The short answer: OpenSign™ is free contract signing software that lets you send contracts for signature, collect signatures from multiple parties in order, reuse templates and keep a legally binding audit trail — all without a subscription.
What contract signing software should do
- Multi-party signing — route a contract to several signers, in sequence or in parallel.
- Templates — reuse your standard agreements without rebuilding them.
- Tracking — see who has opened and signed, and send reminders.
- Audit trail — a timestamped record for every party, for legal defensibility.
- Security — encryption and, ideally, the option to self-host.
OpenSign delivers all of these for free.

Are online contract signatures enforceable?
Yes. Contracts signed electronically are enforceable under the ESIGN Act, UETA and eIDAS. The audit trail — capturing identity, timestamps and consent — provides strong evidence if a signature is ever questioned.
