About these 1.19 seeds

A swamp biome sample within 160 blocks of estimated spawn is required for every seed in this category. Lists are computed separately for the version printed on each card.

1.19 (The Wild Update) added the deep dark, ancient cities and mangrove swamps to world generation, and 1.19.2 remains a huge modded version. These seeds were verified on 1.19 – 1.19.2 generation itself. Note for 1.19.3 and 1.19.4 players: biome and structure layout is identical there, but 1.19.3 changed stronghold placement, so any stronghold distance on a card can differ on those two patches.

Verified for Java Edition 1.19 – 1.19.2 (The Wild Update) — the line most 1.19 modpacks pin. Biomes and structures match on 1.19.3 – 1.19.4 too, but stronghold positions shift there.

For the current Java 26.3 release, see the main swamp seeds — or the same list for 26.3 · 1.21.4 · 1.20 · 1.18 · 1.16. All 1.19 lists live under best 1.19 seeds.

Frequently asked questions

How is this different from the main swamp seeds page?
These seeds are computed for Java 1.19. The main swamp seeds list targets Java 26.3. Match the version on the card; older versions can generate different biomes and structure positions.
Which releases do these seeds work on?
Verified on 1.19 – 1.19.2 (including 1.19.2 modpacks). On 1.19.3 – 1.19.4 the biomes and structures generate identically, but stronghold positions shift within their rings — so treat stronghold distances as 1.19 – 1.19.2 numbers.
Do these seeds work on Bedrock Edition?
No — Java and Bedrock generate different worlds from the same seed. These lists are Java Edition only.
