Manage your bank
Add a seed or seedling with just a photo and a name — no Latin required. Note the year, how much you have, where it came from, germination tests. Search, filter, snap now and name later.
Your seed bank in your pocket
Keep and share traditional seeds and seedlings — offline, encrypted, no account.
Every traditional seed is a letter written by thousands of generations, passed from hand to hand. Tane helps people and seed-saver collectives keep a friendly inventory of their bank, decide what they offer, and share it locally — without a central intermediary that could control it, censor it, or be fined for it.
Tane (種, “seed”; from tanemaki 種まき, “to sow seeds”) is a local-first, decentralized app for keeping and sharing traditional seeds and seedlings. It works with zero network — and connects you to a neighborly seed-sharing network when you want it.
Publishing to app stores soon. Meanwhile, Tane is free software you can build and run today.
Where Tane is right now
The inventory works today: keep your seeds offline, encrypted, with no account. The neighbourly sharing layer (offers, messaging, trust) is being built now. Everything already works with zero network.
Yours, and only yours
Works fully offline. No account, no server, no trackers. Everything is encrypted on your device. Keep an encrypted backup and a printed recovery sheet to restore your whole bank on a new device.
Share, as it's always been done
Mark what you have spare to give away, swap or sell. Someone nearby finds it and contacts you — no middleman. Print a catalog of what you share to take to a seed fair.
A look inside
International by design
Right-to-left and non-Latin scripts are first-class. Here is the inventory mirrored for RTL.
Why Tane is different
- No center: no company can shut it down, censor it, or be fined for it.
- Anti-monopoly by design — sharing seeds multiplies the commons instead of depleting it.
- Spreads like a seed, person to person, with no server in the middle.
- Free software (AGPL-3.0). No ads, no commissions, no business model.
Questions
- Is it free?
- Yes. Free software (AGPL-3.0), no ads, no commissions, no data selling.
- Do I need an account?
- No account, no sign-up, no server. Your data stays on your device.
- Does it work offline?
- Fully. The internet only enriches it; everything essential works with no connection.
- Is it legal to share seeds?
- Giving and swapping between growers is broadly allowed; selling can be regulated. You are responsible for what you share — see the notice on seed legality. →
- What about my privacy?
- Data is encrypted on your device and only what you explicitly share ever leaves it. See the privacy policy. →
