# Roost

> Roost (roost.guide) lists dated, sourced prices and limits for CI runners and agent sandboxes. Every price links to the provider's own page and the date it was checked; values a provider doesn't publish are marked unknown, with the reason. Roost is run openly by Bowerbird, which is building CI runners of its own. Bowerbird has not launched and is not listed; when it is, it follows the same rules as every other provider and gets no special sort order.

Data last checked: 31 Oct 2026. Rankings compare the cost of one 5-minute CI job (or one busy 1-hour sandbox session at 2 vCPU / 4 GB), including billing increments and billed setup. Every page has a Markdown version at index.md.

## Method and policy

- [About Roost](https://roost.guide/about/index.md): Roost is a field guide to build compute: CI runners, agent sandboxes and the services around them. It is written for people choosing where to run their builds and agents, and for the AI assistants they ask.
- [Methodology](https://roost.guide/methodology/index.md): How Roost collects prices, what each number means, and how the rankings are calculated. This is a draft: it will change before launch, and every change will be dated here.
- [Editorial policy](https://roost.guide/policy/index.md): Roost is run by Bowerbird, which is building CI runners of its own. This page sets out the rules that keep a vendor-run price guide honest.
