What Neon does that Convex does not
Neon passes mcp discoverable, structured api reference, authentication documented, mcp integration available, and Convex fails them. That is the whole of the gap between the two scores, so if none of those matter to your agent the ranking above overstates the difference.
Why people look for an alternative
Convex fails mcp discoverable, structured api reference, openapi / spec quality, authentication documented, request examples provided, response examples provided, errors and status codes documented, limits / constraints documented, programmatic credential creation, mcp integration available, structured, predictable output, machine-readable errors, idempotency support, rate-limit behavior predictable. Each one is a place an unattended run stops, which is usually what sends someone looking in the first place.
Where Convex loses the points
| Pillar | Convex | What it measures |
|---|---|---|
| Discover | 87 | Can an agent find it at all: sitemap, robots, structured data. |
| Understand | 23 | Is there a spec, an llms.txt, a machine-readable description. |
| Adopt | 76 | Signup, keys, SDKs, and whether a human has to be involved. |
| Operate | 59 | Rate-limit headers, errors, status, and behaviour under load. |
Convex is weakest on understand at 23/100. Without a spec an agent has to guess at endpoints, and it guesses wrong. If that is the part your agent depends on, take the ranking above seriously; if it is not, Convex may still be the right pick.
What an agent runs into with Convex
These are the findings from the last audit on 2026-08-23. Each one is a place unattended software stops, which is the practical reason to look at the list above.
- Ship an MCP server so agents can call you as a tool.
- Publish MCP install instructions so agents can discover the server.
- Publish an OpenAPI spec so agents can generate a client.
- Flesh out the OpenAPI: paths, schemas, and descriptions.
- Document error responses as an enum in your OpenAPI.
- Let agents create API keys programmatically.
- Return X-RateLimit / Retry-After headers so agents pace themselves.
- Add request examples to your API reference.
What this category actually supports
Across the 22 products scored in Databases, query a sql database is offered by 73%, serverless database is offered by 23%, branch a database is offered by 9%. Anything under half is a gap you should expect to fill yourself whichever one you pick.
An agent can get this list directly: resolve("alternative to Convex") over the MCP server, or GET /v1/categories/databases.
