Mistle – Open-source infrastructure for running sandboxed coding agents

About

Hi HN, I'm Jonathan. My co-founder, Thomas, and I started building Mistle in Feb.We saw larger tech companies like Ramp (Inspect) and Stripe (Minions) build this internally and thought an open source version should exist.We made a few very intentional decisions when working on this:1. Credentials are kept out of the sandbox. Authorized access goes through a proxy, so agents do not directly receive credentials.2. The harness is not our problem. We're not going to tackle things like memory, self-learning.3. No magic. Configurations are explicit. You can bring your own keys for models, sandboxes, and other providers. You can write your own instructions and agent.Mistle can be run locally with a single command: https://github.com/mistlehq/mistle#run-mistle-locallyQuestions, feedback and ideas are welcome!
