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.
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.
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.
