How does Customaise compare?

Honest side-by-sides with the products people already know. No marketing spin, no "we're better at everything." Each comparison ends with when to reach for which.

Tampermonkey

The same UserScript format, the same GM_* API, the same one-file install model. Customaise adds an AI editor on top so you describe the change in plain language and a Chrome MV3 engine so scripts persist across browser restarts. Tampermonkey if you want a battle-tested vault for handwritten scripts; Customaise if you want plain-language editing plus AgentScripts.

Claude for Chrome and Computer Use

Vision-LLM agents that pixel-drive any page. They work on every site but cost cents per action and take seconds per click. AgentScripts run as fast as a function call, cost a few hundred tokens, and read structured data instead of pixels. Use Computer Use for one-off long-tail tasks; use AgentScripts for repeatable workflows.

Playwright, Browser Use, Browserbase

Server-driven browser automation. Playwright runs locally or in CI; Browser Use and Browserbase are cloud agent-browser platforms. All three scale across machines but operate outside your signed-in browser, so they lose the cookies and 2FA your real session already cleared. AgentScripts run inside your browser, inherit your cookies, and reuse the session you already trust.

AI Browser (Atlas, Comet, Dia) and Claude Skills

The AI browsers ship a chat sidebar in their own Chromium fork. Customaise is the equivalent layer in the browser you already use. Claude Skills are markdown skill bundles users install directly from GitHub URLs; AgentScripts are the equivalent layer with editorial review on the marketplace and per-call consent at runtime.
