Agentation alternative
The Agentation alternative your whole team can use
Agentation turns a developer's notes on their own React app into context for a coding agent. Skyelight does the same for everyone who reviews the work: designers, product managers and clients pin feedback on any site, in their own browser, and your agent reads it from one shared place.
Free plan. Reviewers are free on every plan.
Why teams switch from Agentation
Feedback from people who don't run the code
Agentation renders inside your app in development, so the person annotating is the developer running it. “Our PM wants to be able to add annotations” is an open request on its GitHub. In Skyelight, the PM, the designer and the client pin on the page in their own browser.
Any site, no code to add
Agentation needs React 18 or later and an npm package in your app. Skyelight's Chrome extension works on any web page, whatever it's built with, including sites you don't own. Add Skyelight Build to a Next.js, Vite, Remix, Astro or WXT app for the source file and line on every thread.
Threads that stay, in one place
Agentation keeps notes in your browser for 7 days unless you run its local sync server. Skyelight keeps every thread in a shared workspace until it's resolved, with replies, owners and a status, and a hosted MCP your agent signs in to from Claude Code, Cursor, Codex, ChatGPT or Gemini CLI.

When Agentation is the better choice
Agentation is the better fit if you're a developer working alone on a React app, you want your notes to stay on your own machine, and you don't need anyone else to give feedback. It's free for internal use, it needs no account, and its Forensic output adds computed styles for each element.
Skyelight and Agentation: common questions
Agentation is a floating toolbar for React apps. You add it as an npm package, click elements on your running app, write notes and copy them as markdown with selectors and positions for your coding agent. An optional local MCP server lets the agent read the notes directly.
Both turn clicks on a page into context a coding agent can act on. Agentation is a developer tool for your own React app on your own machine. Skyelight is for everyone who reviews the work: it runs on any site without code changes, keeps feedback in a shared workspace with replies and owners, lets clients pin without a developer setup, and connects to your agent through a hosted MCP.
Agentation says it's free for individuals and for companies using it internally. You need a commercial license to resell it as part of a product. Skyelight has a free plan for one project, with 25 agent threads a month; Pro is $29 a month with no thread limit.
Agentation's MCP server runs on your machine with npx, and the toolbar sends notes to it on localhost. Skyelight's MCP is hosted, so your agent signs in once and reads every thread your team and clients left, from any computer. You can also hand a thread off as investigate, plan or fix, and the agent replies on the thread when it's done.
No. The Chrome extension works on any web page, whatever it's built with. Skyelight Build is optional: add it to a Next.js, Vite, Remix, Astro or WXT app to stamp the source file and line onto every element, and to let reviewers pin without installing anything.
