Why this site exists
When Palworld 1.0 launched on July 10, 2026, the breeding combination table wasn’t just “revised” — every one of the 227 returning Pals had its breeding rank changed, and the Paldeck was renumbered. Overnight, every pre-1.0 calculator and community spreadsheet started giving silently wrong answers. We hit that wall ourselves on day one, dug into the updated game data, and built the calculator we wished existed.
Where the data comes from
The dataset is built from datamined 1.0 game files via two independent community sources (the palcalc project and pyPalworldAPI), cross-validated against each other — 299 Pals’ values agree across both with zero conflicts. Our breeding formula implementation is regression-tested against all 44,851 combinations in the official 1.0 table with zero mismatches, which is how we caught details like the tie-break rule (equidistant ranks resolve to the higher rank). Mutation mechanics combine datamined rates with a community report log collected from player testing — every entry is attributed and dated on the mutation page.
Nothing here is copied from other guide sites. Where our data is still awaiting verification, the site says so — every Pal and combination carries a status badge (✓ 1.0 verified, pre-1.0 · pending, or unconfirmed) rather than presenting guesses as facts.
Who runs it
PalHatch is built and maintained by an independent solo developer (with heavy use of AI tooling for the engineering — the data verification methodology above is what we stake the site’s reputation on). It is not affiliated with Pocketpair. The site is free, with no login and no paywall; it’s supported by donations and may show ads in the future.
Update policy
The dataset is re-checked after every Palworld patch — upstream datamine sources and official patch notes are monitored daily, and the “last updated” stamp on every page (July 13, 2026) changes only when the data actually changes. Found something wrong? Tell us — confirmed errors are fixed same-day.
