The short version

  • Each has a real cost: Prisma prisma Postgres is billed per operation, with the free tier at 100,000 operations and 500 MB of storage; ReadMe pricing is per project, so an organisation with several distinct APIs multiplies the monthly bill rather than adding seats, and the sensible workaround, merging unrelated APIs into one documentation project, distorts the information architecture to fit the invoice.
  • They diverge on capability: Prisma covers ORM, ReadMe covers OpenAPI reference.
  • Prices and features above were last checked on 30 August 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Prisma

  • Prisma Postgres is billed per operation, with the free tier at 100,000 operations and 500 MB of storage
  • Starter at $10 a month includes 1M operations then charges $0.0080 per 1,000
  • Storage overage runs from $2.00 per GB on Starter down to $1.00 per GB on Business, so the unit cost depends on the plan
  • Accelerate charges separately per operation and per GiB of query egress beyond the first 1 KiB
  • Cache tag invalidations are not included below the Pro plan and are billed per thousand above it

ReadMe

  • Pricing is per project, so an organisation with several distinct APIs multiplies the monthly bill rather than adding seats, and the sensible workaround, merging unrelated APIs into one documentation project, distorts the information architecture to fit the invoice.
  • The metrics and personalisation features require your API to stream request logs to ReadMe, which means production request metadata leaves your infrastructure and needs a scrubbing layer plus a security review before anything is switched on.
  • Single sign-on and private documentation sit on the higher tier, so a company that only needs to gate partner documentation behind SAML pays a large step up for one control.
  • The platform is built for describing REST APIs, and long-form product manuals, internal knowledge bases or non-OpenAPI protocols fit it badly, so most customers end up running a second documentation tool alongside it.
  • Theming is bounded by ReadMe templates and limited custom CSS, so a documentation site that must match a strongly designed marketing site will not get there without compromise.
  • Content uses ReadMe-specific Markdown extensions and platform features, so migrating away is an export plus a rewrite rather than moving a folder of Markdown files.

Answered from the vendors’ own pages

Prisma: How much does Prisma cost?

Prisma is free to start with 1M requests/month. The Starter plan costs $10/month with 5M requests, the Pro plan $49/month with 20M requests, and the Business plan $129/month with 100M requests. All plans have usage-based overages.

Source
ReadMe: Is ReadMe priced per user?

No. It is priced per project, meaning per documented API. Team size does not change the bill, and a second API generally does.

Prisma: What is Prisma's overage pricing?

Prisma charges $1 per million requests over the included amount (Starter), $2 per million database operations overage (Pro and Starter), and $1.50-$2 per GB for storage overages depending on the plan. All plans include a hard spend limit on by default.

Source
ReadMe: Do I have to send my API logs to ReadMe?

Only for metrics and personalised documentation. The reference, guides and playground work without it, but the features that most distinguish the product are the ones that need the log stream.

Prisma: Does Prisma include data transfer costs?

No, Prisma includes unlimited data transfer with no egress fees on all plans. Prisma ORM remains free across all tiers.

Source
ReadMe: Can I keep documentation in Git?

Yes. The rdme command line tool synchronises Markdown and OpenAPI files from a repository, so documentation can ship in the same pull request as the code.

ReadMe: Can I self-host it?

No. ReadMe is a hosted product only, so buyers with a hard on-premises requirement need a different platform.
