Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Pricing registry for developer tools, exposed as an MCP server

Readme


tags:

  • pricing
  • cost-awareness
  • tool evaluation
  • free tier
  • vendor lock-in people:
  • rogermbyrne tools:
  • Vercel
  • Railway
  • Supabase
  • Neon
  • Clerk
  • Resend
  • Stripe
  • Fly.io
  • Netlify
  • Render projects:
  • Pricing.md

Pricing.md

Make your AI agent cost-aware when planning developer tool stacks.

Pricing.md surfaces pricing breakpoints, compares alternatives, flags lock-in risks, and shows where free tiers end — so developers make informed decisions about the tools they choose.

Browse the registry at latest.sh — 303 tools, side-by-side comparisons, transparency scores, and an AI-powered Stack Advisor.

Install as a Skill

The quickest way to use Pricing.md is as an agent skill. No MCP setup needed — the pricing data is embedded directly in the skill.

npx skills add rogermbyrne/pricing.md

Once installed, your agent will proactively surface pricing when you're evaluating tools, planning a stack, or comparing options.

Install as an MCP Server

For programmatic pricing queries (search, compare, estimate cost), you can also run Pricing.md as an MCP server.

Add to your Claude Code MCP config:

{
  "mcpServers": {
    "pricing.md": {
      "command": "npx",
      "args": ["-y", "pricing.md"]
    }
  }
}

MCP Tools

| Tool | Description | | --- | --- | | search_tools | Search and filter tools by category, price range, tags | | get_pricing | Get full pricing details for a specific tool | | compare_tools | Side-by-side comparison of 2-5 tools | | estimate_cost | Estimate monthly cost given usage quantities | | find_cheapest | Find the cheapest tool in a category for your usage | | growth_cost | Compare what tools cost at realistic growth (e.g. 100K MAU for auth, 50GB for databases) — exposes free-tier-to-paid cliffs |

Web UI — latest.sh

The full registry is browsable at latest.sh with:

  • Tool pages with pricing tiers, portability info, and transparency scores
  • Category comparisons with sorting by price, free tier, growth cost, and transparency
  • Side-by-side compare for up to 5 tools
  • Stack Advisor — describe your app, get a recommended stack with real pricing at 3 user scales
  • Pricing changelog tracking when tools change their prices
  • Transparency leaderboard scoring tools on pricing openness (A-F)
  • pricing.md files — every tool has a machine-readable markdown file at /tool/{id}/pricing.md
  • Embeddable SVG badges — transparency score badges at /tool/{id}/badge.svg

How It Works

When you're planning a project and mention tools like Vercel or Resend, the agent will:

  1. Show the free tier and its limits
  2. Show the cost at scale — what does this tool actually cost at 100K users? ($0 → $1,025/mo for Clerk, $0 → $0 for WorkOS)
  3. Flag the free-tier cliff — some tools lure you with free tiers then charge aggressively when you outgrow them
  4. Note portability — open standard (SMTP, PostgreSQL) or proprietary lock-in?
  5. Present, don't recommend — you know your requirements, the agent shows the numbers

Maintaining Pricing Data

Pricing data lives in data/tools/ as JSON files validated against a Zod schema.

# Validate all data files
npm run validate

# Check if any pricing pages have changed
npm run check-freshness

# Re-discover which tools have pricing.md files
npm run discover

Contributing

Pricing.md is community-maintained. Anyone can add a new tool or update stale pricing by submitting a PR.

Quick version: Add a JSON file to data/tools/, run npm run validate, open a PR with a link to the pricing page you used.

See CONTRIBUTING.md for the full guide — schema reference, category list, portability ratings, and review process.
