The sync engine that treats the network as optional.

A true local-first ledger — commits on device, deterministic ordered replay, inspectable queue, permanent air-gap support. See the side-by-side comparison →

All of them — it is the platform underneath, not an add-on. AI Delta OS starts at ₹999/site/mo yearly (₹1,299/mo · $19/mo · ₹29,999 perpetual), Growth at ₹2,999/site/mo ($39/mo · ₹99,999 perpetual), Scale at ₹7,999/site/mo ($109/mo · ₹2,49,999 perpetual), and Enterprise runs the same engine sovereign or air-gapped. Per site, unlimited staff. Model it in the estimator →

Yes — air-gapped is a supported permanent mode: full local ledger, signed handovers for anything that must cross, and zero phone-home. Deterministic rules merge when sites do reconnect; nothing silently diverges.

One ledger — POS Terminal, Stock Transfers and Stock Audits read and write the same live stock, customer and fiscal rows, so switching each on just exposes capability that already shares your data. Zero webhooks, CSV sync or Zapier glue between them.

The engine ships under every plan — start on AI Delta OS or Growth and the offline ledger is already underneath you. Scale plans add a dedicated staging sandbox and a named implementation lead who walks the cutover. Start the guided trial → Book a demo →

Nothing. Checkout completes locally; the transaction queues for replay — same receipt, same ledger.

Deterministic rules per document type — reconciled edits merge, true conflicts surface for review.
