What Neon does that Fauna does not
Neon passes clear canonical domain, clear product positioning, llms.txt published, llms-full.txt / full agent docs, mcp discoverable, machine-readable metadata, structured api reference, authentication documented, self-service signup, cli available, mcp integration available, agent compatibility verified, and Fauna 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
Fauna fails clear canonical domain, clear product positioning, public docs discoverable, llms.txt published, llms-full.txt / full agent docs, mcp discoverable, machine-readable metadata, structured api reference, openapi / spec quality, authentication documented, request examples provided, response examples provided, errors and status codes documented, limits / constraints documented, self-service signup, no mandatory sales call, agent-compatible signup flow, programmatic credential creation, fast time to first request, copyable quickstart, cli available, mcp integration available, canonical workflow succeeds, structured, predictable output, machine-readable errors, retry behavior documented, idempotency support, rate-limit behavior predictable, observable execution, agent compatibility verified. Each one is a place an unattended run stops, which is usually what sends someone looking in the first place.
Where Fauna loses the points
| Pillar | Fauna | What it measures |
|---|---|---|
| Discover | 33 | 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 | 25 | Signup, keys, SDKs, and whether a human has to be involved. |
| Operate | 0 | Rate-limit headers, errors, status, and behaviour under load. |
Fauna is weakest on operate at 0/100. Missing rate-limit headers mean an agent finds the limit by hitting it. If that is the part your agent depends on, take the ranking above seriously; if it is not, Fauna may still be the right pick.
What an agent runs into with Fauna
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.
- Make signup self-serve; an agent cannot sit through a sales call.
- Ship an MCP server so agents can call you as a tool.
- Make docs reachable without auth or navigation gymnastics.
- 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.
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 Fauna") over the MCP server, or GET /v1/categories/databases.
