Free evidence workflows for expensive mistakes
Analyze risky changes locally, export professional artifacts, and give reviewers exact hashes they can verify—without an account.
Useful tools are back
This is a deliberately small shelf: two media cutters verified on the live site and eight specialist tools with working samples, usable exports, visible limits and review evidence. Unfinished utilities are not promoted here.
Files stay in your browser for these cuts. Open a harmless sample first, check the result, then use your own media.
Open MP3, WAV, OGG or M4A locally, preview the selected range, export WAV and keep a copyable result receipt.
Local file · range preview · WAV download Live verified Video CutterTrim a short MP4, WebM or MOV in the browser, replay the selection and export a downloadable WebM with receipt.
Local file · selection preview · WebM exportInfer a conservative schema, review overrides and export migration-ready SQL plus SHA-256 evidence.
Data conversionXML → JSON Evidence StudioParse a safe XML subset, preserve repeated elements and namespaces, then export deterministic JSON proof.
Developer utilityRegex Explainer & Test MatrixExplain a pattern, run bounded test cases, inspect captures and export the exact test evidence.
Software securityDependency Exploit Priority RadarTurn dependency inventories into exposure-aware patch waves using visible OSV, KEV and EPSS evidence.
Audio productionDAW Missing Plugin RescueClassify missing-plugin notes and build a dependency map, recovery order and support packet.
Audio QAMix Recall Null-Test LabCompare two bounces for null depth, correlation, offset and drift; export a residual WAV and receipt.
Session recoveryPlugin Chain Recall DiffCompare an old chain with the current machine inventory and expose missing, format or version drift.
Official sourcesAudio Plugin Manual FinderResolve plugin names to official documentation, install paths, preset locations and support routes.
Choose the job, not a file converter
Each tool starts with a real input or an explicit sample, performs a narrow analysis, and exports reusable evidence. The result remains inspectable instead of disappearing behind a score.
Compare old and new inventories, separate exact matches from uncertain candidates, expose chains, loops and collisions, then export deployment rules and a QA packet.
Validate SARIF 2.1.0, match findings with stable fingerprints, apply an explicit risk budget and preserve suppressions as visible evidence.
Parse XML, XML.GZ and ZIP reports, detect overlapping windows and duplicates, group senders, and separate SPF/DKIM alignment evidence.
Apply irreversible solid fills, re-rasterize the image, decode the output again, and verify the selected regions before sharing.
Compare CSV splits for exact and near overlap, shared groups, time travel, target proxies and distribution drift with row-level evidence.
The output carries its own audit trail
FastTool evidence packets keep the analyzed bytes, method boundary, generated artifacts and receipt integrity connected. Missing evidence cannot quietly become PASS.
Designed to earn trust, not borrow it
Each public workflow exposes what it accepts, what it produces, what sources shaped the method, and what the result cannot prove.
A result appears only after the user runs a fixture or provides an accepted input. Editorial examples remain visibly labeled.
Local processing is claimed only where implemented. Files, names and raw user input are not placed into analytics events.
Public fixtures show success and failure cases. Method notes, limitations, changelog and correction contact remain discoverable.
Browser + local CLI + repository CI
The versioned FastTool Evidence v0.1.0 archive has published SHA-256 identities and includes the browser-parity SARIF engine, fixtures, tests and a verifier-compatible release receipt.
Node.js 20+ required. Direct download is the canonical v0.1.0 channel; npm, GitHub and Marketplace publication are not claimed.
