About Stagehand
Stagehand is Browserbase's open-source library for building AI agents on top of Playwright using structured actions.
It inherits Playwright's browser automation and adds structured methods — act, extract, observe, and agent — for AI-driven browsing, and it works across multiple model providers including OpenAI, Anthropic, and Google.
It's aimed at developers building browser agents who already work with Playwright and want model-agnostic structure. Two caveats: you bring your own API keys for the model providers, and browser-based automation is inherently slower than direct API integrations.
Against other browser-automation options, Stagehand's angle is layering AI agent primitives onto Playwright rather than replacing it, so existing Playwright knowledge carries over.

- Claude Code Memory
Claude Code has built-in memory — a CLAUDE.md file it reads each session — but it only holds short, hand-written notes. To make it understand a large codebase or docs set, you add a second brain: turn the repo into a knowledge graph, fold that into an Obsidian vault, and let the agent query the map instead of re-reading every file.

Claude Code can do most of your SEO — build a crawlable static site, write and optimize pages, fix the technical layer, even bottle the whole workflow into a reusable skill. What it can't do is invent authority or pick keywords, and if you let it generate 10,000 pages you'll get de-indexed, not ranked. Here's the honest, hands-on version for a maker whose site shipped last week.

The best vibe-coding tools aren't another AI model — they're the open-source Claude Code repos you stack on top of it. The right ones turn the agent from a fancy autocomplete into a disciplined senior engineer: it plans before it codes, designs properly, maps your codebase, and gets scanned for security. Here are eight worth installing.
