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. Pull in open GitHub issues too. Accept any of them 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.
Flow, not just status
WIP limits, work-item age and stale flags, plus a Flow tab with throughput and cycle time — manage how work flows, not only where it sits.
Initiatives & bulk push
Tag cards with a label and it becomes a trackable initiative with live progress. Filter to it, Select filtered, and Push N → Development to move a whole theme at once. See how →
Agents close the loop
Hand off the whole Development lane to Claude or Codex in one click. The brief tells the agent to report back — a “done” report moves the card to Done by itself and records what was built. See the flow →
Import from anywhere
Bring an existing roadmap in three ways: the original roadmap.html, a Trello board export (lists become lanes), or GitHub issues. Re-importing updates instead of duplicating.
Dates, notes & decisions
Schedule a start and a due date — overdue cards get flagged. Add comments and decision records to any item, and read a derived activity timeline of everything that happened to it.
Insights: risks & forecasts
A live risk register (overdue, stale, WIP breaches, stalled handoffs, bottlenecks — each with a suggested action) plus a Monte Carlo completion forecast from your real throughput. Per project and across the whole portfolio.
Built for every vertical
Start a project from a vertical template — software, marketing & content, business ops, research & trading, compliance — or define your own categories. Saved views keep each team's slice of the board one click away.
MCP, webhooks & automations
A built-in MCP server gives agents the whole board as native tools — read the plan, move cards, report back, propose work into the Inbox. Webhooks and simple rules let every event drive the rest of your stack.
Plan my day & weekly digest
One risk-aware queue across every project tells you what to do next — and says why. At week's end, a generated digest shows what shipped, what started, what's at risk, and when the rest will land.
⌘K everything & snapshots
A command palette searches items, decisions and outcomes across all projects and jumps straight to the card. Need to share? Export any board as a single read-only HTML file — no app required.
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 & auto-close
Export a precise brief for Claude or Codex. The agent builds it and reports back — a “done” report moves the card to Done by itself.
Works with IdeaClyst
Because the disk layout is a shared contract, other local-first tools plug straight in. IdeaClyst — an idea engine — is the first.
Reads your roadmap
IdeaClyst reads a project's roadmap (read-only) and finds the gaps — which categories and lanes are thin.
Writes back suggestions
It proposes scored Features, Spin-offs and Services — grounded in live web research — straight into your project's Inbox.
You close the loop
Accept & rank it, hand it to an agent, it ships and reports back to Done. The shrinking gaps shape what IdeaClyst proposes next.
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. Light or dark, your call.
