Compare a Web3Forms alternative you can switch to by changing one URL
FormThunder is a Web3Forms alternative that takes the same HTML fields, so a form moves over by changing its action URL and access key. The two offer the same 250 free submissions a month. FormThunder adds an MCP server and a CLI on every plan, and client accounts with client billing for agencies. Web3Forms lists neither on its pricing page. Checked November 2026.

Which one fits you
Web3Forms may suit you better if
- You're already on Web3Forms and everything works. A switch would gain you nothing if you won't use the AI setup or agency features.
- Its Starter plan offers 5,000 submissions for SGD 68 a year, by application. That's cheap if your volume sits there and you qualify.
- You want a service with a track record. FormThunder is new and has no customers to point to yet.
FormThunder may suit you better if
- You want Claude Code, Cursor or another agent to do the setup, from creating the form to sending a real test.
- You run forms for clients and want to bill them through your own Stripe.
- You want to see each delivery's status and attempts, and retries for up to 24 hours.
Moving from Web3Forms
- Change the form's

Questions
Is FormThunder affiliated with Web3Forms?
No. FormThunder is a separate product that accepts the same form fields.
Will my Web3Forms key work on FormThunder?
No. You need a new key from FormThunder. The field that carries it is still called access_key.
Do prices compare directly?
Not quite. Web3Forms lists prices in Singapore dollars and bills through Paddle. FormThunder lists US dollars and bills through Stripe.
