Professional review steps—free in your browser

Solve the expensive part: find the risk, fix the input, export the proof.

FastTool does not pretend to replace an entire enterprise platform. It makes one high-value review step usable without an account, keeps supported inputs local, and leaves exact artifacts another person can check.

Reviewed workflow01

Protect search traffic while moving a site, domain or URL structure.

Compare inventories, expose collisions and chains, then export deployment rules and rollback evidence.

Reviewed workflow02

Turn recurring DMARC report piles into the senders you need to investigate first.

Deduplicate bounded RFC 9990 reports, separate authentication evidence, and export a repeatable remediation packet.

Remove private screenshot pixels before a client or colleague can recover them.

Solid-fill selected zones, re-encode and re-decode the PNG, then export zone-level pixel proof.

Reviewed workflow04

Find hidden Excel links and risky formulas before sharing the workbook.

Inspect the OOXML package locally without executing macros; export a finding ledger and dependency map.

Publication boundary: this shelf is generated from the reviewed release allowlist. Exact current QA report hashes are published in the machine-readable quality manifest; tool inputs, results and exports remain ad-free.

Everyday tools with an honest output contract

Finish the file task first. Keep the proof if you need it.

Only reviewed, indexable workflows are discoverable here. Every card states the real output format and verification boundary before you choose a file.

Every available workflow

Choose by the result you need—not by a vague category.

Browse all eight reviewed public tools here. Direct-access betas remain outside homepage discovery until their full release gates pass.

Reviewed workflows

Quality-gated and discoverable

Reviewed workflow · WAV output Audio Cutter

Trim MP3, WAV, M4A or OGG locally; replay the result and export a verified PCM WAV with exact input/output hashes.

WAV + downloadable JSON/Markdown receipt Reviewed workflow Screenshot Redaction Proof Studio

Remove selected pixels permanently, re-decode the PNG and verify the exact exported zones before sharing.

Sanitized PNG + zone proof + receipt Reviewed workflow Receipt Verifier

Recompute a receipt core and supplied artifact hashes locally; distinguish intact, changed and incomplete evidence.

PASS / BLOCK / INDETERMINATE report

Choose the job, not a file converter

Five workflows built around decisions people are accountable for.

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.

Primary flagship · SEO operations

Move a website without losing the URLs that already earn traffic.

Compare old and new inventories, separate exact matches from uncertain candidates, expose chains, loops and collisions, then export deployment rules and a QA packet.

You leave withRedirect decisions, deploy files, risk table, QA checklist and hash-backed receipt.
Open Website Migration Compiler
Application security

Stop new scanner findings before a release.

Validate SARIF 2.1.0, match findings with stable fingerprints, apply an explicit risk budget and preserve suppressions as visible evidence.

You leave withRelease verdict, delta data, visual summary, annotations and receipt.
Open SARIF Release Gate
Email authentication

Turn a pile of DMARC reports into a sender triage plan.

Parse XML, XML.GZ and ZIP reports, detect overlapping windows and duplicates, group senders, and separate SPF/DKIM alignment evidence.

You leave withSender inventory, failure priorities, triage exports and stated limits.
Open DMARC Triage
Visual privacy

Redact a screenshot so the hidden pixels do not come back.

Apply irreversible solid fills, re-rasterize the image, decode the output again, and verify the selected regions before sharing.

You leave withSanitized PNG, region proof, before/after hashes and receipt.
Open Redaction Proof Studio
ML data quality

Catch train/evaluation leakage before it inflates your model result.

Compare CSV splits for exact and near overlap, shared groups, time travel, target proxies and distribution drift with row-level evidence.

You leave withLeakage map, drift evidence, affected rows and release packet.
Open Leakage & Drift Lab

The output carries its own audit trail

A result is useful only when somebody else can check it.

FastTool evidence packets keep the analyzed bytes, method boundary, generated artifacts and receipt integrity connected. Missing evidence cannot quietly become PASS.

  1. 1
    Hash the exact input. A later file cannot be mistaken for the one that produced the decision.
  2. 2
    Export the working artifacts. CSV, JSON, Markdown, SVG or tool-specific files remain usable outside FastTool.
  3. 3
    Verify on another device. Receipt Verifier recomputes the receipt core and supplied artifact hashes locally.

Designed to earn trust, not borrow it

Free does not mean vague, disposable or unaccountable.

Each public workflow exposes what it accepts, what it produces, what sources shaped the method, and what the result cannot prove.

Real state

No fake result on first load

A result appears only after the user runs a fixture or provides an accepted input. Editorial examples remain visibly labeled.

Clear boundary

Privacy and limits stay attached

Local processing is claimed only where implemented. Files, names and raw user input are not placed into analytics events.

Reproducible

Benchmark, guide and correction path

Public fixtures show success and failure cases. Method notes, limitations, changelog and correction contact remain discoverable.

Browser + local CLI + vendored CI

Gate OpenAPI, SARIF and LLM changes in the repository—not after release.

FastTool Evidence v0.3.0 packages GitHub Actions privilege, OpenAPI, SARIF and LLM regression gates as a free local CLI and a self-contained CI Action archive you can vendor into your repository. Every run produces a reviewable packet with exact input hashes, artifact hashes and a verifier-compatible Receipt v1.

Node.js 20+ required. Exact release bytes are published directly by FastTool with a checksum manifest and Receipt v1. GitHub, npm and Marketplace publication are not claimed.
