Evaluate every code change against production reality.

Proofline probes the systems your application depends on, then verifies that the permissions, infrastructure, configuration, and deployment paths required by the change exist in each environment.

Your reviewers get a defensible decision before merge. You get fewer late-night deployment failures.

The diff looked right. The deployment would still fail.

A product PR introduced an AgentCore runtime and a new secret. The application code passed review. Staging still lacked the permission AgentCore needed to read that secret, so the service would fail at boot. Proofline found the missing grant before merge.

Catch deployment blockers earlier

Find missing permissions, broken release paths, configuration conflicts, and unmet infrastructure requirements while the change is still easy to fix.

Standardize the go/no-go decision

Apply one production-readiness policy across repositories and teams without turning the platform group into a manual approval queue.

Give every decision an audit trail

Preserve what was checked, which policy applied, the evidence used, and why the change was ready or blocked.

See the production requirement that blocks the merge.

Review the affected environments, inspect the evidence behind each check, and give the team a precise path to ready.

Give every team the production judgment your best engineers make.

Proofline turns hard-won infrastructure knowledge into a repeatable review standard, without adding another manual approval queue.

MERGE WITH CONFIDENCE

Proofline verified each requirement in the environments this change will reach.

FIX BEFORE MERGE

Your team sees the production gap, the affected environment, and the evidence needed to fix it.

REVIEW THE UNKNOWN

Proofline flags missing evidence for a human decision instead of guessing that the change is safe.

From pull request to evidence-backed decision.

Proofline gives reviewers the production context they need without sending them across CI, IaC, cloud consoles, and runbooks.

  1. 1

    Understand the change

    Identify the production guarantees that the change depends on.

  2. 2

    Check your systems of record

    Verify those requirements across CI/CD, infrastructure, identity, configuration, and runtime sources.

  3. 3

    Apply your readiness policy

    Use organization-level controls to decide what must pass, what blocks, and what needs review.

  4. 4

    Return a decision

    Put Ready, Blocked, or Needs evidence—plus the complete record—back into the pull request.

Production policy that scales beyond tribal knowledge.

Proofline discovers production requirements from repositories, infrastructure, runbooks, and past incidents. Platform teams review the knowledge once, then apply it across services and environments.

Engineering velocityBrings decision evidence into the pull requestShorter high-risk reviews
Change governanceRecords the policy, evidence, and decisionConsistent, inspectable approvals
One shared standard

Platform teams set organization policy centrally. Service owners keep their delivery workflow, and every team sees the same clear decision where they already review code.

Evidence from the systems that determine what reaches production.

Proofline brings deployment evidence together across source control, CI/CD, infrastructure as code, cloud identity, Kubernetes, configuration, and observability—then ties every finding to the exact change and environment under review.

Evidence from every system it depends on

Proofline follows the change into source control, delivery workflows, infrastructure, identity, configuration, and runtime evidence. Each observation keeps its source and freshness.

Start with the deployment checks that cost you the most.

Connect the systems your teams already use. Proofline discovers candidate requirements from code, infrastructure, runbooks, and incidents, then runs in observe mode before you enforce a policy.

Questions before a demo

What is Proofline?

Proofline is a deployment assurance platform. It verifies that a proposed change meets the permissions, configuration, workflow, infrastructure, and policy requirements needed to reach production safely.

Does it replace code review or CI?

No. Code review evaluates the implementation, and CI tests the build. Proofline verifies the production assumptions those tools do not establish on their own.

Can teams override a decision?

Your organization defines which checks block, which require review, and who may approve an exception. Every exception is explicit and retained with its reason and evidence.

Does Proofline change production?

No. Proofline uses read-only connections to evaluate evidence. It does not modify source code, infrastructure, configuration, or runtime systems.

How do we roll it out?

Start with a small set of high-cost deployment checks in observe mode. Compare the results with current review practices, then expand coverage and enforcement by service, team, or risk tier.

See Proofline evaluate a real production change.

We’ll trace the infrastructure assumptions behind one pull request and show the evidence your reviewers need before merge.

Bring a past incident. We can replay the change that caused it and show where Proofline would have raised the blocker.
