Pricing

Everything is FOSS: the code (MIT), the model weights (Apache-2.0 chain), and the database (nsfw.sqlite, weekly release). Paid plans fund operations — managed endpoints, freshness audits and support. Prices are placeholders; adjust in sys/config.php.

Free (OSS)

5,000 lookups/month

Domain lookups + DB download, rate-limited. Code and DB are free under MIT.

Indie

500,000 lookups/month

You host it yourself, MIT code, DB is free — this tier is running your copy.

Pro

$19/mo

5M lookups/month

Managed API endpoint, community support and the weekly refreshed health-audited download.

Data / Embedded

$99/mo

unmetered

Bulk export streams, WHOIS-verified freshness feed, hotline.

What is not for sale

The open DB distribution itself — it stays free forever.
Worse results with a paid tier, or fake rate-limit asterisks — the free tier uses the same data and the same engine.

Self-hosting = “Indie” plan

git clone https://github.com/your-org/nsfw-scanner
cd nsfw-scanner
run.bat test          && run.bat db
run.bat serve --port 8099
# service site:
php -c packages/nsfw-website/_ini -S 127.0.0.1:8100 -t packages/nsfw-website/www

Above is fully FOSS. To keep it that way, contributions have to balance sponsorship of infra costs — which is exactly what the paid plans pay for.
