Migrations are capex events and enterprises want to own their tools. Hafen ships as signed license files that run inside your VPC — offline, no subscription, no phone-home, no vendor lock-in.
Parser + runner + CLI. MIT.
Full self-hosted install. No license.
Per-project license. 90 days. Offline.
Site license + air-gap install.
Pro and Enterprise ship as signed offline license files (JWT). Verified locally against a bundled public key, valid for the stated term, no network check required. A single successful migration typically recoups its license cost in Oracle savings within 90 days.
Migrations are one-time projects, not ongoing services. Buying a SaaS subscription for something you'll finish in 90 days wastes money and creates an awkward procurement story (“we still pay for the migration tool we finished using”). Pay once for the term you need.
The Pro features disable; Community features (parser, runner, CLI, web UI, assessment) keep working indefinitely. Migrations you already ran are done — the license term is about Pro features during the active project. Extensions are straightforward if you need them.
Correct. License verification is 100% offline. The JWT is signed with our private key; your install verifies it against a public key bundled in the image. We never see your DDL, your DSNs, or that you're running. That design is why regulated customers (finance, healthcare, government) approve us.
Oracle → PostgreSQL today. SQL Server, DB2, and Snowflake sources are on the roadmap. If you have a specific source and a real project, talk to us — we prioritize based on committed projects.
