Profile

Hey HN,I've been building Aether, a background agent that takes production errors from Sentry and attempts to turn them into verified pull requests.When a new error hits your Sentry project:1. Sentry webhook fires with the stack trace, breadcrumbs, and context 2. Aether spins up an isolated Fly.io VM and clones the repo at the relevant commit 3. Agent analyzes the stack trace, reproduces the issue, proposes a fix 4. Starts the dev server, re-runs tests, and can verify the running app with Playwright (headless Chromium is pre-installed in every VM) 5. A review pass evaluates the diff before a PR is opened 6. Pushes to a feature branch and opens a GitHub PR, but only if verification succeeds 7

The company sits in the show hn launch segment, where it competes on its core product or service.

Its current recorded stage is Show HN launch.
