Launches
Introducing E2B Secrets
E2B Secrets keeps credentials outside the sandbox and injects them into the HTTPS request headers you configure, so agents can call external services safely.
Introducing E2B Embed
E2B Embed packages the runtime and dashboard for one machine. Ship it with your product and run sandboxes inside your customer's environment.
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.

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.
