    Per-field fill rules: generated data, fixed value, your own data, or skip
  • Datasets
    Datasets module: build, generate, or import rows of test data

  • 60+ locales

  • Simple Form Backend
    Postform provides a straightforward form backend service that allows developers to add form functionality to static websites without needing to write server-side code or manage a backend infrastructure.
  • Easy Integration
    Integration is typically as simple as pointing your HTML form's action attribute to a Postform endpoint, making it very quick to set up for static sites, landing pages, and JAMstack projects.
  • No Server-Side Code Required
    Postform eliminates the need to set up and maintain server-side code for handling form submissions, which is ideal for developers working with static site generators or simple HTML pages.
  • Email Notifications
    Form submissions can be forwarded directly to your email, providing a convenient way to receive and manage responses without needing to log into a separate dashboard constantly.
  • Spam Protection
    Postform includes spam filtering mechanisms to help reduce unwanted or bot-generated form submissions, saving users time on managing junk entries.

Possible disadvantages

  • Limited Brand Recognition
    Postform is a lesser-known service compared to competitors like Formspree, Getform, or Basin, which means there may be fewer community resources, tutorials, and third-party integrations available.
  • Feature Limitations on Free Tier
    Like many form backend services, Postform may impose restrictions on the number of submissions, forms, or features available on free or lower-tier plans, which could be limiting for growing projects.
  • Vendor Dependency
    Relying on a third-party service for form handling means your forms are dependent on Postform's uptime and continued operation. If the service goes down or shuts down, your forms stop working.
  • Limited Customization
    Compared to building your own backend, using Postform may offer limited options for custom processing logic, advanced validation, or complex workflows triggered by form submissions.
  • Data Privacy Concerns
    Sending form data through a third-party service means your users' data passes through and is stored on external servers, which may raise privacy or compliance concerns depending on your industry or region.

Questions & Answers

As answered by people managing Fillr.app and Postform.

What makes your product unique?

Fillr.app's answer

It leads with control, not random fill. Capture any web form as a reusable preset, set per-field rules (generated, fixed, your own data, or skip), and refill in one click — plus a built-in Datasets module to build, generate, and export test data. A form-filler and test-data manager in one, no code.

Why should a person choose your product over its competitors?

Fillr.app's answer

Fake Filler only sprays random data; Mockaroo generates data but can't fill forms. Fillr does both — and lets you fill with your own data, with reusable presets, per-field control, and 60+ locales. No scripts.

How would you describe the primary audience of your product?

Fillr.app's answer

QA engineers and developers who repeatedly test web forms and need realistic, controllable test data. Demo and sales engineers are a natural secondary audience.

Which are the primary technologies used for building your product?

Fillr.app's answer

Next.js 15, React 19, and TypeScript dashboard; a Manifest V3 Chrome extension built with Vite and supabase for backend
