Tools give data, not answers
Sentry, logs, and metrics hand you ten thousand signals. Turning them into a root cause is still manual, slow, and on you.
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.

Debugging is detective work
You jump between traces, logs, and code, trying to reproduce an incident, usually mid-task and sometimes mid-sleep.

@you, can you take a look?
It always lands at 2am
A Slack ping or a pager alert drags you out of focus, and the clock starts the moment you open the laptop.
Trace user's action
Find the code path
Reason about the root cause
Try to reproduce it
Draft a fix
…and again, next incident
The same 80%, every incident
Gather evidence, find the code path, reason about the cause, draft a fix. The same loop, every time. It should be automated.
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.

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.
Be first to let Phagon take the 2am page.
