Overview
OpnForm is an open-source builder for forms, surveys and workflows. Fields are dragged into place, with conditional logic, calculations, computed fields, themes and either classic or conversational layouts, then shared by link, embed, Notion, custom domain or QR code. Responses route to Slack, Google Sheets, Zapier, Stripe and webhooks, and it runs on OpnForm's cloud, EU hosting or self-hosted.
- Best for
- Teams that need unlimited form responses and the option to self-host or keep data in the EU
- Pricing
- The Free plan is $0 with unlimited submissions and Pro, Business and Enterprise are paid cloud plans with 15% off yearly billing, but the captured pricing page shows $0 placeholders instead of their real rates; self-hosting is free for the Community Edition or $1,999/year per instance for the Enterprise licence.
- Runs on
- WebSelf-hosted

How this score is made up
Each dimension is scored out of 100 and combined into the headline score using fixed weights.
MCP support
Whether an agent can drive the product through the Model Context Protocol, and how much setup that takes.
API quality
Public API surface: machine-readable spec, official SDKs, documented auth, errors, rate limits and versioning.
Documentation
Publicly reachable docs — coverage, freshness, code samples and machine readability.
Agent friendliness
How readable the site is to an automated client: llms.txt, structured data, server-rendered content, crawler access.
Pricing transparency
Whether real prices are published, self-serve signup exists, and usage costs are knowable without a sales call.
Changelog
A public, dated record of what shipped and when — the clearest signal that a product is still alive.
Marketing site structure
Whether the site answers a buyer's questions: clear positioning, the pages that matter, and accessibility.
Page speed
How fast the site loads for real visitors: Chrome UX Report 75th-percentile LCP, INP and CLS, with a Lighthouse mobile run standing in where a site has too little traffic for field data.
Operational trust
Status page and incident history, security disclosure, compliance and data-processing documentation.
Measured, but not part of the score
Useful to know, but not a mark for or against the product — so these do not affect the ranking.
Openness
Source availability, self-hosting, data export and open standards. Scored and shown, but not part of the composite — paid SaaS is not worse for being paid SaaS.
Maintenance
Release cadence and repository activity. Scored and shown, but not part of the composite — it is only measurable for open repositories.
