Software, built to last.

Raintree Forge is a small independent software studio. We design and build focused, durable productivity software — local-first applications that respect your time and leave you in control of your data.

What we build

Ensō

One calm place for your todo list, calendar, reading list, projects, and notes — offline-first, and synced across web, desktop, and mobile.

Todo — lists, subtasks, due dates, and recurring tasks.
Calendar — your events and deadlines together in one agenda.
Reading list — save articles from your browser and read them later, even offline.
Projects — plan work as a breakdown of tasks with a simple timeline view.
Notes — a page tree with a block editor, links between pages, and lightweight databases.
Vaults — end-to-end encrypted storage for the things that matter most.

Everything works without a connection. Changes you make on one device show up on the others as soon as they're back online — no manual merging, no lost edits.

Principles

Local first

Your data lives on your device and works without a server. Sync is a convenience layered on top, never a requirement to open your own files.

Yours to keep

Full export in open formats, anytime. Delete your account and it's gone. We don't sell data, run ads, or mine what you write.

Fewer, better features

We'd rather ship one thing that works quietly for years than ten that need attention every week. Stability is a feature.

Honest business

Straightforward subscription pricing funds the work directly. No investors to satisfy, no growth-at-all-costs, no dark patterns.

About

Raintree Forge was founded in 2026 as an independent, self-funded studio. We're a small team that designs, builds, and supports our software ourselves — the people who answer your email are the people who wrote the code.

We build for people who want tools that stay out of the way: fast to open, predictable to use, and still working the same way years from now.
