Signater
Signater is a digital contract service that lets businesses send, sign and track agreements through a browser. An envelope can gather several documents and signers into a sequential or parallel process, ending with a completion certificate. Signers can be checked using passwords, email or SMS codes, selfies with liveness checks, identity documents, facial biometrics or geolocation. Reusable templates hold standard text, with fields for variable details and a new version for each edit. The REST API can create and track envelopes, send them, upload documents, use templates, and retrieve signed files and certificates; API and webhook access is limited to Business and Enterprise plans. Webhooks send envelope events by POST and retry automatically. Signater lists HTTPS/TLS, HSTS and AES-256 encryption among its security measures, and signed PDFs can include embedded PAdES signatures, hashes and timestamps. Signers open links on phones or computers without an account or app. The platform and signing flow support six languages. A free plan includes three envelopes monthly; paid plans start at $39/mo.
