Now in beta

Your CI failed. We fixed it.

Autonomous agents that fix broken builds and open PRs — while you sleep.

How it works

From failure to fix in minutes, not hours.

01

Signal arrives

CI fails, Sentry fires, or you trigger via API

02

Agents spin up

Specialized agents coordinate in an isolated VM with your repo and secrets

03

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.

Code generation
  • Generates a diff
  • Hopes it compiles
  • You test it manually
  • Finds out it's broken when CI runs
Code execution
  • 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.

VM
RepoSecretsMulti-Agent Swarm
PR

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.
