Basin vs Formidable

Basin handles web form submissions without requiring server code. It can collect entries, filter spam, send email, store files and trigger webhooks. Forms can be built with HTML, a JavaScript library, an API or a no-code builder. Spam controls include CAPTCHA options, AI filtering, honeypots and domain restrictions. File uploads can reach 50GB and include virus scanning. Listed integrations include Slack, Discord, Google Sheets, Zapier, Make, Pipedream, Integrately and webhooks. Security measures include Cloudflare WAF and DDoS protection, signed attachment URLs, token rotation and HMAC-SHA256 webhook signatures. Privacy tools include data receipt emails, deletion and configurable retention. The free plan is free and includes one form, 50 submissions per month, 30-day data retention, 100MB file uploads and one-day event log retention. Paid plans start at $12.50/mo billed annually, and a 14-day trial is available. Submissions exceeding a plan's monthly cap are still delivered and billed at the applicable tier rate.

Formidable is a cloud form builder that generates forms from natural-language descriptions. Conditional logic can show, hide, or require fields based on answers and expressions. Computed fields evaluate in real time for weighted scores, boolean outcomes, and formatted outputs. Business rules can produce approve, reject, or escalation outcomes. Users can publish hosted forms, share links, embed forms in an iframe, and receive submissions through webhooks. A JSON REST API and the open-source Forma React library support custom interfaces. Account, form, and submission data are stored in the European Union. Generation prompts may be processed by Anthropic, while submission and respondent data are not sent to AI services. The Free plan costs nothing and includes one published form, 1,000 submissions per month, conditional logic, computed fields, webhooks, analytics, and a one-time AI-token allowance. Starter costs $15 a month; Pro costs $49 a month. Submissions beyond a plan limit are not accepted until the next billing cycle unless upgraded.
