Open Agents is an open-source reference app for building and running background coding agents on Vercel. It includes the web UI, the agent runtime, sandbox orchestration, and the GitHub integration needed to go from prompt to code changes without keeping your laptop involved.

Smarter communication for growing businesses.

From @rauchg :

Today we're open sourcing http://open-agents.dev, a reference platform for cloud coding agents. You've heard that companies like Stripe (Minions), Ramp (Inspect), Spotify (Honk), Block (Goose), and others are building their own "AI software factories". Why?
On a technical level, off-the-shelf coding agents don't perform well with huge monorepos, don't have your institutional knowledge, integrations, and custom workflows.
On a business level, the moat of software companies will shift from 'the code they wrote', to the 'means of production' of that code. The alpha is in your factory.
Open Agents deploys to our agentic infrastructure: Fluid for running the agent's brain, Workflow for its long-running durability, Sandbox for secure code execution, AI Gateway for multi-model tokens.
(Because of our focus on Open SDKs and runtimes, this codebase is a gem even if you're not hosting on Vercel.)
TL;DR: if you're building an internal or user-facing agentic coding platform, deploy this:

If you assume prompt injection is inevitable, what’s the practical security posture you recommend for a production deployment (secrets handling, network egress, tool permissions, approval gates), and which parts do you expect teams to customize first?

love this

going from prompt to actual code changes without staying in the loop is where things get interesting

nice to see this as an open reference as well

how are you handling sandbox isolation for different tasks?
