What Paddle does that Lemon Squeezy does not
Paddle passes clear product positioning, llms.txt published, mcp discoverable, structured api reference, cli available, mcp integration available, and Lemon Squeezy 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
Lemon Squeezy fails clear product positioning, llms.txt published, llms-full.txt / full agent docs, mcp discoverable, structured api reference, openapi / spec quality, authentication documented, request examples provided, response examples provided, errors and status codes documented, limits / constraints documented, agent-compatible signup flow, programmatic credential creation, cli available, mcp integration available, structured, predictable output, machine-readable errors, retry behavior documented, idempotency support, rate-limit behavior predictable, agent compatibility verified. Each one is a place an unattended run stops, which is usually what sends someone looking in the first place.
Where Lemon Squeezy loses the points
| Pillar | Lemon Squeezy | What it measures |
|---|---|---|
| Discover | 60 | 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 | 62 | Signup, keys, SDKs, and whether a human has to be involved. |
| Operate | 35 | Rate-limit headers, errors, status, and behaviour under load. |
Lemon Squeezy 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, Lemon Squeezy may still be the right pick.
