Best Doom source ports for 2026

Which Doom source port to install — ranked by use-case.

There is no single “best” Doom source port — it depends on what you want to do. Modern modding, online multiplayer and faithful 1993-accurate gameplay are three different requirements with three different answers. Here’s the lineup.

Ranking

#1

GZDoom — best for modding and single-player

9.2/10

If you only install one source port, install GZDoom. The single-player and modding ecosystem revolves around it.

  • + The de-facto target for modern mods (ZScript).
  • + Vulkan + OpenGL renderers, runs on anything.
  • + Active development, frequent releases.
  • − Netcode is weak for online — use Zandronum if multiplayer matters.
#2

Zandronum — best for online multiplayer

8.6/10

Use Zandronum when you want to play Doom with other people online. For everything else, use GZDoom.

  • + Forked from old GZDoom specifically to fix multiplayer netcode.
  • + Active server scene (Doomseeker browser).
  • + Supports a large subset of GZDoom mods.
  • − Lags behind GZDoom on ZScript features — newest mods may not work.
#3

Chocolate Doom — best for vanilla accuracy

8.0/10

For preservation, speedrunning original Doom, or playing demos from 1994 — Chocolate Doom is the right tool.

  • + Bit-for-bit accurate to the 1993/94 executables — same bugs, same physics.
  • + Lowest possible system requirements.
  • − No mod support beyond what original Doom supported.
  • − No high resolutions out of the box (Crispy Doom is the modernised fork).
#4

Crispy Doom — best vanilla+ middle ground

8.3/10

If you want Doom to feel like 1993 but look like 2026, this is the sweet spot.

  • + Chocolate Doom plus higher resolution, uncapped framerate, jumping (optional).
  • + Keeps the vanilla feel without the 320×200 ceiling.
  • − No serious modding support.
  • − No online multiplayer.

Verdict

Default recommendation: GZDoom for one-port simplicity. Add Zandronum if you'll play online. Add Chocolate or Crispy Doom if you care about vanilla accuracy or want to play 1990s demos.

Frequently asked questions

Can I use multiple source ports at once?

Yes — they’re separate programs that don’t conflict. Many Doom players have GZDoom and Zandronum side by side.

Which source port for Doom 3?

None of these. Doom 3 runs on id Tech 4 and uses dhewm3 or RBDOOM-3-BFG as its modern source port — that’s a separate ecosystem.
