From zero to five live SaaS products in one week. Here is what I learned, what broke, and what I would do differently.
The Challenge
I wanted to test: can one developer, armed with Claude and Next.js, ship real products in a week?
The answer: yes, but with caveats.
The 5 Products
-
AccessiScan (fixmyweb.dev) - WCAG accessibility scanner, 201 checks
-
CaptureAPI (captureapi.dev) - Screenshot + PDF generation API
-
CompliPilot (complipilot.dev) - EU AI Act compliance scanner
-
ChurnGuard (paymentrescue.dev) - Failed payment recovery
-
DocuMint (parseflow.dev) - PDF to JSON parsing API
All built with Next.js, TypeScript, Tailwind, deployed on Vercel.
What Worked
-
AI for boilerplate code (auth, API routes, UI components)
-
Vercel for instant deployment
-
Upstash Redis for rate limiting and usage tracking
-
Stripe for payments (surprisingly easy to integrate)
What Did Not Work
-
Trying to make everything perfect before shipping
-
Building features nobody asked for
-
Spending too long on design before validating demand
The Numbers (Honest)
Product Pages Build Time Revenue
AccessiScan 40+ 8h $0
CaptureAPI 40+ 6h $0
CompliPilot 40+ 10h $0
ChurnGuard 45+ 12h $0
DocuMint 40+ 8h $0
Yes, zero revenue so far. Building is the easy part. Finding customers is the hard part.
Lessons Learned
-
Ship fast, iterate based on feedback
-
AI accelerates coding 3-5x but you still need to understand what you are building
-
The European Accessibility Act creates real demand for accessibility tools
-
Payment recovery is a real problem - 30 percent of SaaS revenue is lost to failed payments
-
Distribution matters more than product quality
What I Would Do Differently
-
Start with one product, not five
-
Find 10 potential customers BEFORE building
-
Use cold email outreach from day one
-
Focus on SEO content from the start
All products are live with free tiers. Try them out and let me know what you think!

Anthropic cuts off the ability to use Claude subscriptions with OpenClaw and third-party AI agents
Are you a subscriber to Anthropic's Claude Pro ($20 monthly) or Max ($100-$200 monthly) plans and use its Claude AI models and products to power third-party AI agents like OpenClaw ? If so, you're in for an unpleasant surprise. Anthropic announced a few hours ago that starting tomorrow, Saturday, April 4, 2026, at 12 pm PT/3 pm ET, it will no longer be possible for those Claude subscribers to use their subscriptions to hook Anthropic's Claude models up to third-party agentic tools, citing the strain such usage was placing on Anthropic's compute and engineering resources, and desire to serve a wide number of users reliably. "We’ve been working hard to meet the increase in demand for Claude, and our subscriptions weren't built for the usage patterns of these third-pa

Docker Model Runner vs Ollama: Local AI Deployment Compared 2026
Docker Model Runner vs Ollama: Local AI Deployment Compared 2026 Docker entered the local AI space. If you are already running models with Ollama, you are now looking at a second option that speaks the same language — literally the same OpenAI-compatible API — but comes from the company that standardized how the world ships software. Docker Model Runner (DMR) shipped with Docker Desktop 4.40 in mid-2025 and has been evolving fast. It uses llama.cpp under the hood, stores models as OCI artifacts on Docker Hub, and integrates directly into Docker Compose workflows. Ollama, meanwhile, remains the default choice for local LLM deployment with 52+ million monthly downloads, a broader model library, and an ecosystem that every AI coding tool already supports. The question is not which tool is obj
How to Publish a Paid API for AI Agents Using MCP and AgenticTrade
How to Publish a Paid API for AI Agents Using MCP and AgenticTrade Most API monetization guides assume your consumers are humans who browse a marketplace, read your docs, and manually configure auth. That assumption is becoming outdated. AI agents do not browse. They query a service registry at runtime, read machine-structured MCP tool descriptors, execute calls autonomously, and handle payment without a human in the loop. The infrastructure for that workflow is what AgenticTrade is building. This article walks through the practical steps to register your API on AgenticTrade — an MCP-native marketplace where AI agents can discover, authenticate, and pay for your API per call in USDC. What MCP Actually Does Here MCP (Model Context Protocol) is a protocol for exposing tools and data sources
