OpnForm

Key features

• Unlimited forms and submissions on every plan The free cloud tier collects uncapped responses with no per-response charges, which suits high-volume surveys and lead capture where metered competitors get expensive.[1][2]

• Conversational or classic layouts Respondents move through a Typeform-style one-question flow or a classic multi-page form, so one builder covers both completion-focused and dense intake scenarios.[1]

• Conditional logic and computed fields Follow-up questions adapt to earlier answers and calculations derive values from responses, so one form serves respondents who should see different paths.[1][2]

• Pre-fills and URL parameters Forms accept prefilled answers and URL-driven defaults, which shortens completion for known contacts and embedded placements.[1]

• Themes, brand colors, and custom domains Visual customization keeps forms on brand, with branding removal and custom domains on paid plans rather than the free tier.[1][2]

• Integrations, REST API, and webhooks Named connections include Slack, Discord, Telegram, Google Sheets, Zapier, and Stripe payments, with webhooks and a public API for anything else.[1][2]

• Form protections on paid plans Password protection, expiration dates, and captcha guard sensitive or time-boxed collection, while editable submissions and unique IDs aid administration.[1]

• Docker self-hosting with a Community edition A scripted Docker setup runs the core free for up to two users with OIDC SSO inside that limit, and an Enterprise license key unlocks more users and licensed features.[1][2]

Who will love it

• High-volume collectors on a budget Uncapped submissions on the free tier remove the per-response metering that makes metered incumbents costly for large surveys.[1][2]

• Teams that need data ownership The Docker self-hosted Community edition keeps responses in infrastructure the team controls under an AGPL-3.0 core.[1][2]

• Builders of branded respondent flows Conversational or classic layouts with themes, logic, and integrations cover lead capture, registration, and feedback without custom development.[1]

Who should avoid it

• Teams with no operations capacity Self-hosting needs Docker setup, environment configuration, and reverse-proxy work, so purely hosted buyers should price the cloud plans instead.[1]

• Buyers needing enterprise controls on day one SAML and LDAP SSO, audit logs, and SLA support sit on the Enterprise plan, not the free or entry tiers.[1]

• Offline or non-web collection needs No documented offline respondent support was found, so field collection without reliable connectivity is out of evidenced scope.[1][2]
