Forms and surveys decision
Web3Forms
A competent developer can build and run a dependable, single-tenant replacement in about a week; Web3Forms' main value is convenience and integrations rather than proprietary moat, so self-hosting is realistic for technical users.

Every project below is open source and already does this job today. Fork one, self-host it, or take the parts you need - the build prompt further down assumes an empty file, and this is the shortcut past that. Licences differ; check the one on each card before you ship. All Web3Forms alternatives, with the arithmetic →
What a replacement has to do
- Receive HTML form POSTs, validate/spam-check, send submission to an email recipient, and store recent submissions for export.
What it still won’t have
- Hosted, managed infrastructure with SLA and uptime guarantees
- Built-in account/access_key management, signup and email verification flows
- Out-of-the-box spam protections (reCaptcha, hCaptcha, Cloudflare Turnstile) and honeypot conveniences
- Third-party one-click integrations (Google Sheets, Notion, Slack, etc.)
- File upload handling and hosted file storage add-ons (paid tiers)
What remains hard
- Product polish and ongoing maintenance
First-year cost
No published price
Web3Forms does not publish a price we could read, so there is nothing to compare against. What building costs is below.

What we assumed
The verdict above measures whether you could build it. This one is only about money.
Runnable build prompt
Build a minimal hosted form-backend using Node.js (Express) + PostgreSQL, deployed to AWS Fargate. Scope: a POST /submit endpoint that accepts standard form fields and an access_key, validates required fields and a honeypot, enforces per-access_key monthly submission quotas, looks up recipient email by access_key, forwards submissions via Amazon SES (or SMTP fallback), stores submissions in Postgres, implements a scheduled job to delete records older than the configured retention (30 days default), and provides a protected admin UI to list recent submissions and export CSV. Out of scope: file upload storage, multi-tenant billing, advanced integrations (Notion/Sheets), and built-in CAPTCHA provider keys. Include error handling, input validation, unit tests for the API handlers, basic integration tests for delivery, and a Dockerfile + Terraform (or CloudFormation) to provision RDS, ECS/Fargate service, and SES access; add runtime logging and health check endpoints.

The base comes from the verdict. Everything under it is a check that either happened or did not, and each one is a fact frozen in this record rather than a judgement made at render time - so the same evidence always produces the same number.
