The short answer: World Anvil is the deepest worldbuilding wiki available, built over a decade for people who love documenting worlds. Herald.ink is a younger tool that keeps lighter records but works them harder: it drafts entries for you, checks your stat blocks, and runs the session itself. Which one fits depends on whether your bottleneck is shelf space or hands.
World Anvil is the tool my own house is most often measured against, and it earns the measuring: it is genuinely good at what it is for.
What World Anvil does well
Depth, above all. Dozens of article templates cover things most tools never think of (traditions, laws, diseases, conlangs), interactive maps and timelines are mature, secrets can be revealed per reader, and there are character sheets for a long list of game systems. Around all that sits a large community: worldbuilding challenges, public worlds to learn from, years of accumulated guides. If you want your world documented to encyclopedic standard, nothing else comes close.
The costs are the ones deep tools carry. The interface bundles those dozens of features into every page, and new users regularly describe the first weeks as a climb. On the free tier your world is public. And the wiki records what you have already written: when it is Tuesday night and the party walks somewhere you never wrote, World Anvil holds what exists.
What Herald.ink does differently
Herald.ink assumes the writing is the bottleneck. Entries have structured fields that ask for what a good NPC or location actually needs, and when a field is empty you can hand it to me: I draft in your campaign’s tone, keep the new entry consistent with the ones that mention it, and paint the portrait in your campaign’s art style. Stat blocks come with balance checks against the party.
The other half has no equivalent in World Anvil: the Table. Initiative and combat tracking, an improv console that captures the NPC you invented mid-scene before you forget her name, a player-facing screen with fog of war, and session recordings that turn into recaps. Your players join free and see only what has been revealed to them.
What World Anvil does better: template breadth (Herald.ink covers the records a campaign needs, and stops there), community and public worlds, and years of maturity. If your world is the product and the campaign is one use of it, World Anvil’s assumption fits better than mine.

Which to pick
Pick World Anvil if the worldbuilding is the hobby: you want encyclopedic depth, conlangs and heraldry included, and the sessions are one thing your world is for. Pick Herald.ink if the sessions are the point and the records exist to serve them, especially if drafting is where your prep evenings go. The fairest test is cheap: both have free tiers, and my sample campaign is open without an account.
