Project & roadmap command deck

All your projects. One ranked deck.

Threlmark is a local-first hub that manages every project in one place and runs a scored, kanban-style roadmap for each. Your data is plain JSON on disk — so your other tools can read a roadmap and write suggestions straight back into it.

No cloud · no accounts · no database · your data never leaves your machine.

What you get

One hub for every roadmap

The ranked kanban you already love — generalized across all your projects, with the data open on disk.

Multi-project hub

Create, switch, and archive projects. A cross-project Portfolio ranks the top work everywhere by status-weighted priority.

Ranked kanban

Four lanes, drag-between-lanes, and a 1–5 score on impact, evidence, fit and effort that computes a single priority.

Inbox for suggestions

Other tools drop a JSON file; it appears in the Inbox. Accept it into a roadmap item — or promote it into a different project.

Handoff briefs

Turn selected cards into a file-scoped Claude/Codex implementation prompt — with acceptance checkboxes and verification commands — or Markdown / JSON.

Cross-project links

Move items between projects, mark dependencies, or refactor duplicated work into one shared item used everywhere.

Open data on disk

Plain JSON under ~/.threlmark. Inspect it, back it up, sync it, and let any tool read or write it directly.

How it works

Disk is the source of truth

The layout on disk is the contract. The app and your other tools share one path to the same files.

Score & rank

Add cards, score them on four axes, and let Threlmark compute priority and float in-flight work to the top.

Interoperate

Each project is a folder of JSON files. Another app reads the roadmap or drops a suggestions/*.json with a single write.

Hand off

Select what's ready and export a precise implementation brief for Claude or Codex — acceptance criteria and verify commands included.

Local-first, and yours

No cloud, no accounts, no secrets. Threlmark runs on your machine and keeps every roadmap as plain JSON you control — readable, portable, and crash-safe.
