Our verdict on Signater
Signater is a cloud-based electronic-signature platform for businesses that send, authenticate, track, and store signed documents. It is aimed at developers and teams that need programmable envelope workflows, configurable signer validation, document retrieval, and branded signing experiences. Its REST API covers envelope creation, document uploads, signer configuration, workflow tracking, and retrieval of signed files and audit certificates. Signing is available through web, API, iOS, and Android, with sequential or parallel flows, templates, vault-based organization, and mobile-browser signing.
The plan structure ranges from a limited free tier to enterprise resale features. Free includes 3 envelopes per month, 1 user, legally binding ESIGN and eIDAS signatures, real-time notifications, and selfie authentication. Starter costs $39 per month monthly or $23 per month with annual billing, and adds 30 envelopes, unlimited users, templates, QES, automatic reminders, and scheduled publishing. Business costs $79 monthly or $47 monthly annually, with 30 envelopes, unlimited users, advanced selfie with liveness, facial biometrics, signer data collection, integration API, and webhooks. Enterprise costs $499 monthly or $299 monthly annually, raises the allowance to 200 envelopes, and adds white label, OIDC single sign-on, managed accounts for resale, and priority chat support.
Signater fits products that need identity-aware signing and lifecycle automation. Business and Enterprise provide the API, webhooks, and sandbox needed for integration work, while email, SMS, WhatsApp, and OIDC support broader delivery and access patterns. The platform also offers white-label domains, branding, email sending, and managed accounts, making Enterprise relevant for resale or embedded signing services. The main constraint is plan gating: developers needing API access must choose Business or Enterprise, while teams with light, user-facing signing needs may find the Free or Starter plans sufficient. Choose Signater for programmable workflows, identity validation, or branded deployments; look elsewhere if API access is required at a lower tier.
