Rawkit – Free, no-ads developer tools that run in the browser
Hey HN, I built rawkit.dev, a collection of browser-based developer utilities. No ads, no signups, no tracking. Everything processes client-side — your data never touches a server. The tools: - JSONForge: JSON editor with tree/graph views, diff, transform, JQ-style queries, format conversion - SQLSandbox: SQLite via WASM — import CSVs, write SQL, join across files - Regexplorer: Regex builder with live matching, plain English mode,nmulti-language export - SiftLog: Log file viewer with auto-detection, severity filtering, regex search, timeline - Tabulate: CSV/TSV viewer with…

Hey HN, I built rawkit.dev, a collection of browser-based developer utilities. No ads, no signups, no tracking. Everything processes client-side — your data never touches a server. The tools: - JSONForge: JSON editor with tree/graph views, diff, transform, JQ-style queries, format conversion - SQLSandbox: SQLite via WASM — import CSVs, write SQL, join across files - Regexplorer: Regex builder with live matching, plain English mode,nmulti-language export - SiftLog: Log file viewer with auto-detection, severity filtering, regex search, timeline - Tabulate: CSV/TSV viewer with spreadsheet-style filtering and sorting Tech: Vanilla HTML/CSS/JS. No frameworks, no build step. Each tool is essentially 3 files(index.html, css and .js file) I built these because I was sick of ad-ridden, upload-your-data-to-our-server alternatives for tasks I do daily. The goal is to keep adding tools that developers actually need. Curious what tools you'd want to see next
