Fix HTML, shape CSS, check SEO, prepare mobile UI, and finish web work — without token costs, accounts, or uploads. Each tool gives you a result you can inspect, copy, and use right away.
Why this exists
Deterministic output. No tokens. No hallucinations. Missing canonical tags, broken favicon paths, awkward mobile padding, and messy social previews need a reliable answer — not another chat session.
