About Persona.js
Persona JS is a JavaScript library that adds AI chat to any frontend with a WebMCP-native implementation.
Its distinction is the WebMCP-native approach: it drops AI chat into a web frontend through a JS library rather than a hosted widget or separate service.
It's aimed at developers who can integrate a library into their own frontend. Two caveats: its WebMCP support depends on browser-side implementation that isn't yet broadly standardised, and the pricing model isn't publicly listed, so cost is hard to evaluate up front.
Among AI coding-agent tools, Persona JS is a build-it-in library for adding chat to your own site, rather than a standalone agent or IDE assistant.

- 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.
