Free for hobbyists. TankBud keeps a whole fishroom in one place. Log water tests and see trends per parameter, set repeating maintenance reminders, and track livestock, plants and equipment per tank with photos. A public care catalog covers 2,000+ fish, invertebrates and corals plus 300+ plants, with tank size, temperature, pH and temperament for each. The free stocking calculator checks a planned community before anything goes in the bag, and saved plans convert into live tanks. Runs in the browser and installs to a phone home screen like a native app.

assertpy features and specs

  • Fluent API
    Assertpy offers a fluent API that makes assertions more readable and expressive, enabling developers to write assertions in a natural language style that is easy to understand.
  • Chainable Assertions
    It allows for chainable assertions, enabling multiple checks to be performed in a single line of code, thereby reducing verbosity and enhancing clarity.
  • Comprehensive Assertion Methods
    The library provides a wide range of built-in assertion methods, catering to various types of data validations, such as checking for size, type, value, and more.
  • Extensibility
    Assertpy supports extending its functionality by defining custom assertions, allowing developers to tailor it to their specific needs.
  • Pythonic
    Designed with Pythonic principles in mind, Assertpy fits seamlessly into Python projects, enabling idiomatic and consistent code style.

Possible disadvantages of assertpy

  • Learning Curve
    Developers new to the library may encounter a learning curve due to the distinct approach of using fluent and chainable assertions as opposed to traditional methods.
  • Limited by Python Version
    The library may have limitations in terms of compatibility with older versions of Python, requiring users to ensure their environment is up-to-date.
  • Performance Overhead
    The additional abstraction layer introduced by a fluent interface might introduce some performance overhead, especially in performance-critical or resource-constrained environments.
  • Less Community Support
    Compared to more established testing libraries, Assertpy might have less community support and fewer resources available for resolving issues or getting help.
  • Dependency Management
    Using a third-party library introduces additional dependencies to manage, which could complicate project maintenance and compatibility.

Questions & Answers

As answered by people managing TankBud and assertpy.

Which are the primary technologies used for building your product?

TankBud's answer

Next.js and React with TypeScript, Postgres on Supabase, deployed on Railway. TankBud is an installable web app (PWA), so it runs in any modern browser and installs to a phone home screen without an app store.

How would you describe the primary audience of your product?

TankBud's answer

Freshwater and saltwater hobbyists, from one betta tank to a whole fishroom. People who want water tests, maintenance and stocking plans in one place instead of a spreadsheet. There's also a business tier for aquarium service companies, fish stores, breeders, and any other business that manages multiple tanks.

Why should a person choose your product over its competitors?

TankBud's answer

Most aquarium apps do logging or calculators, not both. TankBud ties them together, so the same care data behind the public catalog powers the stocking check in your plans and tanks. There's no cost for hobbyists. Paid plans exist for businesses that manage multiple tanks (fish stores, breeders, service companies with client tanks), and those come with a free trial.

What makes your product unique?

TankBud's answer

TankBud connects tracking to care data. The catalog covers a growing list of 1,500+ fish, invertebrates and corals plus 300+ plants, with tank size, water parameters, temperament and tank mates for each. The stocking calculator checks a planned community against that data before you buy anything. Saved plans convert into live tanks with the same logs, reminders and photos.

What's the story behind your product?

TankBud's answer

I'm a long time aquarium hobbyist and a software engineer. I first built TankBud for my own tanks because my water tests, maintenance notes and stocking research were spread across a spreadsheet, a notes app and a pile of browser tabs. I worked on it for a couple of years and it's now officially released. The care catalog and stocking calculator are free for anyone to use, no account needed.
