Where each one falls short

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

Pusher

  • The free Sandbox plan is capped at 100 concurrent connections, which is quickly outgrown by production apps.
  • Pricing jumps sharply between tiers (e.g. $49 to $99 to $299), leaving few options for teams with moderate but growing usage.
  • Priority support with faster response times costs an additional $3,000/month on top of plan pricing.

Redocly

  • Only as useful as your commitment to OpenAPI; teams without a maintained spec get little from it
  • The portal and governance features are paid, while the open-source renderer covers only reference rendering
  • Linting rules are another thing to configure and argue about before value appears
  • Narrower than a general documentation platform, by design

Answered from the vendors’ own pages

Source
Redocly: Is Redocly free?

The Redoc renderer and CLI are open source and free. The developer portal and governance features are paid, with pricing published on the vendor site.

Pusher: Can I change or cancel my plan?

Yes, customers can log into the dashboard and adjust their plan at any time, including upgrading, downgrading, or cancelling.

Source
Redocly: What does the linter do?

It enforces rules on the OpenAPI spec itself in CI — missing descriptions, naming, examples — so a poor spec fails the build rather than becoming poor documentation.

Pusher: How is usage metered?

Usage is measured by concurrent connections and messages per day; a message counts both the publish and each delivery, so publishing one message to 50 subscribers counts as 51 messages.

Source
Redocly: Do I need OpenAPI to use it?

Effectively yes. Without a maintained specification there is little for it to work with.
