You need heavy anti-bot bypass or complex iframe navigation — browser-harness handles those better.
why it matters · browser-harness
Need Claude to log into something, scrape a page behind a paywall, fill out a form, or click through a real app? browser-harness spins up a real Chrome that Claude can control — screenshots, clicks, typing, iframes, popups, and it restarts itself if anything breaks. If you want your agent to actually do things on the web instead of just talking about them, this is the one. Free, open source.
why it matters · playwright (MCP)
Playwright is Microsoft's browser automation toolkit. The Claude Code integration lets your agent open a page, click, type, take screenshots, check the console, and handle popups — all with no setup. Every screenshot in the Armory build came from this — it's the go-to when an agent needs to verify a UI change. Simpler than browser-harness for most jobs — pick this one if you just need Claude to poke at your own local site. Free.
