Hamster

Collaborative product-planning workspace that turns briefs into structured tasks for AI coding agents.

Freemium· Free trial; paid tiers not publicly listedAgentsMulti-model (agent-agnostic)

Best for

Pick Hamster if your team is shipping with Claude Code or Cursor and needs a shared brief-to-task layer that keeps human intent in the loop.

Skip if

Skip it if you do not use AI coding agents, or if Linear/Jira plus a docs tool already cover your planning workflow.

Hamster is an AI-native product planning platform that sits between human decision-making and the AI coding agents that execute the work. Teams write structured briefs capturing product direction, reasoning, and constraints, then Hamster breaks them into tasks with acceptance criteria that Claude Code, Cursor, Codex, Gemini, or other agents can pick up and ship. A Hamster CLI embeds those briefs directly into the repo so the agent always has the rationale, not just the ticket.

It is aimed at founders and engineering teams who have moved past prompt-it-and-pray and want a layer of alignment before the agents start writing code. Real-time collaboration with live cursors and voting replaces sprint planning and story grooming, and two-way sync keeps GitHub, Linear, Jira, Notion, and Slack in step. A free trial is available; paid tiers are not publicly listed and likely follow a per-seat scale-up model.

The vendor emphasises a third-party security audit and a no-training-on-user-data stance, which matters for enterprises piping product strategy through it. It is agent-agnostic rather than tied to a single coding tool, which is the right bet given how fast that layer is churning.

Editor's take

Hamster targets the right gap: most agent failures are spec failures, not model failures. The agent-agnostic CLI-into-repo approach is smarter than vendors trying to own the editor too. Hidden pricing is the main thing keeping us from a stronger recommendation.
