About OpnForm
OpnForm is turning its V2 platform into an automation surface, one integration at a time.
OpnForm shipped V2 in June — a major release that added PDF generation, computed variables, form import from Typeform, Tally, Google Forms and Fillout, and a Free/Pro/Business/Enterprise plan system with self-hosted license gating. The three releases since have been almost entirely self-hosting repair: OIDC sign-in recovery, trusted-proxy handling, PDF template editors breaking under relative API paths. v2.3.0 is the first post-V2 release that adds capability rather than fixing it.
