Your APIs don't stop needing testing when you step away from your desk. API Canvas brings a full-featured, native testing experience to iPhone and iPad—built from the ground up on Apple's Liquid Glass design language, not bolted onto a web wrapper. With API Canvas in your pocket, you have access to: ▶ Send Requests: Make HTTP calls using GET, POST, PATCH, PUT, or DELETE methods. ▶ Inspect Responses: Response bodies and headers are made easy to read and understand. Syntax highlighting makes HTML and JSON responses easy to read, even in dark mode. ▶ Stars & Collections: Mark your requests as starred or add them to a collection of your choice to make them easy to find. ▶ Import Requests: Bring in your request collection from Postman so you're not starting from zero. ▶ Request History: Your most recent requests can be found with the touch of a button. Re-run them at any time. Go Pro to unlock: ▶ Customize Collections: Bring your collections list to life by coloring each collection and adding an icon that suits your personality. ▶ Environment Variables: No need to update the auth token in every saved request when it changes. Write 'Bearer {{token}}' once, and update it across every request. ▶ Export Requests: Package up your API requests into a tidy little JSON file and send it over to Postman or keep it as a backup just in case. You worked hard to build your web service. Your APIs deserve a testing tool that works just as hard. ---- Privacy Policy: https://canadiancat.io/api-canvas/privacy Terms & Conditions: https://canadiancat.io/api-canvas/terms

Handsfree turns your iPhone into a voice and text client for the coding agent on your computer. Talk to Claude Code or Codex, hear its replies, approve its actions, and keep your projects moving — hands-free, from anywhere. The voice is unlimited — no usage caps, and it's transcribed entirely on your device. Your agent runs where it always has: on your own machine. Handsfree connects to a small open-source "bridge" you run on your computer (over your Wi-Fi or Tailscale), so your code and conversations stay yours — nothing passes through our servers. CODE WITH YOUR VOICE Turn on voice mode and just talk. Handsfree transcribes your speech on-device and reads replies back to you, so you can steer a coding session while you're away from the desk, on a walk, or making coffee. STAY IN CONTROL Your agent asks before it acts. Approve, deny, or allow-for-the-session right from your phone — and answer the questions it raises along the way. ALL YOUR WORK, ONE TAP AWAY Jump between projects and sessions — across Claude Code and Codex — without losing your place. Pick up any conversation exactly where you left it. PRIVATE BY DESIGN • No account, no sign-in. • Speech is transcribed on your device. • Your messages go straight to your own computer, never to us — we run no servers. • The companion bridge is open source. GETTING STARTED 1. Install the bridge on your computer: npx handsfree-bridge 2. Put your phone and computer on the same network (or use Tailscale). 3. Scan the QR code the bridge shows. That's it. Handsfree is free. An optional tip supports development.
