SideButton
Your AI coding agents, working as one team, 24/7
SideButton turns the AI coding agents your team already uses into one coordinated engineering team.
Today every agent needs a human babysitting it, so 10 agents don't give you 10x. SideButton runs a fleet of role based agents (frontend, backend, QA, senior review) that work together on their own VMs, steered through Jira /Linear and GitHub. Drop a ticket or epic, and the fleet builds it, reviews it, tests it on a live environment, and ships a merged PR. You're back only to verify, or when a gate needs a human.
What makes it different:
- One team, not a mob: hierarchical roles with an independent senior-review gate, so quality rises as you scale.
- Runs on your own cloud, on any model (Claude, Codex, Bedrock, Vertex, self-hosted). Nothing locked in.
- Your agents learn your systems and keep that knowledge in your own repo, getting sharper every week.
- Open source core: spin it up with npx sidebutton.
- Built for engineering teams that want more output at higher quality, without babysitting a swarm of agents.
- Built on an open MCP server: works with any MCP client (Claude Code, Cursor, Claude Desktop) out of the box.
Features
- Role based agent teams: Compose PM, frontend, backend, QA and senior review agents that work together, each on its own VM.
- Playbooks: Encode a workflow once; every ticket runs the same way, from ticket to merged PR, with full context handoffs.
- Senior review gates: Nothing merges without an independent review plus a live environment test, so quality rises as you scale.
- Self learning knowledge packs: Agents document how your apps work and keep that knowledge in your own repo, getting sharper every week.
- Runs on your own cloud, any model: Bring your own cloud and LLM (Claude, Codex, Bedrock, Vertex, self hosted). Your code never leaves your perimeter.
- Live fleet monitoring: Tail every agent's screen, progress and cost in real time, and step in any moment.
- Open source MCP server: Run npx sidebutton and plug it into Claude Code, Cursor or Claude Desktop over MCP: real browser control, a workflow engine and installable knowledge packs for any agent. Upgrade to the Portal to run fleets.
Use Cases
- Ship features end to end: Turn a Jira ticket into a reviewed, merged PR across frontend, backend and QA, without a human on every step.
- Clear your backlog: Point a fleet at your bug and ticket backlog and let it run 24/7.
- Automated live QA: A QA agent tests every change in a real browser on the live environment before it merges.
- Scale output without hiring: One product lead or engineer directs a whole team of agents.
- Onboard agents to your stack fast: Skill Discovery learns your systems, so new agents are productive from day one.
- Keep everything in your perimeter: For regulated or EU teams: run the whole fleet in your own cloud, on your own models.

Hey everyone, We built SideButton because working with AI coding agents had quietly become a full-time job. At our previous startup, every agent needed a human babysitting it, so more agents just meant more chaos, not more output. So we built an orchestration layer that runs a whole team of agents (frontend, backend, QA, senior review) as one coordinated unit: you drop a Jira ticket, and the fleet builds, reviews, tests and ships it, with a senior review gate so nothing bad merges. It worked so well internally that it was too good to keep to ourselves. It runs on your own cloud, on any model, and the core is an open source MCP server you can spin up with npx sidebutton. Would love your feedback, especially from teams already running agents at scale. Happy to answer anything in the comments.
