problem tagline icon The Issue

Your agents need a home

Claude Code in one tab. Codex in another. Amp in a third. npm is maybe running. The queue worker crashed twenty minutes ago but nobody told you. You have nine terminals open and you can't remember what's running in any of them.

Tab roulette

Tab roulette

Something needs your attention. Is it terminal three? Five? You're clicking through all nine trying to find the one that's screaming. By the time you find it, another terminal has rung a bell.

Agents flying blind

Agents flying blind

Your AI agent can't see your process output. It doesn't know your dev server crashed ten minutes ago. It's generating code against a stack that isn't even running. Garbage in, garbage out.

Is it even running?

Is it even running?

You're running three agents and a full dev stack. Green? Red? Running? Crashed? You have no idea without checking each terminal one by one.

solution tagline icon The Fix

One window. Every agent. Full visibility.

Run any CLI agent right alongside your dev stack. Solo auto-starts your stack, restarts crashes, and gives your agents visibility into your logs and process state via MCP.

What Solo actually does

Runs your agents and your dev stack together. No bloat, no configuration rabbit holes.

Start your agents and stack at once

Start your agents and stack at once

Add Claude Code, Codex, Gemini, Amp, whatever agents you need. Define your dev stack and hit play. Everything spins up together. When you're done, shut it all down with one click.

No more opening six terminals and trying to remember what this project needs.

Auto-restart when things crash

Auto-restart when things crash

Dev servers die. Solo notices and restarts them automatically. Set up file watchers so code changes restart the relevant process too.

Your AI agent won't generate code against a server that silently crashed 20 minutes ago.

See everything at a glance

See everything at a glance

Green means running. Red means crashed. See your agents and your entire dev stack in one dashboard. No clicking through terminals or guessing.

If something's wrong — agent or process — you'll see it.

Built for teams

Built for teams

Commit your solo.yml to the repo and everyone gets the same stack — including which agents to run. No more outdated READMEs or Slack messages asking how to set up the project.

New teammate? They're running the same agents and stack in minutes.

solution tagline icon Why Solo

Built for agentic development

Your agents need a reliable environment. Solo gives them one.

Image

Your agents can see your stack

Solo speaks MCP. Your AI agents can read logs, see process status, and restart crashed services — without you lifting a finger. Context-aware agents write better code.

Run any agent. No lock-in.

Claude Code, Codex, Gemini CLI, Aider, your own scripts — if it runs in a terminal, it runs in Solo. No built-in models, no vendor lock-in. Use whatever agent is best for the job.

Image

Interactive terminal

Type directly into running agents and processes. Respond to Claude's prompts, interact with your Rails console, or attach a debugger — all without switching windows. Smooth rendering with full ANSI support.

Image

Command palette & keyboard navigation

Everything in Solo is accessible via keyboard. Open the command palette, jump between projects, start and stop processes.

Share Solo with your team

Check in your solo.yml and give your team a shared source of truth — including which agents to run and how. Everyone gets the same dev environment in seconds.

25MB. Not another IDE.

Built with Tauri, not Electron. Solo is a lightweight dashboard, not a 500MB IDE replacement. It runs your processes and gets out of the way. Your editor stays your editor.

solution tagline icon Quality of Life

Small things that add up

Details you'll appreciate every day. Polish that shows someone actually uses this.

MCP integrations

Solo exposes your processes, logs, and project state to AI agents via MCP. Let Claude or other AI tools help debug and manage your stack.

Open in your editor

Set your default editor and open any project directly. One click to VS Code, Zed — whatever you use.

Lightweight & fast

Built with Tauri, not Electron. Around 25MB download. Uses less RAM than a single Chrome tab.

Security first

If your solo.yml changes after a git pull, Solo asks you to confirm before running anything. No surprises.

Frequently asked questions

How is this different from Warp?

Warp is a terminal replacement with a built-in agent. Solo is a lightweight dashboard that runs any agent alongside your dev stack. No built-in editor, no lock-in. If you like your terminal, keep it. Solo manages what runs inside it.

Does Solo use my agent API keys?

No. Solo just runs your local CLI tools and lets you interact with them. However you have your agents set up on your machine is exactly how they'll work inside Solo. Your keys, your config, your auth. Because Solo never touches your API keys or agent accounts, there's no risk of getting flagged or banned by any provider.

What platforms are supported?

Mac now, Windows and Linux coming soon. Solo is a Tauri app. Small, fast, and uses your system's native webview.

What happens when I close Solo?

All processes stop — agents and dev stack alike. Solo is your dev environment. When you're done working, close it and everything shuts down cleanly. No orphaned processes running in the background.

Can I share configs with my team?

Yes. Commit your solo.yml to your repo and everyone on the team can spin up the same stack.

Can I move a process between local and shared?

Yes. If you create a process locally and want to add it to your solo.yml, that's one click. Same if you want to take a shared process and make it local.

Is there a free trial?

The free tier is the trial, except it never expires. You get 3 projects and up to 12 processes total. Use it as long as you want.

Why pay when free tools exist?

Because Solo is a joy to use. No config files to maintain, no manual restarts, no juggling terminal tabs. MCP integration so your agents can see your logs, desktop notifications when things crash, and a UI that actually looks good. Free tools work. Solo delights.

Can I use my license on multiple machines?

Yes, up to three machines per license.

Does Solo collect any data or phone home?

We use Aptabase for privacy-first analytics. Basic usage stats only. We never send project names, process names, or anything about your code. Solo also checks license data to validate paid accounts. That's it.

Who made this?

Aaron Francis, creator of faster.dev. I built it because I was running Claude Code alongside my dev stack and juggling nine terminal tabs. Now I don't have to.

Can Solo run Claude Code / Codex / Gemini CLI?

Yes, any CLI agent that runs in a terminal runs in Solo. All the CLIs that exist today and the ones that will undoubtedly come out in the coming months, you can run inside of Solo from day one. No updating required.

Does Solo replace Docker?

No. Solo manages processes, not containers. If your workflow uses Docker, Solo runs alongside it. Add docker compose up as a process and Solo monitors it like anything else.

What if Solo crashes?

Solo tracks PIDs of all running processes. On restart, it detects orphaned processes and shows a dialog to kill or reattach them. No zombie processes eating resources in the background.

How does the security/trust system work?

Solo never auto-runs something you didn't add yourself. If your solo.yml changes (like after a git pull), Solo asks you to confirm before running anything. No surprises.

Can I keep some processes to myself?

Yes. You can define local processes that don't get committed to the repo. Your personal stuff stays personal.

How do updates work?

Updates are free forever. The only restriction on the free tier is the number of projects and processes you can have, not whether you get updates.

What are the limits?

Free tier: 3 projects, up to 12 processes total. Pro: unlimited projects and processes.

Does it work offline?

Yes. Solo validates your license once then caches it locally. You get a 14-day offline grace period before it needs to check in again. Your configs are plain text solo.yml files, portable and readable by anything.

Is there a dark mode?

Yes. Light mode and dark mode, plus a system option that follows your OS preference.

Is this a fork of VS Code?

Haha, no. Solo is a native Tauri app — 25MB, no Electron, no bundled Chromium running a text editor. It uses your system's native WebKit and does one thing well: run your agents and dev stack from a single window.
