Your CI failed. We fixed it.
Autonomous agents that fix broken builds and open PRs — while you sleep.
No credit card required
How it works
From failure to fix in minutes, not hours.
Signal arrives
CI fails, Sentry fires, or you trigger via API
Agents spin up
Specialized agents coordinate in an isolated VM with your repo and secrets
PR opens
Fix verified, tests passing, ready for review
Other AI tools write code. Aether runs it.
The difference between code that looks right and code that works.
- Generates a diff
- Hopes it compiles
- You test it manually
- Finds out it's broken when CI runs
- Writes the code
- Installs dependencies, starts the dev server
- Gives you a live preview URL instantly
- Opens a browser and verifies it works
- Runs the test suite before opening the PR
Why Aether
Real infrastructure for autonomous bug fixing. Not another chatbot wrapper.
Proof, not promises
Agents run in real environments. They reproduce the bug, fix it, verify it works, and show you the evidence.
Instant preview URLs
Every port gets a live URL automatically. The agent starts your dev server and you can see it running — no deploy, no tunnel, no config.
20 issues, 20 agents
Parallelize your backlog. Monday morning triage becomes Monday morning PR review.
Plug into what you have
Sentry, GitHub Actions, Slack, cron. One webhook, it just runs.
Two ways to use Aether
Hands-off or hands-on. Same environment, same agent, your choice.
Autonomous Mode
Trigger via webhook, API, or cron
The agent works in the background — clones your repo, reproduces the issue, fixes it, runs tests, and opens a PR. You review when you're ready.
Interactive Mode
Describe what you want in chat or CLI
Watch the agent build in real-time. Intervene, redirect, or approve as it goes. Like pair programming with an agent that has a full dev environment.
Built for trust
Enterprise-grade security, from the ground up.
Firecracker microVMs boot in ~30 seconds, giving each agent complete isolation. Your secrets are encrypted at rest, decrypted only at boot, and wiped on shutdown.
Network egress is allowlisted to prevent exfiltration. Full isolation between agents means one compromised task can't affect another.
- Firecracker microVMs (~30s boot)
- Secrets encrypted at rest
- Allowlisted network egress
- Complete agent isolation
Use cases
Automate the work you shouldn't be doing manually.
PR goes red → agent fixes → CI goes green
No context switch. No debugging session. Just a PR ready for review.
