Editorial assessment
Good specialized serviceBuild or Skip is a refreshingly pragmatic utility for software builders. Instead of decorating the interface with useless vanity metrics, the team focused squarely on the single metric that dictates project survival: real cash flow.
The platform is honest about its limitations: payment signals are heuristic telemetry derived from checkouts and traffic patterns, not audited corporate balance sheets. Even with that caveat, screening for active payment flows beats the hell out of building on blind assumptions.
The killer feature here is native MCP server support. Being able to pipe live market datasets directly to an AI assistant inside Cursor or Claude Desktop turns tedious competitor validation into an automated background check while you plan your architecture. For solo builders, the subscription easily pays for itself on the first discarded bad idea.

About the tool
Instead of wasting months coding a product in a vacuum only to realize nobody wants to pay for it, Build or Skip focuses on one fundamental signal: where real money is already changing hands. It is a market intelligence and competitor analytics platform built for indie developers, bootstrappers, and startup teams who want to validate commercial demand before writing code.
The service tracks over 130,000 commercial websites and more than 6,000 AI tools, monitoring checkout implementations, domain metrics, and web traffic. Rather than relying on vanity metrics like social upvotes, Build or Skip organizes product research around a pragmatic three-way decision framework:
- Build: Payment signals are consistent, transaction momentum is climbing month-over-month, and customers keep buying.
- Watch: The product shows an initial spike or solid concept, but lacks the track record to prove long-term retention.
- Skip: Commercial signals are flat, decaying, or isolated flashes in the pan.
The platform provides several research databases:
- Product Revenue Rankings: Explores active commercial sites alongside 6-month momentum, estimated order brackets, and supported payment gateways like Stripe, PayPal, Dodo Payments, and Polar.
- New Site Revenue Rankings: Identifies newly registered domains from RDAP data that are already converting visitors into transactions.
- Tip Revenue Rankings: Analyzes voluntary payments across hundreds of Buy Me a Coffee pages to uncover organic user demand in free tools.
- Backlink Libraries: Curates active comment targets and specialized AI tool directories with verified submission fees and link requirements.
For technical founders, Build or Skip includes a REST API for programmatic domain audits (Ahrefs DR, traffic breakdown, RDAP records, and on-page SEO structure) and a native MCP server bridge to pipe live market intelligence directly into AI workflows.
How it helps you
Build or Skip helps indie developers, solo founders, and product teams eliminate guesswork during project discovery by building strictly where money is already moving:
- Demand Validation: Confirm that buyers are actively paying for similar solutions before spending engineering hours on an MVP.
- Early Competitor Reconnaissance: Detect brand-new domains generating immediate transactions right after registration.
- AI Agent Integration: Query live market datasets and competitor snapshots directly from Cursor or Claude Desktop via MCP.
- Distribution Intelligence: Discover active submission directories and backlink opportunities with pre-checked pricing and reciprocal requirements.

Frequently asked questions
How does Build or Skip calculate payment signals and revenue rankings?
Build or Skip aggregates heuristic signals by detecting checkout providers (such as Stripe, PayPal, Dodo Payments, and Polar), transaction flows, and web traffic. These signals represent conservative transaction ranges and momentum brackets for comparative research, not verified merchant revenue or audited banking records.
How do I connect Build or Skip to AI tools using MCP?
You can connect using the open-source build-or-skip-mcp package for clients supporting stdio MCP servers, such as Claude Desktop or Cursor. Authentication works either through a browser-based OAuth 2.1 login via the command line or by generating a static bos_mcp_ API key stored in your client's environment variables.
What is the difference between the Site Data API key and the MCP API key?
The keys serve different endpoints and are not interchangeable. Keys prefixed with bos_site_ are strictly for the REST Site Data API to query DR, domain registration, traffic, and on-page metrics. The MCP server requires credentials prefixed with bos_mcp_ or an interactive OAuth session.
Can I test Build or Skip for free before purchasing a subscription?
Yes. A free preview mode allows you to browse the top 20 ranked domains in the web dashboard. Full access to the complete database of tens of thousands of ranked domains, the new-site revenue tracker, backlink libraries, and unlimited API or MCP queries requires a Pro plan.
