How the tools compare.
Hero Forge and Eldritch Foundry both win on component quality and physical printing. RPG Builder wins only when the character already exists as art.
Hero Forge — the deepest part library and a real print-and-ship service. Build a miniature piece by piece inside their editor; order it printed and shipped, reported at $29.99 to $44.99 depending on size, or export a digital STL, reported at $3.99 to $10 per file, or subscribe (Pro from around $3.99/mo; Pro+ reported to add roughly 5 digital credits monthly).
Does well: widely reported as the broadest, most curated part library in this category. Complete print-and-ship pipeline — no printer required on your end. Multiple price points from single STL to subscription.
Falls short: building a character means assembling from parts, not from existing art — a mismatch if the character was already designed as a portrait. Reported entry pricing per object adds up across a full party. Best for assembling a character from scratch inside a purpose-built editor.
Eldritch Foundry — the closest direct competitor, with a heavier part library leaning into armour and weapon detail. Confirmed pricing: Eldritch Unlimited subscription from $10/month for unlimited STL downloads; individual STL files around $5; resin-printed minis around $25 at 34mm heroic scale; print-on-demand roughly $35 MSRP per mini.
Does well: confirmed unlimited-STL subscription at a fixed monthly cost, useful for outfitting a whole party. Reported strength specifically in armour and weapon fidelity. Both digital and physical output like Hero Forge.
Falls short: denser interface than Hero Forge, which reportedly slows the first session. Same part-bin starting point — no way to build from an existing portrait. Best for armour and weapon fidelity — paladins, warlords, anyone in full plate.
RPG Builder — starts from a portrait instead of a part bin. Feed it a character image and it generates the 3D model from that art, rather than requiring the character to be rebuilt piece by piece.
Does well: no redesigning a character that already exists as 2D art — the model stays in sync with the portrait. Stays attached to that character's Codex record, not a separate asset. In-browser 3D preview before spending any credits.
Falls short: less manual control over individual armor pieces than either Hero Forge or Eldritch Foundry. No print-and-ship pipeline — export is STL or GLB only, printing is on you. Best for a miniature that matches a portrait you already have, from any source.

| Digital STL (reported) | $3.99–$10 per file, or subscription | ~$5 per file, or $10/mo unlimited | Included in generation credits |
| Subscription (reported) | Pro from ~$3.99/mo | Eldritch Unlimited from $10/mo | Pro — 500 credits/period, all tools |
| Part-library depth | Deep, broad | Deep, armour/weapon-focused | Not applicable |

Match the job, then the tool.
Keep Hero Forge for a physical miniature shipped to your table with the broadest general-purpose part library, or for assembling a character from scratch inside a purpose-built editor.
Reach for Eldritch Foundry specifically for armour and weapon fidelity — paladins, warlords, anyone in full plate — where its heavier part library shows.
Switch to RPG Builder for a miniature that matches a portrait you already have, from any source. Building a new part-library character means designing it twice; generating from the existing portrait keeps the two in sync and stays attached to that character's Codex record.
Plan costs side by side.
Hero Forge and Eldritch Foundry are both priced per-object at a similar range: digital STLs roughly $4 to $10, physical minis roughly $25 to $45, with optional subscriptions in the $4 to $10/month range for either unlimited or metered digital downloads.
Ours is credit-metered across every tool, not just miniatures: 10 credits at signup, Pro at 500 per period covers miniature generation alongside images, video and everything else. Dollar amounts are on the pricing page, not here.
These are not close substitutes on cost. Hero Forge and Eldritch Foundry are priced for buying individual, often physical, objects. We are priced for volume of digital generation across many tools — and we do not compete in the physical-object category at all.
How to switch in ten minutes.
There is no import between a part-library build and a generated model — different pipelines from the ground up. Start from the portrait you already have.
Minutes 0 to 3: pick a character with existing portrait art from the Codex, gallery, or any generator here.
Minutes 3 to 6: generate the 3D model from that portrait, choosing a quality tier for the detail you need.
Minutes 6 to 9: inspect it in the 3D viewer before exporting — check proportions and pose match the source art closely enough for your table's standards.
Minutes 9 to 10: export STL for your own printer, or GLB for a VTT token rather than a physical object. If the goal is specifically a shipped physical miniature and you do not own a printer, that step stays with Hero Forge or Eldritch Foundry — neither of us offers it.
Common DM questions about this lineup.
What comes up most when comparing part-library minis against portrait-generated ones.
Can Hero Forge, Eldritch Foundry and RPG Builder produce the same mini?
Not identically — the first two assemble from curated part libraries with fine manual control; we generate from a 2D portrait with less part-level control but no rebuilding work if the character already has art.
Does RPG Builder offer physical printed miniatures?
No — export is STL or GLB for your own printer or a print service. Both Hero Forge and Eldritch Foundry offer shipped physical minis with no equivalent here.
Which is cheaper, Hero Forge or Eldritch Foundry?
Reported pricing is similar in range for both — compare based on part-library style (Eldritch Foundry leans armour-heavy) rather than price alone.
Do I need good source art for the generated model to work well?
Yes — model quality depends on the input portrait, and full-body art produces better results than a close-up face shot.
