Copy this
Standard HTML form
<form method="post"
action="https://forms.example.com/forms/contact/submit?token=TOKEN">
<input name="name" placeholder="Name" required>
<input type="email" name="email" required>
<textarea name="message"></textarea>
<button>Send</button>
</form>Submissions go to your dashboard. Forward to email or webhooks.
One line on your server sets it up with Chasen: HTTPS, live backups of the database, and an update each night. Production-ready in minutes.
Allowed sites, rate limits, a honeypot, and Cloudflare Turnstile. Spam protection that works without you thinking about it.
Forward submissions to your inbox or POST them anywhere. Export to CSV when you need it.
One file holds everything. No Postgres, no Redis, no database server to manage. Chasen copies each change to your own bucket, about a second later.
No usage limits, no surprise bills. You control the infrastructure and the costs.
Not us, not a third party. Data stays on your server. Period.
