# App Stack Builder

> A free AI-powered tech stack builder and tool directory for founders and developers. Describe what you are building and get a recommended stack that fits your budget, plus independent comparisons, alternatives, pricing and free-tier details for 100+ developer tools (hosting, databases, auth, payments, AI coding assistants, agent frameworks, vector databases and more).

Every page on this site has a clean Markdown version: append `.md` to any URL, or send an
`Accept: text/markdown` request header. The links below already point at those Markdown files.

## Core pages

- [Build vs buy](https://appstackbuilder.com/index.md): Every tool in the catalog priced both ways — what the SaaS costs, and what it costs to build and run the same thing yourself.
- [Stack generator](https://appstackbuilder.com/build-stack.md): The stack generator itself — describe your app in plain English or answer a few questions and get a budgeted, tool-by-tool stack recommendation.
- [Stack cost audit](https://appstackbuilder.com/my-stack.md): Enter the tools you already pay for and get a build-vs-buy verdict on the whole stack, with the upkeep cost of self-hosting each one.
- [Tool directory](https://appstackbuilder.com/tools.md): Every tool in the catalog with pricing, free tiers and category filters.
- [Categories](https://appstackbuilder.com/categories.md): Category hubs ("best hosting", "best vector database", …) with hand-researched picks and trade-offs.
- [Alternatives](https://appstackbuilder.com/tool-alternatives.md): Per-tool "alternatives to X" pages built from same-category tools.
- [Prebuilt stacks](https://appstackbuilder.com/stacks.md): Ready-made stack templates for common app types (SaaS, AI app, marketplace, mobile).
- [Blog](https://appstackbuilder.com/blog.md): Long-form guides and head-to-head tool comparisons, updated through 2026.
- [Launches](https://appstackbuilder.com/launches.md): Daily feed of newly launched developer tools submitted by their makers.
- [Submit a tool](https://appstackbuilder.com/submit-tool.md): How makers get a tool listed in the directory and the launch feed.
- [Startup listing directories](https://appstackbuilder.com/directories.md): Launch platforms, startup directories, AI tool directories and review sites that accept product submissions — every URL verified reachable, with confirmed submit pages where one exists.
- [MCP server](https://appstackbuilder.com/mcp.md): Public, read-only MCP endpoint at https://appstackbuilder.com/mcp (Streamable HTTP, no API key): search_tools, list_categories and get_alternatives over the tools catalog.
- [Contact](https://appstackbuilder.com/contact.md): How to reach App Stack Builder: support for listings, submissions and corrections; business for partnerships, press and legal.
