How does SaaSearch verify MRR and revenue metrics?

SaaSearch connects directly with payment processors (Stripe, Paddle) via read-only authentication and public telemetry. Verified products receive a green checkmark badge confirming their live MRR and monthly visitors.

How do I get my SaaS product discovered and listed for free?

Founders can submit their tool at /submit. Simply enter your website URL for AI metadata autofill, embed the SaaSearch backlink badge on your website, and your product goes live immediately with zero queue delay.

Can I buy or acquire bootstrapped SaaS products on SaaSearch?

Yes. Founders can mark their listings as 'Open for Sale' with transparent asking prices, ARR multiples, and deal terms in our Acquire Hub. Buyers can initiate confidential acquisition discussions directly.

How are daily upvotes and rankings calculated?

Rankings prioritize upvote velocity (momentum gained in the last 24 hours), verified revenue growth, and community engagement. This ensures emerging indie products get equal visibility alongside established brands.

Viaduct: C4 Modeling Tool with an MCP Server for AI Coding Agents

5.0(1)

Viaduct is an innovative C4 modeling tool designed to help software development teams create, maintain, and interact with live architecture diagrams. It allows users to visually define system contexts, containers, components, and code, enriching each element with dynamic documentation, sequence diagrams, and API contracts. The tool uniquely features an MCP (Model-Code Protocol) server, enabling AI coding agents like Cursor or Claude Code to read and understand the architecture, making diagrams actionable. Viaduct ensures that architectural documentation remains current and accessible, solving the common problem of stale diagrams and empowering teams to build and evolve complex systems with clarity.
