BlueprintBazaar - Factorio Blueprint Monetization Marketplace

Factorio players spend hundreds of hours designing perfect factory blueprints and then give them away for free in Discord servers or random Pastebin links. BlueprintBazaar is a paid blueprint marketplace with preview rendering, tag search, and one-click in-game import. Think Gumroad for Factorio engineers.

What is it?

Factorio has over 4 million copies sold and a notoriously obsessive community that trades blueprints constantly on Reddit and the official forum. There is no dedicated paid marketplace — the official Mod Portal only hosts mods, not blueprints. BlueprintBazaar lets creators upload blueprint strings, auto-renders a factory preview using factorio-blueprint-editor (open source JS library), tags them by purpose, and sells them at $1-$10 each with an 80/20 creator split. Buyers get a one-click copy-to-clipboard import string. Built with Next.js, Stripe Connect for creator payouts, and the factorio-blueprint-editor library for free preview rendering. Why fully buildable now: factorio-blueprint-editor is a maintained open-source JS library that renders blueprint previews in browser with zero game install required.

Why now?

Factorio 2.0 launched in October 2024 with Space Age DLC, causing the largest player count surge in the game's history — blueprint sharing on r/factorio hit all-time highs and creator demand for monetization is fresh and unmet in April 2026.

▸Blueprint string upload with auto-rendered factory preview using factorio-blueprint-editor in-browser.
▸Tag-based search by category: trains, circuits, smelting, megabase, starter.
▸Stripe Connect creator payouts with 80/20 split and monthly payout dashboard.
▸One-click clipboard import string delivery after purchase confirmation.

Target Audience

Factorio players — estimated 500k active monthly players on Steam with a highly technical creator subset of roughly 20k blueprint designers sharing on Reddit weekly.

Example Use Case

A Factorio veteran uploads 12 megabase blueprints priced at $3 each, earns $480 in the first month from 200 sales, and uses the creator dashboard to see which blueprint tags drive the most purchases.

User Stories

▸As a Factorio veteran, I want to sell my megabase blueprints for $5 each and receive automatic Stripe payouts, so that I earn income from 500 hours of engineering work.
▸As a new Factorio player, I want to browse blueprints by category with a live preview before buying, so that I know exactly what I am getting before spending $3.
▸As a blueprint creator, I want a dashboard showing which of my blueprints sell best by tag, so that I can focus on creating more of what buyers actually want.

Acceptance Criteria

Blueprint Preview: done when factorio-blueprint-editor renders a visual preview for any valid blueprint string in under 3 seconds client-side. Purchase Flow: done when Stripe checkout completes and signed R2 URL is delivered to buyer email without errors. Creator Payout: done when Stripe Connect account receives correct 80% split within 7 days of sale. Marketplace Search: done when tag filter returns relevant blueprints in under 1 second.

Is it worth building?

20% take on $5 avg sale x 500 sales/month = $500 MRR at month 3. 20% take x 5,000 sales/month = $5,000 MRR at month 9.

Unit Economics

CAC: $0 via organic r/factorio posts. LTV per creator: $96/year (assuming $10/month avg earnings x 80% share x 12 months, platform keeps 20%). Gross margin: 95% (Stripe fees only).

Business Model

Marketplace commission

Monetization Path

20% platform commission on each sale. Optional $5/month creator pro for analytics and featured listings.

Revenue Timeline

First dollar: week 3 at launch. $500 MRR: month 3. $2k MRR: month 7. $5k MRR: month 12 with Satisfactory expansion.

Estimated Monthly Cost

Vercel: $20, Supabase: $25, Cloudflare R2: $5, Stripe Connect fees: ~$15. Total: ~$65/month at launch.

Profit Potential

Side income viable at $1k-$5k MRR, full-time with Satisfactory expansion.

Scalability

Medium — can expand to Satisfactory and Dyson Sphere Program blueprint formats, doubling TAM.

Success Metrics

Month 1: 50 blueprint listings, 30 sales. Month 3: 300 listings, 500 sales/month. Month 6: first creator earning $200/month.

Launch & Validation Plan

Post in r/factorio asking who would pay $3-$5 for a verified megabase blueprint, measure upvote and comment response, DM top blueprint sharers offering founding creator status.

Customer Acquisition Strategy

First creator: DM 10 top blueprint posters in r/factorio offering founding creator badge, 90% revenue share for life, and featured placement in exchange for listing their top 5 blueprints at launch. Ongoing: r/factorio weekly posts, Factorio Discord server drops, Steam community hub posts.

Suggested Frameworks

Time to Ship

3 weeks

Required Skills

Next.js, Stripe Connect payouts, Supabase, factorio-blueprint-editor JS integration.

Resources

factorio-blueprint-editor GitHub repo, Stripe Connect docs, Supabase storage docs, Factorio wiki blueprint string format.

MVP Scope

pages/marketplace.tsx for browse, pages/blueprint/[id].tsx for listing with preview, pages/creator/dashboard.tsx for sales, lib/blueprintEditor.ts wrapping factorio-blueprint-editor, api/purchase.ts for Stripe checkout, api/payout.ts for Stripe Connect, Supabase schema for blueprints and purchases tables, Cloudflare R2 for blueprint string storage.

Core User Journey

Browse marketplace -> click blueprint -> see live preview -> pay $3-$5 via Stripe -> copy import string -> paste into Factorio in 30 seconds.

Architecture Pattern

Creator uploads blueprint string -> R2 storage -> factorio-blueprint-editor renders preview client-side -> Supabase stores metadata -> buyer pays via Stripe Checkout -> purchase record created -> blueprint string delivered via signed R2 URL.

Data Model

Creator has many Blueprints. Blueprint has many Purchases. Purchase belongs to one Buyer. Creator has one StripeConnectAccount.

Integration Points

Stripe Connect for creator payouts and buyer checkout, Supabase for blueprint metadata and purchase records, Cloudflare R2 for blueprint string storage, factorio-blueprint-editor for in-browser preview rendering.

V1 Scope Boundaries

V1 excludes: blueprint versioning, bundle packs, user reviews, in-game mod integration, Satisfactory support, team creator accounts.

Success Definition

A Factorio creator the founder has never spoken to uploads a blueprint, prices it, makes their first sale, and receives a Stripe payout without any founder involvement.

Challenges

The Factorio community has a strong free-sharing culture — convincing creators to charge and buyers to pay for blueprints requires positioning around time-savings for the buyer, not just revenue for the creator.

Avoid These Pitfalls

Do not launch without at least 30 blueprints listed — an empty marketplace kills conversion instantly. Do not try to sell blueprints the community already shares freely on Reddit; focus on exclusive megabase and circuit designs that take 50-plus hours to engineer. Finding first 10 paying customers requires seeding supply first — buyers will not come without inventory.

Security Requirements

Supabase Auth with Google OAuth or email magic link. RLS on blueprints and purchases. Signed R2 URLs expire in 15 minutes post-purchase. Input validation on blueprint string format before storage. GDPR deletion endpoint required.

Infrastructure Plan

Next.js on Vercel. Supabase for Postgres and auth. Cloudflare R2 for blueprint string storage. Sentry for errors. GitHub Actions for CI. Dev/staging/prod via Vercel preview environments.

Performance Targets

200 DAU at launch, 1,000 req/day. Blueprint preview render under 3s client-side. Marketplace page load under 2s LCP. R2 signed URL generation under 200ms.
