What KitVerse helps you do
AI work is full of friction: pricey tokens, unaudited skills, tool sites that take your data. KitVerse is my answer — free AI & dev tools that run locally in your browser. No signup, no uploads, no paywalls.
Who KitVerse is for
Built for AI builders and developers: indie hackers shipping AI products, engineers working with LLM APIs and agents, prompt engineers, and anyone adopting agent skills who wants to audit them first. It's also for privacy-conscious users who need everyday developer utilities (formatters, converters, generators) without handing their data to yet another server. No account needed — open a tab and get to work.
About KitVerse from the developer
KitVerse.dev is a free, local-first toolbox of browser-based tools for AI builders and developers. Every tool runs entirely in your browser — no signup, works offline, and nothing you paste is ever uploaded or tracked.
The toolkit leads with AI workflow tools you won't find bundled elsewhere: a Skill Security Scanner that statically audits SKILL.md files, scripts, ZIP packages and skill links for malicious execution, data exfiltration, credential theft and prompt injection; a PUA prompt generator that pushes AI coding agents to exhaust every option before giving up; an API playground for testing REST, GraphQL, WebSocket, SSE and MQTT endpoints; tokenizer and RAG chunking playgrounds with real token counts; plus prompt engineering tools, model pricing comparisons, and a daily digest of new AI terms.
Alongside these sits a complete set of classic developer utilities — JSON/YAML converters, regex testers, encoders, hash tools, generators, formatters — making KitVerse a single privacy-respecting home for both AI-era and everyday dev work. Free forever, no credits, no premium tier.
