Free Tools

Free tools for indie developers building and shipping SaaS products with AI coding agents, Fastify, Vue, Postgres, Stripe, Kamal, and Hetzner.

I use these as small planning and setup helpers around Stacknaut: generate repo-specific agent instructions, compare hosting costs before the bill grows, and check launch work before a product goes live.

AI & Development

Configuration helpers for getting more consistent work out of coding agents. These tools focus on the files and prompts that make an agent understand a repo before it starts changing code.

AGENTS.md Generator

Generate a ready-to-use AGENTS.md configuration file for your AI coding agent. Works with Claude Code, Cursor, Copilot, and more.

Cost & Infrastructure

Planning tools for the parts of SaaS work that become expensive or easy to miss: hosting, deployment, monitoring, launch checks, and the operational details around a production app.

SaaS Hosting Cost Calculator

Compare monthly hosting costs across Hetzner, Vercel, Render, and AWS. See how much you'd save on your own server.

SaaS Launch Checklist Planner

Check infrastructure, auth, billing, SEO, email, monitoring, and smoke tests before launching a SaaS product.
