Redocly vs Scalar
A side-by-side editorial comparison of Redocly and Scalar — release velocity, themes, recent moves, and the top alternatives to consider.
Redocly vs Scalar: at a glance
What is Redocly?
Redocly forks Markdoc and points Open in Claude at the desktop app.
Redocly's November 4 package release moved its docs stack to @redocly/markdoc, its own fork of Markdoc, with existing custom tags still working. The same release renders GitHub alert syntax as admonitions, sends Open in Claude to a Claude Code session in the desktop app, adds enum menus to the Try it console, and fixes mock servers that leaked earlier responses. The day before, config 0.71.0 made the docs agent opt-out.
What is Scalar?
Scalar's November 5 releases give each API document its own authentication settings
Scalar ships several package lines on separate version tracks. The November 5 API reference releases (1.77.0 and the ASP.NET Core 1.1.47) let each document carry its own authentication defaults, render specification extensions, and make search much faster on interconnected schemas. The mock server gained an onResponse hook and spec-correct path matching, and the API client hardened its CORS proxy against XSS and open redirects. The SDK generator now emits experimental signed-URL methods across ten languages and sends only the credentials each operation requires.

Redocly
6.3INFRA · APIS
Redocly forks Markdoc and points Open in Claude at the desktop app.
◆ Current state
Redocly's November 4 package release moved its docs stack to @redocly/markdoc, its own fork of Markdoc, with existing custom tags still working. The same release renders GitHub alert syntax as admonitions, sends Open in Claude to a Claude Code session in the desktop app, adds enum menus to the Try it console, and fixes mock servers that leaked earlier responses. The day before, config 0.71.0 made the docs agent opt-out.
◆ Where it's heading
Redocly is taking more of its stack in-house and renaming it around one platform: Reunite options become platform, mcp.docs folds into mcp, and Markdoc is now a fork. The AI hooks point at the desktop agents rather than web chats, which fits the opt-out docs agent shipped a day earlier.
◆ Prediction
Expect the deprecated reunite and mcp.docs names to become errors in a later config release, and more Markdoc tags only Redocly's fork supports.

Scalar's November 5 releases give each API document its own authentication settings
◆ Current state
Scalar ships several package lines on separate version tracks. The November 5 API reference releases (1.77.0 and the ASP.NET Core 1.1.47) let each document carry its own authentication defaults, render specification extensions, and make search much faster on interconnected schemas. The mock server gained an onResponse hook and spec-correct path matching, and the API client hardened its CORS proxy against XSS and open redirects. The SDK generator now emits experimental signed-URL methods across ten languages and sends only the credentials each operation requires.
◆ Where it's heading
The reference renderer is in a polish phase after October's localhost toolbar and hosting waitlist, while the SDK generator is where breadth is growing fastest. Signed URLs, idempotency keys and per-operation credentials show Scalar chasing parity with dedicated SDK vendors across many languages.
◆ Prediction
The hosting waitlist has gone quiet in these notes; the clearest near-term pattern is signed-URL methods leaving experimental status and reaching the remaining SDK targets.
