A flagship open-source product from the Qik family.
If DocuSign's per-envelope pricing and seat limits are holding your team back, OpenSign is the open-source alternative built for unlimited signing. Everything you expect — templates, audit trails, reminders, signing orders — without the metered bill.
Migrate your contract workflows to a platform you can self-host, customise and extend, while keeping signatures legally binding worldwide.
Key capabilities
No per-envelope fees
Stop paying for every document you send. Self-host OpenSign and send as many envelopes as you need.
Own your data
Keep contracts on your own infrastructure instead of a third-party cloud.
Fully customisable
Open source means you can white-label, theme and extend OpenSign to fit your brand and workflows.
Drop-in features
Templates, bulk send, reminders, signing order and audit trails — the essentials you rely on.
Why switch from DocuSign to OpenSign?
Most teams outgrow DocuSign's pricing long before they outgrow their signing needs. OpenSign removes the envelope meter so growing volume never means a growing bill.
And because OpenSign is open source, you are never locked in. Export your data, host it yourself, and adapt the platform as your requirements evolve.
