Comparison
Sesori vs Cosyra
Cosyra gives you a per-user Ubuntu 24.04 container on Azure, pre-installed with Claude Code, Codex CLI, OpenCode, and Gemini CLI, plus iOS, Android, and web clients to drive it. Sesori takes the opposite approach: keep your real dev environment on your own laptop, and use the phone as a remote cockpit through a local bridge. The right pick depends on whether you want your code to ever leave your machine.
TL;DR
If you want to code from your phone without your laptop being on, Cosyra is the easier path because compute lives in the cloud. If you want your code, repo, and AI session to stay on your own machine, Sesori is the better fit.
Side by side
| Feature | Sesori | Cosyra |
|---|---|---|
| Where the code runs | On your own laptop. The bridge attaches to your local AI session. | In a per-user Ubuntu 24.04 container on Azure. iOS, Android, and web clients drive it. |
| Laptop must be on | Yes. The bridge runs alongside your local agent. | No. The container keeps running in the cloud. |
| Agents supported | OpenCode today. Claude Code, Codex, and others on the roadmap. | Claude Code, Codex CLI, OpenCode, Gemini CLI, all pre-installed in the container. |
| Privacy model | Code never leaves your machine. Relay only sees opaque encrypted traffic. | Code lives in a third-party cloud container. Standard cloud trust model applies. |
| Pricing | Open-source bridge today. Pricing announced as the product matures. | 1-hour free trial. Pro: USD 29.99 per month or USD 300 per year. |
| Persistent storage | Whatever your laptop has. Your existing repo, tooling, env vars. | 30 GB persistent storage inside the container. |
| Best for | Devs who want phone access to their real dev environment. | Devs who want a phone-only workflow without depending on a laptop being awake. |
Which one is right for you?
Pick Sesori if you
- You want your code, repo, and AI session to stay on your own machine.
- You already have a real local dev environment and do not want to mirror it.
- You care about a relay that only sees encrypted traffic.
- You are comfortable leaving your laptop powered while you code from your phone.
Pick Cosyra if you
- You want to code from your phone without your laptop being on.
- You do not mind your code living in a third-party cloud container.
- You want a single pre-installed environment that "just works" with multiple agents.
- You are happy with a clear monthly subscription for compute.
FAQs
No. Sesori does not host code or run AI sessions in the cloud. It is a mobile cockpit for AI coding sessions running on your own laptop. Cosyra is fundamentally a cloud sandbox with a mobile UI on top.
Cloud-hosted dev environments are easier for some workflows, but they move your code, tokens, and AI session into a third party's infrastructure. For developers who care about that boundary, or whose work involves repos they can't put in a vendor container, Sesori's local-first design is a closer match.
Today Sesori supports OpenCode. Claude Code, Codex, and other agents are on the roadmap. Cosyra ships a Ubuntu 24.04 container with Claude Code, Codex CLI, OpenCode, and Gemini CLI pre-installed, so it currently covers more agents out of the box.
Cosyra is a subscription because you are renting compute. Sesori's bridge is open-source, and pricing will be announced as the product matures. There is no cloud compute to pay for, because the work happens on your laptop.
Nothing stops you. Some developers use a cloud sandbox for throwaway prototypes and keep production repos local. Sesori targets the second case.
