Cosyra
A phone app that gives you a real Linux computer in the cloud with AI coding assistants already installed, so you can keep working — or fix a production issue — from your phone without a laptop nearby.

Description
Sometimes a bug happens right when you don't have a laptop — you're commuting, out for dinner, or just away from your desk. Cosyra is like keeping a spare computer running in a data center that you can reach into from your phone any time: it boots you into a full Ubuntu Linux environment with coding AI assistants already set up, and it stays exactly as you left it, files and all, the next time you connect.
Technically, Cosyra provisions a full Ubuntu 24.04 x86_64 container per user, pre-installed with four AI coding agents (Claude Code, Codex CLI, OpenCode, Gemini CLI), with 30 GB of persistent storage and — on the Pro tier — session hibernation so a stopped session resumes exactly where it left off. Native iPhone and Android apps handle the terminal interface; no server setup is required on your end. The free tier gives 1 hour of compute with no credit card, a Trial tier gives 10 hours over 7 days, and Pro is $29.99/month (or $300/year) for 120 hours of compute per month, billed through the App Store or Google Play.
💬 Our review
The short version: this is genuinely useful for on-call engineers who need to fix something from their phone at 2am, but at $29.99/month for 120 hours it's a real recurring cost for something most developers will use occasionally, not daily.
Against GitHub Codespaces or Gitpod, both of which also give you a cloud dev environment, Cosyra's differentiator is the native mobile app and pre-installed AI CLI agents — Codespaces and Gitpod are built for browser or desktop access, not a phone-first terminal experience. Against just SSH-ing into a cloud VM from a terminal app, Cosyra trades flexibility for convenience: less setup, but you're locked into their container image and pricing. The free 1-hour tier is a reasonable way to test whether phone-based coding is actually something you'll use before committing to a subscription — most people who try it once for a real incident will know quickly whether it's worth $30/month or a novelty.
