The DM's toolkit for D&D 5e: run your table, build worlds, generate NPCs and keep every campaign linked and searchable — plus the full SRD reference. Prep it, run it, remember it.
Hi Product Hunt 👋
We're a small group of people who play D&D — home games, not a studio. RPG Builder started from something almost embarrassingly simple: whenever we were mid-search for a rule or a stat block, what we actually wanted next was to generate something with it, right there. Nobody wants to leave the table to go read a wiki.
So we built that. It's the full SRD reference — 334 monster stat blocks, 319 spells — sitting next to generators that turn what you just looked up into a table-ready NPC, tavern, or encounter, saved straight into your campaign so it's still there three sessions later.
Three things we decided early and haven't broken:
no invented rules (if it's not SRD, we don't make it up), no hostage-taking (your characters, worlds and images export to PDF and Foundry JSON), and a free tier that is actually a tier, not a trial.
We still use it at our own table every Friday. If a feature wouldn't survive a night with four players waiting, it doesn't ship.
Would love to hear from DMs here: what's the thing you always end up improvising because looking it up would kill the pacing?
