What Is Convex?
DatabaseConvex is a reactive backend-as-a-service: a TypeScript database with server functions (queries, mutations, actions), realtime subscriptions and built-in file storage and scheduling. Launched by former Dropbox engineers in 2022, it has become a popular backend for AI-built apps because its schema and functions are expressed entirely in TypeScript.
Detect Convex on any website:
Why Convex Matters
The database rarely shows itself in the browser, but the services wrapped around it (hosted backends, auth layers, REST gateways) do. Recognising Convex behind a site helps when you are evaluating a vendor's architecture, planning a migration, or checking whether a product's "serverless" claims hold up. We've fingerprinted Convex on 8 live sites in our database, so the answers here are grounded in real scan data — not marketing copy.
Does Convex Mean a Site Was Built With AI?
Convex says nothing about AI involvement.
A database service is an infrastructure decision. Human teams and AI coding tools deploy to the same providers, so the scanner records Convex as stack context only and it does not move the AI Influence Score in either direction.
How this feeds the score: builder fingerprints, bundle artifacts and AI-tool traces are weighed separately from stack context like frameworks, libraries and hosting. The full breakdown is on How scores work.
How Websites Using Convex Work
- Client connections to `<deployment>.convex.cloud` and `<deployment>.convex.site`
- `ConvexProvider` / `ConvexReactClient` in React apps with live-updating `useQuery` hooks
- Functions under /convex/ in the source, deployed with the Convex CLI
- Frequently chosen by AI coding assistants; weak supporting context only
Best Practices When Working With Convex
Based on patterns in our scan dataset and the detection evidence tiers.
- →Start by running a Convex detection scan on any URL you're evaluating — the 80+ signal engine returns a confidence score plus the exact markers it matched, which beats reading view-source by hand.
- →Cross-check the result against the full detection evidence in /how-scores-work — confidence tiers tell you whether a match is strong (headers + scripts) or circumstantial (a single HTML pattern).

How Our Detector Identifies Convex
Our scanner analyzes multiple layers of a website's technical fingerprint to detect Convex usage.
- Script URLs or inline script content matching "convex.dev", "convex.cloud" (high-confidence tier)
- HTML structure patterns such as "convex", "ConvexProvider" (medium-confidence tier)
- Signal weights for Convex: 90 points per high-tier match, 60 per medium, 30 per low — a site needs 60+ points before Convex is reported.

How do we detect Convex?+
Our scanner checks for these signals: Script URLs or inline script content matching "convex.dev", "convex.cloud" (high-confidence tier); HTML structure patterns such as "convex", "ConvexProvider" (medium-confidence tier); Signal weights for Convex: 90 points per high-tier match, 60 per medium, 30 per low — a site needs 60+ points before Convex is reported..

Ready to put Convex detection to work?
You now know what Convex is, why it matters, how to spot it, and where the detection signals come from. The next step is using that knowledge on a real URL — yours, a competitor's, or a prospect's.
