What it really is
Sightengine — API-first AI content moderation for images, video, text, and live streams.
Our take
Operation-based billing; advanced checks cost multiple ops each. Free: 2,000 ops/mo (500/day cap). Starter $29/mo: 10K ops. Growth $99/mo: 40K ops, 10 req/sec. Pro $399/mo: 200K ops. Overage ~$0.002/op. DB $99 aligns with Growth tier, not entry.
Best for
Marketplaces moderating user-uploaded images and video
Social apps needing real-time nudity and violence detection
Developers wanting REST API without bundled human review
Not good for
Teams needing turnkey trust-and-safety workflow dashboards
Non-technical users expecting a no-code moderation console
High-volume platforms without overage budgeting controls
Friction report
Time to value
Fast: API key and a few lines of code to moderate.
Scale breakpoint
Operation multipliers and overages surprise teams at scale.
Walled garden
Low: API returns scores; you own enforcement logic.
