Fix production bugs in seconds, not deploys.

Your users report bugs in-page. AI drafts a scoped, constrained fix. Your team previews and approves it — and it's live for every visitor over WebSocket, cryptographically signed, while a real pull request opens with the permanent fix. When the PR merges, the patch retires itself.

46 minutes

How long a one-line fix can take to clear a typical CI/CD pipeline¹ — Sarcio delivers an approved fix in seconds.

< 1 hour

DORA's bar for elite failed-deployment recovery; low performers take up to a week². Sarcio is the fast path to restore.

$2M / hour

Median cost of a high-impact production outage³. Every minute a known bug stays live is money.

How it works

From "it's broken" to "it's fixed" — one governed pipeline.

No war room, no emergency deploy, no SSH. One flow takes a bug from in-page report to a live, signed, reversible fix — with the permanent source fix already in flight.

1

Report in-page

Anyone — a QA engineer, a client, a support agent — flags the bug where it happens. Console, network, and screenshot context attach automatically.

2

AI drafts a scoped fix

Triage plus a minimal, constrained patch with a computed (never AI-asserted) risk tier and a hard expiry. The AI drafts; it never ships.

3

Preview in isolation

See the fix applied for you alone before anyone else does. The broken behavior keeps failing for everyone until you say otherwise.

4

Approve — twice, if risky

A human signs off on every patch. Elevated-risk changes require two distinct approvers before anything is signed.

5

Live in seconds

The signed patch pushes to every visitor over WebSocket — no reload, no redeploy. Retire it any time with one click.

6

The PR opens itself

A pull request with the permanent source fix opens on GitHub, GitLab, or Bitbucket. When it merges, the patch auto-retires.

No patch debt

Every patch is a bridge to a merged pull request.

The classic objection to hotfixing is drift: quick fixes that outlive everyone's memory. Sarcio is designed so a patch cannot silently outlive its fix.

Right now

A temporary, signed, time-boxed patch

  • Live for every visitor seconds after approval
  • Hard TTL with client-side expiry rollback
  • One-click retire reverts the site live
  • Expiry reminders before anything lapses
Already in flight

The permanent fix, as a real PR

  • Opened automatically on your forge with the source fix
  • Merge it — the patch retires itself
  • PR closed or stalled? The patch is flagged as orphaned
  • Jira ticket filed and transitioned as the fix lands
Three patch kinds

One signed pipeline, covering your whole stack.

DOM

Visual & markup bugs

Constrained DOM operations — never arbitrary JavaScript — applied by a ~6KB widget in the browser. Perfect for the hidden required field, the broken banner, the unclickable button.
Server

API & backend bugs

Declarative request/response rules — default a field, set a header, skip a validation, reshape a response, gate a route — enforced by a self-hosted sidecar behind Node, PHP, Java, or WordPress. Fail-closed by design.
Module

Real logic bugs

Replacement code for exactly the modules a source fix touches, hot-swapped in place with component state preserved — in the browser, in web workers, and across Node clusters with a canary rollout.
Works with your stack

Frontend to backend, four languages deep.

One protocol, one signing scheme, verified identically everywhere — so an approved fix lands on every tier of your stack at once. See all integrations →

Who it's for

Built for the teams who own the worst day.

Agencies

A client's site breaks after a plugin update. The report widget replaces the panicked phone call, the WordPress plugin covers both tiers in one install, and the fix retires itself when the real one ships — no snowflake sites.

E-commerce

A checkout bug during a code freeze is measurable lost revenue. Constrained, reversible, audited ops are a freeze-safe break-glass path — with the paper trail your change board wants.

Platform & SRE

Your deploys are safe but slow, and MTTR is your KPI. Patch the symptom in seconds, canary it on real traffic in Node clusters, and let the permanent fix ride the pipeline at its own pace.

Small product teams

No dedicated SRE — the person fixing prod is also building the roadmap. Reports arrive with full context instead of vague screenshots, and the AI drafts the diff you were going to write anyway.
Security

More controlled than a panic deploy.

Patching production is only scary when it's ungoverned. Sarcio is the governed version — built to hand to your security reviewer. Read the full security model →

Ed25519-signed manifests — verified in the client against your workspace's own key before anything applies

Constrained operations — hard deny-rules enforced server-side; never arbitrary code

Two-approver gate — for elevated-risk patches, with preview-before-live for every change

Self-hosted server tier — outbound-only sidecar, no inbound credentials, fail-closed

Append-only audit log — every sign-in, approval, rotation, and retirement — exportable as CSV/JSON

RBAC, mandatory 2FA, OAuth sign-in — plus scoped API tokens over a default-deny surface

Per-tenant keys — envelope-encrypted at rest — a leaked credential is scoped to one workspace

Builds in your own CI — your source never has to transit Sarcio’s infrastructure

FAQ

The questions your reviewers will ask.

Sarcio is a governed break-glass path, not a cowboy console. Patches are constrained operations — never arbitrary code — validated server-side, previewed in isolation, approved by a human (two approvers for risky changes), signed, time-boxed with a hard expiry, reversible in one click, and recorded on an append-only audit log.

Every patch is verified in the client against your workspace's own Ed25519 signing key before anything is applied. Even a fully compromised delivery channel cannot push an unsigned payload to your users. The server tier verifies in a sidecar you host yourself, with outbound-only connections, and fails closed.

Every patch ships with the pull request that makes it permanent. When the PR merges, the patch retires automatically. Patches carry hard expiries with reminder emails, live patches sit on one dashboard, and a patch whose PR was closed or stalled is flagged as orphaned — a patch cannot silently outlive its fix.

The AI only drafts. A human previews every patch in isolation and approves it before it goes live, and risky changes require two distinct approvers. DOM and server patches are constrained operations validated server-side — the AI cannot emit arbitrary code into them. Module patches are built from your repository and reviewed like any code change.

Sarcio is built for review: per-tenant signing keys, role-based access control, mandatory two-factor authentication, OAuth sign-in, envelope encryption at rest, scoped API tokens, an exportable append-only audit trail, Jira change tickets, and module builds that can run in your own CI so your source never transits Sarcio’s infrastructure.

The browser widget is a small self-contained script of roughly 6KB gzipped that loads asynchronously and never blocks rendering. Heavier capture features like screenshots are lazy-loaded only when a report is actually filed.

The next production bug doesn't need a deploy.

Create a workspace, drop the widget on a site, and take your first report to a live, signed fix — with the permanent PR already open.
