Selling Tools to AI Coders: Claude Code, Cursor and Codex Businesses (83 Verified)
Millions of people now code with AI agents. A new kind of small business sells them add-ons.
Our directory has 83 businesses built for developers and AI coding tools (Claude Code, Cursor, Codex, MCP and “vibe coding”) with revenue verified on TrustMRR. The median makes about $297 a month, close to the directory-wide $300 (study). 19 make $1,000 or more.
1. MCP servers that plug into Claude and ChatGPT
MCP (Model Context Protocol) lets an AI assistant use outside tools. Some people sell access to these. The biggest is the Ad and Marketing Tools MCP for Claude and ChatGPT at ~$28,540 MRR. We cover it and the other MCP businesses in the MCP server business guide, so this guide focuses on tools for the coding itself.
2. Infrastructure for AI-built apps
- Multi-Model AI Media Generation API: $35,542 MRR (Stripe-verified).
- Live Updates for Capacitor Apps (AI-Agent Friendly): ~$32,964 MRR.
- Video Runtime for AI Coding Agents: ~$16,644 MRR.
- Convert AI-Built Sites to WordPress: ~$3,359 MRR.
3. Skills, generators and cost savers
- AI React Native / Expo App Generator: ~$5,370 MRR.
- Paid Library of Agent Skills for Claude Code & Cursor: ~$3,918 MRR, $12,037 in the last 30 days.
- AI Coding Agent Cost Saver (Claude Code/Codex): ~$2,025 MRR.
- Social Scheduler for Developers (API, CLI, MCP): ~$2,168 MRR.
4. Workspaces, phones and dashboards for agent users
People who run coding agents all day pay for small comforts around them.
- Desktop Canvas to Run Claude Code, Codex & Gemini: ~$354 MRR. A calmer desktop for running several agents side by side.
- AI Kanban Coding Tool for Claude Code: ~$295 MRR. Turns a task board into work for the agent.
- Mac Menu Bar App for Claude Code & Codex Usage: ~$234 MRR, with $1,442 in the last 30 days. Shows how much of your usage limit is left.
- Claude Code History and Diff Viewer for VS Code: ~$146 MRR. Search past agent chats and the files they changed.
- Claude Code from Your Phone App: ~$134 MRR. Check on an agent away from your desk.
Pattern: each one does one small job well and costs little to build. None is large, but together they show steady demand.
5. Better input for “vibe coders”
Many people building apps with AI are not trained programmers. They pay for help telling the agent what to build.
- Build Web & Mobile Apps from a URL: ~$580 MRR. Start from an existing site instead of a blank prompt.
- Turn App Ideas into AI-Ready Build Prompts: ~$345 MRR.
- Beautiful UI Designs for Vibe Coders: ~$298 MRR. Better-looking designs without burning credits.
- Context Engine for AI Coding Agents: ~$189 MRR.
- Flutter Rules and Skills for AI Coding Agents: $117 in the last 30 days, mostly one-off sales. Rules for one framework.
- Security Scanner for Apps Built With AI Coding Tools: $49 in the last 30 days. Small so far, but a real problem: AI-built apps often ship with exposed keys.
What the data says
- Add AI access to an existing tool. An MCP for ads, analytics or search console earns because the data is already valuable.
- Fix what AI-built apps break. Deploys, updates and migrations are pain points with budgets.
- Small tools add up. Most of the workspace and phone apps earn $100 to $400 a month. They are cheap to build, so a few together can make a real income.
- One-time spikes are common. Several show much more revenue in the last 30 days than MRR, a sign of launches and lifetime deals.
How to start selling to AI coders
- Solve a pain you hit while coding with an agent. Lost context, broken deploys and surprise bills are common complaints. You are your own first customer.
- Fit into their tools. Ship as an MCP server, a Claude Code skill, a CLI or a Cursor rule pack, so users don’t have to leave their editor.
- Show results in minutes. Developers try things quickly and drop them just as fast. A one-line install and a free tier help.
- Plan for the big tools copying you. Claude Code, Cursor and Codex add features every month. Paid tools that last tend to handle hosting, data or a niche the big tools ignore.
Honest catches
- The platforms move fast. Claude, Cursor and OpenAI keep adding built-in features that can replace an add-on.
- Developers expect free. Many will build their own MCP rather than pay. Sell to marketers and agencies using these tools, not only to developers.
