Fillr is a form filler and test data manager for Chrome โ€” for when it matters what goes into every field. Save any form as a preset with a rule per field, fill it from your own CSV or Excel rows, and manage all your test data in one place. Realistic generated data (110+ types, 60+ languages) is built in โ€” but you decide where it goes.

Anyone can spray random values into a page. Fillr is for when the data has to be right.

๏ฟฝ EVERY FIELD, YOUR RULES โœ“ Capture any form once and save it as a reusable preset โœ“ Set a rule per field: Generate, Fixed value, Blank, Skip, or Dataset column โœ“ Presets auto-match pages by URL pattern โ€” the right preset surfaces the moment you land on the page (with a picker when several match) โœ“ Preview the fill before you run it โœ“ Unlimited presets, free

๏ฟฝ FILL FORMS FROM YOUR OWN DATA (Pro) โœ“ Link a dataset to a preset, map columns to fields, and fill row by row โ€” sequential with a "row 3 of 20" readout, or random โœ“ Run 50 test cases through the same checkout without typing a single value โœ“ Your edge cases, your real records, your regression rows โ€” not random noise

๏ฟฝ๏ธ A REAL TEST DATA MANAGER โœ“ Import CSV, Excel or JSON โ€” or generate sheets of realistic dummy data โœ“ Edit rows in a spreadsheet grid, organize with tags โœ“ Export any dataset to CSV, Excel or JSON

โšก INSTANT FILL, WHEN YOU JUST NEED VALUES One click auto-fills every field with realistic fake data โ€” names, emails, addresses, phones, dates and more. Zero setup, works on any site, one-click Clear when you're done.

๏ฟฝ 60+ LANGUAGES (Pro โ€” English is free) Generate locale-accurate names, addresses and phone numbers in French, German, Japanese, Arabic and dozens more for international testing.

๏ฟฝ๏ธ POINT-AND-CLICK, 100% NO-CODE A side panel plus a draggable floating bar on the page. Fill, clear, capture, switch presets โ€” no scripts, no selectors, no JSON to edit.

socketify.py features and specs

  • High Performance
    Socketify.py is designed for high scalability and performance, leveraging an efficient event loop and native extensions to handle a large number of concurrent connections efficiently.
  • WebSocket Support
    The library provides built-in support for WebSockets, making it suitable for real-time applications where persistent connections between client and server are necessary.
  • Asynchronous I/O
    Socketify.py is built on top of asynchronous I/O paradigms, allowing non-blocking operations that can improve the throughput of networked applications.
  • Ease of Use
    The library offers a clean and straightforward API with examples and documentation, which lowers the barrier to entry for developers who are new to network programming in Python.
  • Python Integration
    Being a Python library, socketify.py integrates well with existing Python applications and can be included as part of larger, multi-component systems.

Possible disadvantages of socketify.py

  • Limited Adoption
    As a relatively new or niche library, socketify.py might have a smaller user base and community compared to more established frameworks like Flask or Django, which could result in fewer community resources and third-party integrations.
  • Learning Curve
    For developers who are accustomed to synchronous programming paradigms, adapting to the asynchronous programming model of socketify.py may require an initial learning investment.
  • Documentation Depth
    While there is documentation, it might not be as extensive or comprehensive as those of more mature libraries, potentially requiring more experimentation or source code reading to fully grasp advanced features.
  • Potential Stability Issues
    Being less established, there might be undiscovered bugs or stability issues in production environments compared to long-standing Python networking libraries.
  • Ecosystem Limitations
    The library might lack some of the extensive third-party plugins or tools available in more popular frameworks, which could limit its extensibility.

Questions & Answers

As answered by people managing Fillr.app and socketify.py.

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 โ€” 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 โ€” 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

  • Show HN: Python framework is faster than Golang Fiber
    These "benchmarks" are useless, they're not testing anything real world except the performance of uWebsockets. There are copy errors all over the place.

  • This is how I started the development of the fastest ASGI and WSGI Server in TechEmPower Benchmarks
    After starting the project called socketify.py at https://github.com/cirospaciari/socketify.py, I got pretty good results and reviews, but many people asked if socketify.py could be used to create a WSGI and ASGI server. WSGI and ASGI have a lot of overhead, that's is why I choose not to use them in the first place, but adding an ASGI and WSGI server allows a lot of code already written to run faster!
