Find the bug.
Fix the cause.
Prove the result.

HashMo Proof is our local-first Smart Debugger and Verification Studio in development. It aims to help developers and authorized AI agents reproduce failures, examine evidence, propose focused repairs, and independently retest whether changes actually work.

What we're building

From a bug report to a result you can inspect.

Proof is designed to work alongside the tools developers already use—not replace their judgment.

01 / REPRODUCE

Observe the failure

Run an approved test scenario, capture browser or parser diagnostics, and preserve what happened.

02 / INVESTIGATE

Explore likely causes

Use source locations and competing hypotheses to guide investigation. A plausible explanation is not proof.

03 / RETEST

Verify the actual behavior

Compare the observed result with independent postconditions and supporting evidence—not just a success banner.

Development transparency

What works today—and what doesn't.

Implemented in controlled development tests

  • Real Chrome/Playwright save and reload tests on local fixtures.
  • Independent persisted-state checks with PASS, FAIL, and INCONCLUSIVE results.
  • Read-only JavaScript syntax diagnostics and controlled runtime source-location reports.
  • Versioned test cases, local journals, evidence receipts, and SHA-256 integrity checks.
  • Local read-only MCP status tools and experimental, time-limited local project consent.

Still in development—not yet available

  • General-purpose debugging of customer repositories and applications.
  • Autonomous patching or proven root-cause identification.
  • Authenticated remote AI clients via the shared HashMo MCP Gateway.
  • Production desktop UI, installer, signing, and commercial licensing integration.
  • Customer-ready sandbox isolation and security certification.

Our passing tests validate specific controlled behaviors. They do not mean Proof is ready for customer installation or that every bug can be diagnosed.

Who we're building for

Builders who need confidence, not just another green checkmark.

Independent developers

Reproduce a defect without losing the context of what failed, when, and where.

AI-assisted teams

Help authorized agents propose investigations while preserving human-owned permissions.

Small software studios

Keep meaningful acceptance evidence as products evolve and regressions appear.
