration
E2B is now available as a tool on LangChain. The E2B LLM Sandbox is ideal for building your own AI Data Analysts and Code Interpreters.
A big advantage of the E2B Sandbox is a safe code execution - allowing for example installing packages dynamically, generating charts, or file upload & download.
Bug fixes
Fix SDK browser compatibility
Fix installing system packages inside Sandbox
Guides and examples
We wrote a tutorial for using E2B with LangChain to build your own AI data analyst.
We put together more examples of using E2B, which are now shared within the E2B Discord community.

Week #12
This week, we fixed various bugs in our SDK and worked on our infrastructure.
New design and communication
We made our docs a bit nicer and better structured. See how to get started with E2B, a useful step-by-step example, or an overview of the sandbox API. Check out our updated landing page. How do you like the new E2B logo?
Read about AI agents’ SDKs and frameworks
We shared an update on key topics of developing LLM agents and apps, covering for example security, privacy, memory management, frameworks, and developers' perspectives.
You can read it also on Medium or go through the frameworks and SDKs here.
October 13, 2023
Week #11
This week, we continued improving the E2B sandboxed environments and the Superagent integration of E2B. To try Superagent with E2B, create a Code interpreter API and then select it for your agent to use.
Additionally, we worked on the backend for building your custom Advanced Data Analysis/Code Interpreter, so stay tuned.
We published more content and expanded our blog to Medium. You can read the newest AutoGen tutorial for code-executing agents.
If you haven’t done it, try out our SDK here and tell us how you liked it via Discord or by tagging @e2b_dev on Twitter.

Superagent integration
E2B is now integrated into Superagent, meaning there is added support for a Code Execution feature. You can try it here.
This integration allows the AI agents to actually run code in a sandboxed environment, which helps for example with creating charts, doing requests, or analyzing files.
Join the Superagent Discord to stay updated and discuss your creations.
The code execution API in Superagent is still in its alpha version, as we are still working on improvements. We are very grateful for your feedback - let us know on Discord or contact our CEO at vasek@e2b.dev if you have any questions.
More E2B updates
We updated the E2B SDK - you can now set it on
stdout
, onstderr
, and on exit for the whole session.

A way to run LLM-generated code in sandboxed environments
This week, we released a simple way to run code generated by LLMs in the cloud:
Import e2b
Select runtime and pass LLM-generated code
Run code in a sandboxed environment
Get
stdout
andstderr
This way, developers of AI agents and apps don’t need to handle any infrastructure.
Read more in our documentation and let us know on Discord or contact our CEO at vasek@e2b.dev if you have any questions.

Week #08
This week we released a new version of our SDK, added examples of use cases, and continued working on the infrastructure and custom environments.
New methods
Write bytes
Writing bytes to a file in our playground allows you to upload binary files like images, audio files, or video files
Read bytes
Reading bytes from a file inside our playground allows you to download binary files like images, audio files, or video files
Added examples
We added runnable code snippets for the use case examples for AI agents to our documentation:
Executing code
Cloning GitHub repo & installing deps
Running shell commands
All use cases are available in Python and JS.

Week #07
We continued working on the E2B infrastructure and made several smaller improvements in our docs. If you want to stay in touch, please join our Discord, where we publish updates in real time.
Documentation updates
You can now run code samples in Python and JS directly in the docs
We added an example of how to run multiple processes with the SDK to our docs
We made our docs easier to use by highlighting relevant parts
New insights about agents
We closed the first part of our agent developers interview series with a conversation about building tools for LLM agents with the CEO at Lindy AI

Week #06
This week we updated our infrastructure and SDK and worked on the E2B docs.
Infrastructure
Worked on the custom playgrounds and CLI for managing the AI playgrounds
Updates in SDK
Improved speed of starting playgrounds in the Python SDK
Allowed users to set timeouts when using playgrounds in JS SDK to limit the maximum time playground methods can run
Added logging to the JS SDK
Documentation
Worked on improving user experience in the documentation, so users can quickly try E2B SDK right from their browser

Cloud playgrounds for AI copilots
This week we launched AI Playgrounds, supporting Python and JS/TS.
It is a sandboxed cloud environment where an AI agent or copilot can freely run code, use a filesystem, use a headless browser, and more.
Try the AI playgrounds here: https://e2b.dev/docs.
Every playground has its own URL, which allows your agent for example to start a web app. AI playgrounds are especially useful for coding copilots and agents. They can easily run linters, formatters, or debug code and feed all this information back to LLM to make the next iteration better.
Quality of life improvements
An API key is now required for our SDK (get your API key here)
Added timeouts to asynchronous methods in our SDK
Improved Python SDK debug logging
Improved internal overview of the usage of our infrastructure
Added periodic end to end test of our infra via calling SDKs
