E2B

AI development is moving from experimentation to production. That shift demands infrastructure that’s secure, standardized, and fast. Docker is excited to partner with E2B, a platform for running AI-generated code in secure cloud sandboxes. Through this partnership, developers using E2B sandboxes can now access Docker's MCP Catalog - giving developers access to a library of trusted MCP tools like GitHub, Perplexity, Browserbase, and ElevenLabs. Teams can build AI agents that connect to real-world tools without compromising security. This is a huge step toward a secure foundation for the next generation of AI development.

Today, we're introducing the new Build System 2.0 for E2B. We've completely rebuilt how custom sandboxes are made from the ground up while being focused on 4 main goals: 1️⃣ Better DX 2️⃣ Agent-first experience 3️⃣ Speed 4️⃣ Painless Migration 💬 Get started in the comments section 1️⃣ Better DX Until now, creating a custom sandbox took a YAML config file, a Docker file, and running a terminal command. The DX was pain. Now, everything is just code. Want to build a custom sandbox with the premade Next.js app? That's about 7 lines of code. 2️⃣ Agent-first experience Because custom sandboxes are just code now, AI IDEs and agents like Cursor or Claude Code can parse, suggest, and generate them without any extra config. And it works extremely reliably. 3️⃣ Speed We moved the build step to our servers and the Build System 2.0 is now up to 14x faster. Making the feedback loop much friendlier. You should see pretty big improvements most of the times because our caching (that we can control thanks to moving to cloud) will kick in. 4️⃣ Painless Migration The new system is fully backwards compatible. On top of that, we added several migration paths for our users to make the migration as easy as possible. Update to the latest E2B CLI version and run `e2b template migrate` All this was built by our amazing engineers Jakub Dobry and Mish Ushakov. Together with feedback from our wonderful users which made all of this possible 🧡
