Overview
Router.so is a self-hostable headless form backend and lead router for custom web applications. It accepts incoming submissions from plain HTML forms or API calls, validates each payload against a schema, and passes the parsed data to downstream webhooks and email recipients.
Why Router.so instead of Typeform
Hosted form builders like Typeform focus on no-code conversational questionnaires embedded through third-party scripts. For marketing campaigns or HR surveys, that visual builder works well, but embedding an external widget into a bespoke client site or Next.js app introduces layout friction, third-party tracking, and rigid presentation limits. Router.so handles the opposite side of the pipeline: developers build the form controls directly into their own markup or React components, while Router.so serves as the ingestion endpoint that validates fields, prevents malformed posts, and dispatches data to where marketing operations need it.
From an operational workflow standpoint, this separation gives small teams and agencies full control over user experience and data routing without building custom form microservices from scratch. A team can point multiple production sites or WordPress landing pages at dedicated endpoints, verify incoming email addresses and phone numbers against typed schemas, and forward qualified entries directly to HubSpot or webhook workers. You trade Typeform's visual quiz logic and drag-and-drop question builder for clean frontend integration, lower per-seat overhead, and direct database ownership.
What it does well
- Schema validation with Zod enforces typed fields—such as emails, telephone numbers, dates, and constrained string options—before any payload reaches downstream systems.
- Flexible ingestion modes support direct HTML form actions with success and failure redirects, standard JSON fetch requests, or embedded React components.
- Native webhook dispatch and Resend email alerts notify internal staff immediately when an endpoint captures a prospect.
- A central management dashboard displays submission histories, inspection logs, and field validation errors to help ops leads debug broken intake pipelines.
- An official WordPress plugin integration links agency client sites to centralized endpoints through native blocks and shortcodes.
- Pre-built form generation outputs copy-pasteable shadcn/ui React components aligned with modern Tailwind frontends.
