Launches
E2B sandboxes are now available through Stripe Projects
AI agents can now provision and authenticate E2B sandboxes directly through Stripe Projects.
E2B is now supported in the OpenAI Agents SDK
Building long-horizon agents just got easier.
Docker & E2B partner to introduce MCP support in E2B Sandbox
E2B partners with Docker to bring native MCP support to every sandbox — 200+ tools from the official Docker MCP Catalog, available to agents out of the box.
Introducing Build System 2.0
A faster and simpler way to create custom sandboxes in E2B
Weekly updates
Sep
- Public Project IDs & Embed OpenTelemetry ExportThis week improves projects and self-hosting with public project IDs in the dashboard and API, one E2B Console for every region, a dashboard-wide support dialog, and OpenTelemetry export for E2B Embed.
- V2 Sandbox Endpoints & CLI Sandbox ForkThis week adds v2 sandbox create and connect endpoints in the SDKs and a CLI command to fork sandboxes.
- E2B Embed & Automatic 429 RetriesThis week adds E2B Embed, automatic SDK retries, and an OpenAI Agents API guide with public examples.
- Workspaces & Cursor IntegrationWorkspaces are rolling out in the console, and new templates connect Cursor Self-Hosted Machines to E2B. This week also adds HTTPS backend ports, higher Python SDK concurrency, and new integration guides.
Aug
- Wildcard Transform Rules & Server-Side API Key ValidationThis week improves sandbox networking and authentication with wildcard domains in transform rules, server-side API key validation, and readable proxy errors for browser requests.
- Bring Your Own Proxy & Sandbox List FiltersThis week routes sandbox egress through your own SOCKS5 proxy, adds sorting and filters to sandbox listing, and ships snapshot management commands in the CLI.
- Workload Identity in the SDKs & Faster Python HTTPThis week ships sandbox workload identity in both SDKs, moves the Python SDK onto a Rust HTTP stack, and returns detailed sandbox placement failure reasons.
- Self-Hosted Proxy Retirement & Template Cert RepairThis week retires the deprecated reverse-proxy service on self-hosted clusters, repairs SSL trust stores baked into templates, and unblocks Python SDK installs alongside newer wcmatch.
- Access Tokens Disabled & Multi-Distro TemplatesAccess tokens are now disabled; authenticate the CLI with E2B_API_KEY instead. This week also improves templates and terminal workflows with Fedora, Alpine, Arch, and NixOS base images, CLI session flags, and cross-runtime detection of web platform objects.
Jul
- Projects Rename, Symlink Support & Python SDK TransportThis week improves the CLI and SDKs with the team-to-project rename, symlink listing in filesystem calls, and a rebuilt Python transport layer.
- Sandbox Forking & Snapshot Name FiltersThis week improves sandbox provisioning and snapshot workflows with in-place sandbox forking, name-based snapshot lookup, and Docker-compatible template file copying.
- Storage, sandbox reliability, and template build fixes
