200 sharp developer & PC utilities in one fast browser bench.
Format JSON, convert Word → PDF, decode JWTs, test dead pixels, build GitHub Actions YAML, check WCAG contrast - all local in your browser. No account required.
Live: https://chisel-app.pages.dev
Landing page in light mode: sidebar with all 200 tools, search with Ctrl+Q, featured cards, and Mobile / Desk / File converter / GitHub bench sections.
Same home layout in dark mode - soft charcoal panels, accent green highlights, and the theme toggle in the top bar.
JSON Diff tool open: paste two JSON blobs side by side and get a path-by-path list of what changed (adds, removes, value updates).
cURL → fetch() converter: paste a cURL command from docs or DevTools and get ready-to-run JavaScript fetch() code with method, headers, and body.
A tool page in dark mode showing the full workspace: category crumb, tool title with help (?), favorites, theme switch, and the active editor panels.
Most “tool dump” sites are noisy, ad-heavy, or send your data to a server. Chisel is built like a developer workbench:
- 200 tools across API, crypto, text, GitHub, converters, design, and PC/display
- Runs in the browser - favorites & drafts stay on your device
- Ctrl+Q palette for instant jump
- First-visit help on every tool (what / how / examples)
- Light & dark themes
- Deployed on Cloudflare Pages with an optional API proxy for key checks
