Astro’s GitHub issue backlog is heading to zero for the first time in 5 years. Now Cloudflare is open-sourcing the tool that did it.

Astro, a JavaScript framework for building fast, content-heavy websites, has managed to reduce its GitHub issue backlog from over 200 to just around 20 issues in the past five years. The team behind Astro expects to reach a zero issue count within the next month. The key to this success lies in a tool called triagebot-action, which utilizes AI agents to automate the issue triage process.

Cloudflare, which acquired the Astro team in January, announced on Tuesday that it is open-sourcing triagebot-action for other maintainers to use. The tool uses a four-stage pipeline to handle issue triage, consisting of reproducing the bug in a sandbox, diagnosing the root cause, verifying it's a genuine bug, and attempting a fix.

The "fix" stage, however, is considered the most challenging, as it requires writing high-quality code that can be merged into the project. Astro's co-founder and now a senior engineering manager at Cloudflare, Fred Schott, explains that the triage aspect of the tool came first due to its reliability and the time-consuming nature of the task for maintainers.

Astro has maintained a full-time team of engineers and continues to operate independently, with a roadmap and release cadence. While the adoption of triagebot-action beyond Astro is still in its early stages, the underlying agent framework, called Flue, sits under the Astro organization and can run on any infrastructure without Cloudflare-specific tooling.
