Now in early access

The immune system for your Software.

AI agents that continuously investigate live data, diagnose emerging issues, and generate preemptive fixes.

Debugging is fundamentally broken.

Modern apps break in production constantly, and the tools built to help stop at the data. The reasoning, the part that actually costs hours, is left to you.

@you, can you take a look?

Tools give data, not answers

Error monitors, logs, metrics, and analytics hand you ten thousand signals, but turning them into a root cause is still manual, slow, and entirely on you. Your team ends up chasing bugs instead of building, sometimes mid-task and sometimes mid-sleep.

3h 12m and counting…
Investigate the root cause
Find the code path
Reproduce the bug
Draft a fix
…and again, next incident

The same 80%, every incident

Investigate the root cause, trace the code path, work out how to reproduce it, draft a fix. The same loop, every incident, burning hours that were never the interesting part. It should be automated.

The Phagon dashboard: a triaged production error shown with its root-cause analysis, evidence, and a proposed pull-request fix.

From “bug reported” to “a fix I can approve.”

One agent runs the loop a human would. It investigates, analyses, and shows its work at every stage, so review becomes a confident approval instead of a re-investigation that eats your dev time.

Same incident. A completely different night.

What changes the moment one agent runs the loop a human would, and shows its work at every stage.

Without Phagon

  • A 2am page. You drop everything and start digging.
  • Ten thousand signals across logs and traces. None of them the answer.
  • Hours reproducing, tracing, and reading code.
  • Review means re-investigating the whole thing from scratch.
  • On-call dread that compounds with every release.

With Phagon

  • You wake to a triaged error and a fix already drafted.
  • The root cause, found and shown with its evidence.
  • Minutes reading a scoped pull request.
  • Review is a confident approval.
  • Trust that nothing breaks without an answer attached.

Plugs into the tools you already run.

Built to read from, listen to, and respond across the tools your team already lives in: the dev platforms, the chat, and the project boards where work actually happens.

  • Sentry
  • AWS CloudWatch
  • GitHub
  • GitLab
  • Slack
  • Notion

On the roadmap

  • Bugsnag Coming soon
  • Datadog Coming soon
  • Telegram Coming soon
  • Discord Coming soon
  • Jira Coming soon
  • Linear Coming soon
  • PagerDuty Coming soon
  • New Relic Coming soon

Autonomous where it's earned. In your control always.

You approve every fix

Phagon proposes; a human approves. Fixes land as pull requests you review from Slack or the dashboard, and nothing merges behind your back.

Policy you control

Per-project rules decide what's eligible for fast-track by confidence, files touched, lines changed, and risky-file checks. Tighten or loosen per environment.

The reasoning is legible

Every proposal carries its evidence: the trace, the matched code path, the severity reason, and the diff. You can see how it reached its conclusion instead of trusting a black box.
