When Pastel fits better

  • You need client review on websites without adding any code or script tag.
  • You review static PDFs and images alongside website pages.
  • Your agency workflow relies on sharing canvas proxy links.

When pinthread fits better

  • You want a permanent free plan without archiving canvases to stay under a 1-canvas limit.
  • You want comments directly on live and staging builds, without canvas proxy rendering issues.
  • Your coding agent needs remote MCP tokens to resolve comments in the repository.

Switch from Pastel

  1. Sign up free and create a project for your site.
  2. Paste the script tag into your shared layout.
  3. Add each address where your site runs in the project's Settings.
  4. Point your reviewers directly to your site URL with the pinthread script tag instead of a Pastel canvas proxy link.
  5. Connect your agent. The agent guide has the setup for Claude Code, Cursor, and Codex.

Questions

Is pinthread free?

Yes. The Free plan costs $0 a month, needs no credit card, and includes every feature, with agent access over MCP.

Do reviewers need an account?

No. On a project with link access, reviewers can comment as a named guest. A guest name is not a verified identity. Owners can restrict a project to invited Google accounts.

How does pinthread compare to Pastel canvas links?

Pastel loads or proxies your website into a canvas link. pinthread embeds directly into your website via one script tag, so reviewers comment on your real running site without proxy rendering issues.

Can my coding agent read and resolve comments with Pastel and pinthread?

Yes. Both tools support MCP. Pastel connects Cursor, Claude, and ChatGPT. pinthread provides a remote MCP server at https://pinthread.dev/mcp with project-scoped read and write tokens on every plan, including Free.
