# Preloop

6 Hacker News commenters recommended Preloop and 1 criticized it, November 2025 to November 2026. It was recommended in 4 of 13 months.

**Verdict:** Open-source control plane that sits between AI agents and the tools they touch, and runs GitHub Actions locally in microvms. Critics note it is still beta.

## Why people recommend it

- Runs unmodified GitHub Actions locally (4 comments): "a way to run your unmodified Github Actions locally or self-hosted in isolated cross-platform microvms" ([source](https://news.ycombinator.com/item?id=49234674)) "Preloop uses the exact same protocol the official runner does and runs each job in microvms." ([source](https://news.ycombinator.com/item?id=49236730)) "It could be used for faster local dev loops and porting GHA to other servers." ([source](https://news.ycombinator.com/item?id=49235789))
- Follows official runner protocol closely (4 comments): "our (almost) drop-in rust equivalent which is a 10x smaller binary and has far lower idle rss" ([source](https://news.ycombinator.com/item?id=49242551)) "Preloop uses the exact same protocol the official runner does and runs each job in microvms." ([source](https://news.ycombinator.com/item?id=49236730)) "we follow the official runner protocol 100% so we should hopefully have more workflow-compat" ([source](https://news.ycombinator.com/item?id=49335263))
- Pauses and governs agent workflows (2 comments): "We handle the state management of pausing that headless workflow so you don't have to build custom polling logic into every bot." ([source](https://news.ycombinator.com/item?id=46693583)) "It grew into the thing I now use every day: a control plane that sits between my agents and everything they touch" ([source](https://news.ycombinator.com/item?id=49083042))

## What people warn about

- Still beta, not production ready (1 comments): "It's still beta, so I certainly wouldnt use it in prod just yet" ([source](https://news.ycombinator.com/item?id=50154854))
- Website hard to read (1 comments): "I appreciate how cool the website looks but its not very readable friendly" ([source](https://news.ycombinator.com/item?id=49242228))
