Changelog

Build of docker image for a new template is now done on user's local machine instead of E2B's cloud. Here's how this new approach improves the DX:

• Allows referencing private docker images
• Manages build cache
• Higher iteration speed
• Prevents uploading node_modules or venv by accident
• Option to use a 3rd party service like GitHub Actions to build the sandbox template.

To build a new template users have to upgrade their CLI to the newest version:

npm install -g @e2b/cli@latest

• Bug fix: Remove extra whitespace when logging to Docker on Windows
• Bug fix: Make sandbox kill command work with the long form of sandbox ID
• Bug fix: Fix clock drift on startup

• Infra: Remove a template alias when sandbox template is deleted
• Infra: Deny access to Consul by default
• Infra: Don't cleanup nomad logs on restart
• CLI: Improve cross platform compatibility of e2b template build command

Product roadmap

See the public roadmap with planned features here.

Fixed bugs and improvements

• Fix enforcing the limit of concurrent sandboxes per team

Product roadmap

We released a public roadmap on GitHub to share features and bugs that we are working on. If there is anything you would like to see us add, please open an issue on our GitHub.

Multiple consul and nomad servers

We added an option to manage multiple Consul and Nomad servers simultaneously.

Other fixed bugs and improvements

• Export all errors and exceptions
• Raise proper exception on process.wait timeout
• Add temporary limit for concurrent new sandbox requests
• Make client startup script rerunnable

This week we were working on a new CodeInterpreter API. It's still in its experimental phase, but we love to hear your feedback. We added support for multiple Nomad and Consul servers.

Other fixed bugs and improvements

• Change auth buttons to links
• Update CLI commands in the guide to reflect the latest CLI version
• Standardize text format and grammar across CLI commands, args, and options
• Add email authentication

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

Other fixed bugs and improvements

• Fix upload path for FC versions
• Add command for killing sandboxes in our experimental SDK
• Release CLI v0.3
• Document process for customizing sandbox compute
• Fix type issue in Python 3.8

Getting started with sandboxes

If you want to try the sandboxes, start here and let us know at hello@e2b.dev if you need any support.

We enabled billing on E2B. Read more here about what we charge for and how to monitor your usage. We added the Your Usage page to our Docs to monitor your spending.

Fixed bugs and improvements

• Go context used for tracing is not closed properly
• Change max length based on the team tier

You can now connect your storage buckets to the sandbox. Connecting your cloud buckets is useful for filesystem persistence or giving the sandbox access to your data. This is achieved via the FUSE protocol which is supported by all popular cloud buckets: Amazon S3, Google Cloud Storage, and Cloudfare R2.

Get started here.

Fixed bugs and improvements

• Add FUSE to docs
• reconnect() now accepts API key
• Enable billing for users
• Experimental stateless SDK
• Fix incorrectly deleting template files when deleting templates
• Add API endpoint for instantly killing sandboxes
• Fix the issue preventing using any Debian images because of incorrectly called bash

This week a contributor Keegan McCallum from our community built an example of a code interpreter with AutoGen and E2B sandboxes used for the LLM code execution.

Fixed issues:

• ValidationError for SubscriptionArgs handler

Merged PRs:

• Fix broken provisioning for some Debian versions

Merged PRs:

• List running sandboxes

Fixed issues:

• JS SDK - Reject promises the correct way
• Python SDK Websocket reconnect sometimes takes unnecessarily long
• Unable to create custom templates with Dockerfiles containing more than ~4.3GB of local data
• Kill WebSocket and refresh threads automatically after close or program exit
• Using sandbox.download_file on an empty file throws error
