Software doesn't maintain itself

Your contributions are keeping this project good. Dear ImGui is used by many projects. The main library is available under a free and permissive license, but continued maintenance and development have been a many-years full-time commitment for me, which we'd like to sustain and grow (including hiring focused contributors more often). In addition to maintenance and stability there are many desirable features yet to be added.

Dear ImGui has first been conceptualized and prototyped in 2012, first released and developed as a side-project from 2014, then became my main focus from the end of 2017. You can read 10 years of Dear ImGui if you are interested in the history of this project. Thanks to sponsors, in 2020, we poured ~2500 hours of work into Dear ImGui R&D. In 2021 ~1600 hours.

Dear ImGui in 2024 is incredibly more powerful and versatile than Dear ImGui was 2014. We are committed to keep improving the software while keeping it sane, optimal, flexible, respectful to the user. Every engineering team will benefit from it.

We are consistently doing R&D and sitting on unfinished features needing work.

We have answered thousands of community questions/issues in the open and in one centralized place in order to create a database of knowledge.

We have created a test engine & test suite to test the library, minimize regressions, facilitate contributions and effectively contributes to documenting the code (pro-tip: if you are unsure what some code is for, disable it and run the test suite!).

We are ensuring at every moment that the library is the most efficient it can be (with strict standards aligning with the needs of game developers, such as: 0 allocation on most frames).

We are designing easy and well-documented transitions to updated APIs when changes are necessary, because code written by users often lives for years or decades.

But we can only keep doing that and move forward with continued support.

How to financially support Dear ImGui? (Businesses)

  • You can support continued development and maintenance via invoiced sponsoring.
  • You can support continued development and maintenance via invoiced technical support, enterprise support, maintenance contracts. Your engineering team will be able to reach us directly, save time, minimize issues and tech debts, get prioritized bug fixes, and benefit from all sorts of technical support.
  • You may purchase commercial licenses for Dear ImGui Test Engine, which is a separate project, useful if you want to automate processing and testing of your tools, engine or game. Its licensing scheme is designed to support funding the main library.
  • *COUGH* it is perfectly ok to buy hours of support and not use them all. It is perfectly ok to buy licenses and not use the Test Engine thoroughly. Whatever makes it easiest for your company to fund Dear ImGui we can work with.
