RPG Builder Reviews and Details

RPG Builder is a Dungeon Master's toolkit for D&D 5e. It brings campaign prep, live sessions, worldbuilding, NPCs, monsters, spells and art into one place, so you stop jumping between a rules site, a notes app, a map tool and an image generator.

My Table runs your campaigns from one command post — sessions, prep and recaps in the order you actually play them. Record a session and it turns into a recap; the NPCs and places from that recap stay linked into My World, where every character, location and plot thread remains searchable between sessions.

Generators produce NPCs, monsters, taverns, loot, settlements and more in one click, saved straight into your world rather than disappearing when you close the tab. The World Builder generates continents, regions and settlements that fit together, and a custom species creator sits alongside the standard SRD options.

It ships the full SRD 5.1 reference: 334 monster stat blocks with an encounter difficulty calculator on the same page, 319 spells with a spellbook builder, plus SRD equipment and magic items. The reference is free to browse without an account.

Three rules we hold to:

• No invented rules. If it isn't in the SRD, we don't make it up. The SRD data is ingested, not generated.
• No hostage-taking. Your characters, worlds and images export out — PDF, Foundry JSON and print are on every generation, including free ones.
• The free tier is a tier, not a demo.

Pricing: Free (10 credits, core character and art generators, first session recap free), Pro $12/month (unlimited campaigns and NPCs, 500 credits/month, no watermark), Ultra $39/month (2000 credits/month, up to 4096px, visual sheet exports).

Note on AI: the generators and the art use AI. The SRD reference does not — it is ingested from the SRD 5.1 (Creative Commons Attribution 4.0), not generated.
