- # Similar projects
-
- There are many projects similar to `EnTT`, both open source and not.<br/>
- Some even borrowed some ideas from this library and expressed them in different
- languages.<br/>
- Others developed different architectures from scratch and therefore offer
- alternative solutions with their pros and cons.
-
- Below an incomplete list of those that I've come across so far.<br/>
- If some terms or designs aren't clear, I recommend referring to the
- [_ECS Back and Forth_](https://skypjack.github.io/tags/#ecs) series for all the
- details.
-
- I hope this list can grow much more in the future:
-
- * C:
- * [destral_ecs](https://github.com/roig/destral_ecs): a single-file ECS based
- on sparse sets.
- * [Diana](https://github.com/discoloda/Diana): an ECS that uses sparse sets to
- keep track of entities in systems.
- * [Flecs](https://github.com/SanderMertens/flecs): a multithreaded archetype
- ECS based on semi-contiguous arrays rather than chunks.
- * [lent](https://github.com/nem0/lent): the Donald Trump of the ECS libraries.
-
- * C++:
- * [decs](https://github.com/vblanco20-1/decs): a chunk based archetype ECS.
- * [ecst](https://github.com/SuperV1234/ecst): a multithreaded compile-time
- ECS that uses sparse sets to keep track of entities in systems.
- * [EntityX](https://github.com/alecthomas/entityx): a bitset based ECS that
- uses a single large matrix of components indexed with entities.
- * [Gaia-ECS](https://github.com/richardbiely/gaia-ecs): a chunk based
- archetype ECS.
- * [Polypropylene](https://github.com/pmbittner/Polypropylene): a hybrid

- * C#
- * [Entitas](https://github.com/sschmid/Entitas-CSharp): the ECS framework for
- C# and Unity, where _reactive systems_ were invented.
- * [LeoECS](https://github.com/Leopotam/ecs): simple lightweight C# Entity
- Component System framework.
- * [Svelto.ECS](https://github.com/sebas77/Svelto.ECS): a very interesting
- platform agnostic and table based ECS framework.
-
- * Go:
- * [gecs](https://github.com/tutumagi/gecs): a sparse sets based ECS inspired
- by `EnTT`.
-
- * Javascript:
- * [\@javelin/ecs](https://github.com/3mcd/javelin/tree/master/packages/ecs):
- an archetype ECS in TypeScript.
- * [ecsy](https://github.com/MozillaReality/ecsy): I haven't had the time to
- investigate the underlying design of `ecsy` but it looks cool anyway.
-
- * Perl:
- * [Game::Entities](https://gitlab.com/jjatria/perl-game-entities): a simple
- entity registry for ECS designs inspired by `EnTT`.
-
- * Raku:
- * [Game::Entities](https://gitlab.com/jjatria/raku-game-entities): a simple
- entity registry for ECS designs inspired by `EnTT`.
-
- * Rust:
- * [Legion](https://github.com/TomGillen/legion): a chunk based archetype ECS.
- * [Shipyard](https://github.com/leudz/shipyard): it borrows some ideas from
- `EnTT` and offers a sparse sets based ECS with grouping functionalities.
- * [Sparsey](https://github.com/LechintanTudor/sparsey): sparse set based ECS
- written in Rust.
- * [Specs](https://github.com/amethyst/specs): a parallel ECS based mainly on
- hierarchical bitsets that allows different types of storage as needed.
-
- * Zig
- * [zig-ecs](https://github.com/prime31/zig-ecs): a _zig-ification_ of `EnTT`.
