Open-source IDE powered by AI agents that do the work for you

Example of AI agent building Stripe checkout. Left - technical specification written by human. Right - steps that the AI agent took and tools that it used to build the server route required by the specification.

e2b or etob (english2bits) is a new kind of development environment powered by AI. The main idea is that developers have access to AI agents that can use tools. The developer writes a short documentation or a technical spec in plain English and then lets the AI agent do the actual work. The AI agents have access to tools like writing to a file, running code, running commands, installing dependencies, deploying, etc. Agents operate in a secure sandboxed cloud environment that's powered by Firecracker. This way, you for example describe what a server route should do and the agent codes it for you. Like this example of an AI agent coding Stripe customer checkout based on a technical spec.

e2b currently supports building only REST servers in Node.js. Specifically using the Express framework. We'll support more languages and frameworks with time. The goal for e2b is to eventually be able to handle any use-case.

🚀 Get started

We're working on the cloud-hosted version. In the meantime, the fastest way try out e2b is to run it locally via Docker.

You will need:

OpenAI API key (support for more and custom models coming soon)
Docker
Node.js 16+
Free ports 3000 (Next.js app), 54321 (Supabase API Gateway), 54322 (Supabase Database)

The first start of the Dockerized app is slower because it downloads and builds all the necessary containers. On a 2CPU 4GB RAM machine it takes cca. 6 minutes and doesn't require any interaction. The subsequent starts are way faster.

1. Add env var

Create .env file by copying the .env.example

cp .env.example .env

and fill in the following variable:

OPENAI_API_KEY - your OpenAI key

2. Start the app

npm start

Then open the page on http://localhost:3000.

npm run start starts local Supabase in the background - to stop it you have to run npm run stop.

If you want to run the project without using containers use the steps here. This is useful if you want to leverage hot reloading and develop the project.

Features

🛠 Bring your own X

While e2b will offer the "batteries-included" solution, our goal is to let users:

BYOM - Bring Your Own Model
BYOP - Bring Your Own Prompt
BYOT - Bring Your Own Tools

We think the AI-powered IDE for the future should be open-sourced and allow anybody to bring their models, customize the prompts, and develop custom tools for the agents. But we also plan to offer a cloud version with some features behind subscription though.

🤖 Supported models

GPT-4
GPT-3.5
More coming soon.

📆 Roadmap

Make sure people can run e2b locally without issues and the DX is smooth.
Add support for more models.
- Let users request new models. Laterm create a system that will let users use any model.
Improve model's understanding of the context based on the instructions
Support for more tools
Improve the dashboard UI
Let users edit prompt
Let users customize tools and build custom workflows for the agent
Release cloud version

💻 Development

For developing with hot reloading and contributing to the project you may want to run the app locally without Docker Compose (npm run start command). Here are the steps for how to do it.

You will need:

OpenAI API key (support for more and custom models coming soon)
Docker
Node.js 16+
Python 3.10+
Poetry 1.3.2+
Free ports 3000, 49155, 49160, 54321, 54322

1. Install dependencies

npm run install:all

2. Start local Supabase

npm run db:start

Local Supabase runs in the background - to stop it you have to run npm run db:stop.

3. Add env vars
