Streaming Uploads & Idempotent Sandbox Creation This week adds streaming file uploads and idempotency keys for sandbox creation. Paginated template list in the CLI The e2b template list command now pages through templates, showing 1,000 by default, with --limit to change it. With -f json , it still returns every template by default.
E2B sandboxes now support DNS server allowlists, streaming input for commands, and retry hints for sandbox creation errors.
Pause Mode Reporting, SDK Runtime Requirements & Project Deletion This week improves sandboxes, the SDKs, and the dashboard with pause mode reporting, new minimum Node.js and Python versions, and project deletion.
Filesystem-Only Snapshots & Lifecycle Pause Modes This week improves snapshots and lifecycle events with filesystem-only snapshots, pause and resume modes, and clearer errors for stopped sandboxes. Filesystem-only snapshots Snapshots, pauses, and auto-pause now accept a mode option .
Broader SDK Retries, HTTP/1.1 Option & Dashboard Hold Banners This week improves SDK reliability and the dashboard with 502 and 503 retries, an HTTP/1.1 option, Docker-style ignore patterns, and hold banners.
Public Project IDs & Embed OpenTelemetry Export This 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 Fork This week adds v2 sandbox create and connect endpoints in the SDKs and a CLI command to fork sandboxes. V2 sandbox create and connect endpoints Sandbox.create and Sandbox.connect now call POST /v2/sandboxes and POST /v2/sandboxes/{id}/connect , and the SDKs stop presetting timeout , allow_internet_access , count ...
E2B Embed & Automatic 429 Retries This week adds E2B Embed, automatic SDK retries, and an OpenAI Agents API guide with public examples. E2B Embed for self-hosted deployments Run E2B on your infrastructure with Docker Compose, Terraform, or Kubernetes deployments and pinned service images.
Workspaces & Cursor Integration Workspaces 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. Workspaces are rolling out Workspaces bring your projects and access management into one place in the E2B Console.
Wildcard Transform Rules & Server-Side API Key Validation This 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 Filters This 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 HTTP This 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 Repair This 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 Templates Access tokens are now disabled, so 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.
Sandbox Forking & Snapshot Name Filters This week improves sandbox provisioning and snapshot workflows with in-place sandbox forking, name-based snapshot lookup, and Docker-compatible template file copying. Sandbox forking You can now fork a running sandbox to spin up one or more clones from its exact in-memory state.
Projects Rename, Symlink Support & Python SDK Transport This week improves the CLI and SDKs with the team-to-project rename, symlink listing in filesystem calls, and a rebuilt Python transport layer.
Self-hosted deployments backed by AWS S3 can now upload template layers with the same compressed transfer path already used for other providers, cutting bandwidth on large template builds. ( #3232 )
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 .
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 .
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.
E2B Artifacts Add support for Gemini Pro 1.5 002, Gemini Flash 002, and Mistral Small models Infrastructure Add proper sandbox duration limit to the API Core & Code Interpreter SDK Fix RPC issue causing Server disconnected without sending a response
