Production bugs, fixed before they ruin your week.

Patcherly watches your live sites and apps, works out what broke, and writes the fix. You approve it, it applies on your own server, and one click undoes it.

How it works

Six stages you can watch. Every one reversible.

Every error walks the same path, and every step is visible in your dashboard: who approved it, when the connector ran, how it ended. New targets start in dry run, and you decide which paths can never be touched.

Help center → How rollback works →

Watch, without the log archaeology

Pair a target once and your errors land in one inbox. No tailing files over SSH, no pasting stack traces into chat. You set the scope, and nothing outside it is ever read.

Understand what actually broke

Each error is packaged with the trace, the surrounding code and the environment it happened in. Secrets are stripped on your server before any of it travels. You get a plain-language summary, not a cryptic log line.

Draft a fix for your code, not a generic one

The analysis runs on that context pack alone. We hold no standing access to your repo, your servers or your deploy keys, and the suggestion reads like something a colleague who knows your stack would write.

Show you the diff and a confidence score

Every proposal arrives with the exact change, a short explanation of why, and a confidence score. Anything under 90% needs a human, even with Auto Apply switched on. Nothing is patched blind.

Back up first, then verify live

The connector snapshots the affected files on your host before it writes anything. The moment the patch lands, a live check confirms your site still responds. If it does not, the snapshot goes straight back.

Leave a trail you can hand to a client

Who approved, what ran, how long it took, how it ended. All of it in your dashboard, exportable, and useful the next time someone asks what happened last Tuesday.

Letting software touch production code is a big ask.

We know. So we built Patcherly the awkward way round: your code stays put, your backups stay on your machine, and you keep the last word. Here is exactly what that means.

Your code never leaves your server

The connector lives on your infrastructure. We see a scrubbed error context and nothing else: not your repo, not your secrets, not your file tree. Backups stay with you, and your code never trains anyone’s model.

How the connector works →

Nothing applies until you say so

New targets start in dry run. Fixes queue up and wait. Auto Apply is opt-in on Pro, scoped to a single target, and revocable in one click. That switch belongs to you.

Dry run and approvals →

The undo button is on your side of the wire

Before a file changes, the connector snapshots it on your host with a sha256 manifest. We never copy that snapshot. Rollback runs from your machine, on your timing, automatic or manual.

Rollback guide →

Numbers that survive a finance review

Resolution rate, confidence, time to fix, hours saved. Live in your dashboard and exportable to CSV, XLSX or PDF, so it drops straight into a client report or a board deck.

Understanding metrics →

Security in depth, never a paid add-on

Authentication, data validation, code privacy, local snapshots, workspace isolation, encrypted transit, dashboard hardening, threat detection and prompt-injection defence. Active on every workspace from the first target, on every plan, including the free one.

Full security overview →

EU-hosted, GDPR-aligned

Your data runs and stays in the EU. The DPA is published and accepted at sign-up, subprocessors are listed in plain English, and deleting your account is one click in the dashboard.

Real fixes

From fatal to fixed, in under a minute.

Typos, missing null guards, wrong unpacking, unhandled async, the field an upstream API quietly stopped sending. Not glamorous, but they are what takes your site down and eats your evening.
These are the ones Patcherly is best at.

PHP · user_service.php

    $user = fetchUser($userId);

    // ✗ Fatal: missing null check
    return $user->getName();

✗ Fatal Error: Call to method on null
after.php
function getUserData($userId) {
    $user = fetchUser($userId);

    // Patcherly · Missing null-guard
    return $user ? $user->getName() : null;
}

Who it’s for

Three kinds of setup.
Same tool.

Developers and engineering teams

Get back the debugging hours nobody ever puts on a roadmap. Patcherly takes the repetitive triage so you can stay on the work you were hired for. Your PR flow and CI do not move an inch.

  • Dry run, path exclusions and approval rules per target
  • Time saved, resolution mix and exports in the dashboard

Agencies and small businesses

Look after more client sites without hiring. Fewer panicked calls, faster resolution, and a report you can send to a client without rewriting a thing.

  • Many sites and targets in one workspace
  • Per-error timelines and rollups for client reports

Solo builders and freelancers

Your app keeps working while you sleep, travel, or focus on the next release. Set and forget where you trust it, full manual approval where you do not. Your call, every time.

  • Free plan that stays free, no card on file
  • EU-hosted by default when clients ask about compliance
Numbers, not promises

What are production bugs actually costing you?

At roughly 90k visits a month, a typical team burns about €8,500 a year on manual debugging, and Patcherly cuts that by 57%. At 300k the saving is around €24,000 a year. At 3M, north of €250,000.

These figures assume you review and approve each fix yourself, so they include roughly 10 minutes of human approval per patch. With the Pro plan's Auto Apply feature on, a patch is applied and verified in under a minute.

The questions we get asked first.

Not answered here? Ask us directly, or dig into the help center.

Do I have to upload my repo or hand over SSH access?

No, and we would not want it. Patcherly runs through a connector you install on your own infrastructure. It sends us error context and writes patches locally. Nobody on our side logs into your servers, and your codebase never lands in our cloud.

Can it change production files without asking me?

Not unless you turn that on yourself. New targets start in dry run and every fix waits for your approval. Auto Apply is opt-in, available on Pro, scoped to one target at a time, and off again in one click.

What happens if a patch turns out to be wrong?

The connector takes a local snapshot before every apply. If the patch fails or the health check comes back unhappy, the original goes back immediately. Manual rollback is always one click away, for as long as the snapshot exists on your disk.

Is my code used to train AI models?

No. We use third-party AI for inference only, to draft a fix from a scrubbed error context. Nothing you send is used to train or fine-tune anyone’s foundation model. We do remember whether a fix worked, but only inside your own workspace, so future suggestions for your project get sharper over time.

How is this different from Copilot, Cursor or Sentry?

Those tools are excellent at their own jobs. Copilot and Cursor help you write code, Sentry and Datadog show you what broke. Neither closes the loop on the server. Patcherly picks it up from there: production signal, drafted fix, your approval, local apply, verification, rollback. Keep your IDE assistant exactly where it is.

Where does my data live, and is there a DPA?

The app, API and database are EU-hosted (Frankfurt) by default. The DPA is published at /legal/data-processing-agreement and accepted at sign-up, and every subprocessor is listed at /legal/subprocessors. You can delete your account yourself from the dashboard.

What does the free trial actually include?

The full Pro plan for 30 days: every feature unlocked, no credit card, no auto-charge when it ends. If you do nothing, your workspace simply moves to the free Personal plan and keeps running. Nothing is deleted.
