About

Truthlocks helps individuals, businesses, and developers create and verify signed digital evidence. Proof Frame turns public statements into shareable proof pages with live verification and local file comparison. APIs and SDKs support record verification, machine identity, and signed AI action receipts. Signature validity, issuer assurance, revocation, and transparency evidence are separate checks; a valid signature does not establish that a claim is factually true. The hosted platform is proprietary, and public integrations have separate licenses. Organizations can issue signed records through hosted workflows, with operations billed by usage.

About

sproof is the European platform for digital trust, signature, and identity processes – built for organisations with the highest requirements for security, efficiency, and scalability. The solution combines six modular components and supports all eIDAS-compliant signature levels – from simple to qualified electronic signatures (QES) – as well as integrated identity verification for seamless, legally compliant end-to-end processes. At the core of the platform are sproof Sign for electronic signatures (SES, AES, QES) and sproof Ident for identity verification and qualified signatures. These are complemented by additional modules including: sproof Fastlane – Highly simplified digital flow for obtaining legally valid e-signatures, including form data collection. sproof Widget – Direct integration of eIDAS-compliant electronic signatures (FES, QES) into any applications or websites. sproof Validate – Automated verification of digital signatures. sproof eID-Hub – Connection to Europe

Pros & Cons from Real Users

Pros

  • A super simple integration into our workflows, understandable for everyone without much user training and, above all, a legally compliant, European alternative for digital signing!
  • Easy to use, easy to convince people to use, and makes life so much easier. Support works quite well.
  • Easy to use. Gives full information about the documents status. Clean solution eliminating hard copies.
  • Say I need to get a document signed by 20 people all over Europe with actual qualified electronic signatures to prove the validity of the contract. I just upload the document, add the email addressees of the people I need to sign and/or in what order and away it goes. My partners can sign without even needing to sign up to the service.
  • Awesome and intuitive UI. All my partners are able to sign within seconds and I can also style my own signature image.

Cons

  • Some smaller features (e.g. signing on behalf of) were missing, but the support team responded quickly.
  • I hate, how some people still refuse to work with this tool.
  • Not easily found through search engines like Google.
  • I'm just upset i didn't know about this sooner.
  • I trying to call the sproof support but I did not reach anybody. But after one hour had a call from sproof direct and they solved my issues within one hours.
