Check out superconductor.dev (I’m building it), if you want live app previews, docker-in-docker functionality, multiple agents in one mobile app, and more.
Our foundational design value was compute instance startup speed. We've made some design decisions and evaluated several "neocloud" providers with this goal in mind.
Currently, from launching an agent to that agent being able to run tests in our Rails docker-compose environment (and to the live app preview running), is about 30 seconds. If that agent finishes their work and goes to sleep, and then hours later you come back to send a message, it'll wake up in about the same time.
(And, of course, you can launch many agents at once -- they're all going to be ready at roughly the same time.)
> AFAICT, there’s no service that lets me: give a prompt, write the code, spin up all this infra, run Playwright, handle database migrations, and let me manually poke at the system. We approximate this with GitHub Actions, but that doesn’t help with manual verification or DB work.
- set up your environment any way you want, including using docker containers
- run any number of Claude Code, Codex, Gemini, Amp, or OpenCode agents on a prompt, or "ticket" (we can add Cursor CLI also)
- each ticket implementation has a fully running "app preview", which you can use just like you use your locally running setup. your running web app is even shown in a pane right next to chat and diff
- chat with the agent inside of a ticket implementation, and when you're happy, submit to github
(agents can even take screenshots)
happy to onboard you if that sounds interesting, just ping me at [email protected]
This is exactly why we built superconductor.dev, which has live app preview for each agent. We support Claude Code as well as Gemini, Codex, Amp. If you want to check it out just mention HN in your signup form and I’ll prioritize you :)
