How Sprint Engine works.

  1. A plan becomes a graph

    The architect splits a plan into tasks with dependencies, owners, and acceptance criteria.

  2. The engine takes the wheel

    Sprint Engine decides what unlocks, owns the concurrency, and drives first task to last.

  3. Specialists run in parallel

    The right specialist for each task, several tasks at a time.

  4. Epic in, shipped work out

    Hand it a whole-team epic; it runs to done, every step on the record.

What the work actually looks like.

Six columns — Todo, Ready, In Progress, In Review, Needs Input, Done — and a task’s column is derived from its dependencies, never dragged. Everything below came out of one markdown file, backlog/version-restore.md.

The board as the studio draws it — open a task, or answer the one waiting on you.

292 extensions, one click from any agent.

Curated MCP servers, skill packs, modules, and agent CLIs — each launches as an isolated chat or automation. Hand-picked from the HotStack index of 16,732 servers; the studio ships the curated set, not the index.

Extensions as it opens in the studio — add one and the counts follow.

The workspace you build yourself.

Every surface is a module and the SDK is public. This calendar is the benchmark: a full workspace built against the published SDK, outside our own repo.

Built on the Module SDK

Signed, verified, and installed like any first-party module — the same surface our own panels are built on.

First-class session manager

Your workspace spawns real agent sessions through the shared runtime.

Extensions and sprints included

Drop an automation on a calendar cell and it fires a real agent at that time.

Your backlog, live

Watch items in real time and hand back deep links.

Common questions.

Is SprintEngine Studio another AI IDE?
No — it is the local environment around your agents: terminals, files, Git, workspaces, extensions, and a knowledge graph.
Where does my code go?
Nowhere — it's a local desktop app. The only network calls are the ones your CLI agents already make.
Do I need a new AI subscription?
No — that's the point. If your terminal can run it, the studio can orchestrate it.
Can we build our own modules?
Yes — workspace types, providers, skills, and MCPs are all plugin surfaces, and the marketplace is the distribution path.
