Grass gives your coding agent a dedicated VM that's always ready. No setup, no config, no burning your laptop. Point Claude Code or OpenCode at it and run. Monitor progress from your phone, steer mid-session, push changes, all without touching your machine. Every new account gets 10 hours free. No credit card needed.
We built Grass because we noticed something weird. We message our teammates from anywhere, on the train, at lunch, from the couch. But the moment we want to talk to our coding agent, we need a laptop and a terminal open.
That felt broken. Coding agents aren't tools you operate anymore. They're colleagues you work with. Grass is how you stay in touch with them.
What Grass does today:
→Thread continuity across your phone and laptop. Start a task on Claude Code or OpenCode on your machine, pick up the same conversation on your phone. Same context, nothing lost. → Free pre-configured VM. We sponsor 10 hours of Daytona compute. No credit card, no DevOps setup. Your agent has somewhere to work in under a minute.
→Bring your own API key. We never see it, never store it. Your keys stay on your device.
→Agent agnostic. Works with Claude Code and OpenCode today. More agents coming.
On security: Grass runs a BYOK architecture. Your API key never touches our servers. We're building for developers who care about this, because we're developers who care about this.
Why we made it free to start: Every developer running coding agents should be able to try cloud compute without a credit card form in the way. 10 hours is enough to have your first "my agent finished while I was away" moment. After that, you'll know if Grass is for you.
A bit about us: Raunaq previously built Elemential (enterprise infra, shipped to NSE) and has trained 3,000+ developers on AI agent infrastructure. Anil built the core architecture, real time sync, SSE-based event buffering for mobile reliability, and Daytona VM orchestration. I lead design and creative, everything around how Grass shows up in the world.
We'd love your feedback, especially on what agents you want us to support next and what your ideal mobile coding workflow looks like. We're in the comments all day.
Cool idea but whats the plan when a session just keeps going and burns through hours? Some kind of cap would be nice. Also what specs do the VMs have, Claude Code gets pretty hungry on larger projects ...
The "no burning your laptop" part sold me haha. Being able to just point Claude Code at a remote VM and watch it work from my phone sounds like the dream setup. How does the git integration work -- does it push directly to my repo or do I review a PR first?
The environment setup tax on coding agents is real. I waste so much time getting the right dependencies installed before the agent can actually do anything. How fast is the cold start?
Running a local coding agent usually ends up chewing through all my RAM and crashing my active dev environment. Spinning up a persistent VM specifically for this is a brilliant way to handle long-running background refactors. I would love to know if you offer pre-configured images for different agent frameworks out of the box.
I love the idea of having a dedicated VM to do work and maintain context. This sounds like having the claude code app, but running 24x7. What kind of VM is being generated and persisted in the background (i.e. EC2s, docker container etc?)
Best of luck on your launch day, I'm running mine as well! I'm using claude and will give this a try.
The BYOK architecture is the detail that matters most to me. I've avoided cloud agent tools specifically because I didn't want my API key sitting on someone's server. Good to see this addressed upfront rather than buried in the docs.
Congratulations on the launch. This looks like something I’d use. I use my agents from different places and it’d be cool to keep on developing from my mobile for example.
Hello!
Does this work if I'm not on wifi? Like can I actually check in on my agent from anywhere?
Okay the 10 free hours with no credit card is such a smart way to get people to actually try this. Most tools gate everything.
honestly the VM angle is secondary for me. the real unlock is async handoffs - start on desktop, check in from phone. I already do this mentally, I just hate the context switching to do it.
One of the coolest launch today for sure! Do you see Grass evolving into something like Slack for AI agents or more of an execution layer behind the scenes?
Congrats on the launch @sunnyjoshi + team! Looking forward to trying this. Any hints as when the App Store version is shipping?
How does your tool-execution approval flow work end-to-end in practice—what exactly triggers an approval, what context does the user see (command, diff, risk signals), and how do you prevent “agent stalls” when someone is away?
Very cool, does this mean I can finally touch grass? 😄
Jokes aside, how are you thinking about session continuity and memory when there’s a disconnect or the user switches devices?
Pretty cool launch guys! How does this differ than claude code remote control? Is it the fact that it's part of a hosted VM instead?
Interesting, how does it connect to the VM from iPhone? does it ssh or just a message relay?
Hey PH!
