Simple Dev Tools
Fast tools for everyday dev work.
Browser utilities from Jonathan R Reed for API snippets, diagrams, SQL, regex, IDs, QR codes, schemas, and tokens.
Each tool is built for the small checks that slow down implementation: formatting request examples, debugging regular expressions, sketching Mermaid diagrams, inspecting tokens, validating schemas, and keeping sensitive samples close to the browser.
API Snippet GeneratorDraft cURL, Python, and fetch snippets from one endpoint definition.Mermaid EditorSketch flows, sequence diagrams, and architecture notes with export tools.SQLite PlaygroundRun SQL experiments locally with SQLite WASM and instant result tables.Regex LabIterate on patterns with live matches, replacements, samples, and links.
