About Ollastack
Ollastack provides a unified backend for handling form submissions, email mailboxes, and disposable inboxes for testing. It offers three core capabilities: headless form endpoints that capture submissions with geo-stamped metadata and spam filtering, real agent mailboxes for sending, receiving, and programmatically reading OTP codes, and CI-ready test inboxes for automated email verification. The service operates via a single API with OpenAPI specifications, allowing AI agents to interact with forms and mailboxes directly. Submissions are automatically tagged with location data including country, city, region, and timezone. Agent mailboxes support multi-tenant SMTP with automatic DKIM, SPF, and DMARC signing, enabling email delivery from custom domains. Test inboxes provide one-call polling for OTP extraction and deterministic assertions in CI pipelines.
