JSON & Data
For cleaning, inspecting, and safely moving structured data around.
Encoding
For encoding text safely through URLs, logs, and transport layers.
Text Encode / Decode
Convert and debug text encodings in your browser: URL encode/decode, HTML entities, Unicode code points, JSON/JS string escaping, and charset byte views (UTF-8/UTF-16/Latin-1).
Base64 Encoder / Decoder
Encode or decode Base64 and URL-safe Base64 in your browser, with UTF-8 and padding control.
QR Code Generator & Reader
Generate QR codes from text or URLs, or decode them from image files — all in your browser.
URLs & Networking
For inspecting, debugging, and reshaping what goes over the wire.
URL Parser & Query Editor
Break down any URL into protocol, host, path, query parameters, and fragments — parsed instantly in your browser.
JWT Debugger
Decode and inspect JSON Web Tokens, understand header and payload, and see claims at a glance.
Tokens & IDs
For generating identifiers that are easy to paste and reason about.
Integrity & Security
For checksums, digests, and lightweight security helpers that stay inside your browser.
Converters
For quick, precise conversions between timestamps and human-readable dates — with timezone-aware output.
Timestamp ⇄ Datetime Converter
Convert Unix timestamps to human-readable datetimes with timezone, ISO 8601, and RFC3339 support. Runs entirely in your browser.
YAML ⇄ JSON Converter
Convert YAML to JSON and JSON to YAML with live parse errors and pretty-printed output.
Base Converter (2 · 10 · 16)
Convert between binary, decimal, and hex with BigInt support and a byte-order visualizer.
Code & Types
For turning JSON payloads into strongly-typed interfaces and quick code scaffolds.
API & HTTP
Lightweight, in-browser tools for poking at REST APIs and inspecting responses.
HTTP Request Debugger
Send GET, POST, PUT, and DELETE requests with JSON or form bodies, custom headers, and a live response inspector.
Swagger Doc Tool
Validate, canonicalize, diff, and preview Swagger/OpenAPI specs without leaving your browser.
Browser API Capability Scanner & Playground
Inspect which modern Web APIs your current browser actually supports, see permission status, and try them out in a safe, developer-focused playground. Perfect for PWA, H5 games, and Web SDK authoring.
Text & Patterns
For inspecting, validating, and wrangling text, logs, and patterns.
Schedules & Jobs
Understand and debug cron-like schedules without leaving your browser.
Designer Tools
For designers and developers working on UI/UX projects.
Birdor aims to stay small, predictable, and kind to your attention. More tools will arrive slowly over time—focusing on encoding, debugging, and everyday backend/frontend workflows.
If a tool becomes essential for you, consider mirroring the logic into your own codebase or CI so it's not tied to any single website.
