Interactive matcher

Moderation Stack Matcher

Specify your content types, the harm classes you need to cover, your volume tier, latency budget, deployment constraints and budget sensitivity — and get a ranked shortlist of moderation tools and stacks, each with a harm-class coverage heatmap, a rough cost-per-million estimate, a false-positive note and a link to our hands-on review.

Hard constraints (modality, deployment, latency) filter the candidate set; remaining tools are ranked by a weighted harm-class coverage score against your budget. Everything runs in your browser and your spec is encoded in the URL. Coverage and cost figures are from our hands-on reviews (reviewed 2026-05).

What content types do you moderate?

A tool must cover every modality you check, or it is filtered out.

Which harm classes must you cover?

Weighted into the coverage score; tools with a hard zero on a required class are penalized heavily.

Volume tier (items per month)

Scales the cost estimate; very high volume favors cheap self-hosted options.

Thousands / mo Millions / mo Billions / mo

Latency budget

Sync inline moderation needs sub-300ms tools; async tolerates heavier models.

Synchronous — must block inline, < 300ms Asynchronous — review out of band is fine

Deployment constraint

A hard filter — air-gapped excludes every hosted API.

API is fine — calling a vendor service is acceptable Must self-host — no traffic to third parties Air-gapped — fully offline, no external dependencies

Budget sensitivity

Weights cost-per-million in the final ranking.

Cost-sensitive — minimize spend Balanced — cost matters but coverage wins Coverage-first — budget is not the constraint

All 12 tools & stacks we score

Coverage is graded per harm class: 2 = strong, 1 = partial, 0 = none. Cost-per-million is a rough order-of-magnitude estimate (USD), not a quote.
