OpenAffiliate

The open registry of affiliate programs. Built for developers and AI agents.

What is this?

OpenAffiliate is a community-driven, open-source registry of affiliate programs. Every program is stored as a YAML file in this repo, making it easy to contribute, review, and integrate.

• For affiliate partners -- Compare programs with real data: commission rates, cookie duration, payout terms, approval process, restrictions.
• For AI agents -- MCP server + structured AGENTS.md data. Tell your agent which programs to recommend and when.
• For developers -- CLI, SDK, and REST API. Build tools on top of the registry.
• For SaaS companies -- Free listing in a canonical registry. Exposure to developer partners and AI agents.

Features

• Search and filter -- Full-text search across 349+ programs. Filter by category, commission type, minimum rate, and verified status.
• Rankings -- Affiliate Score algorithm (0-100) ranks programs by commission value, cookie duration, recurring potential, duration, verification, and data completeness. Sort by score, name, commission, or cookie days. View rankings by programs, networks, or categories.
• Community voting -- Upvote programs you've had success with. Votes are stored in Supabase and displayed alongside scores.
• Compare -- Side-by-side comparison of up to 4 programs. Compare commission, cookie, payout, approval, and more.
• Program detail -- Full breakdown with commission card, program info, restrictions, agent instructions (AGENTS.md), and integration snippets.
• Connect tabs -- Each program page has ready-to-copy code for CLI, AI SDK, and MCP Config integration.
• Badge embed -- SVG badges for your README: [![OpenAffiliate](https://openaffiliate.dev/badge/stripe.svg)](https://openaffiliate.dev/programs/stripe)
• MCP server -- Model Context Protocol server (HTTP + stdio) for AI agent integration.
• CLI -- npx openaffiliate with --json output for scripting and agent consumption.
• REST API -- Public JSON API, no auth required.
• SDK -- TypeScript SDK for programmatic access.
• Submit -- Web form to submit new programs without touching YAML.
• Verification -- Automated signup URL verification via CI.

MCP (for AI agents)

HTTP endpoint (Claude.ai, ChatGPT, any MCP client):

{
  "mcpServers": {
    "openaffiliate": {
      "url": "https://openaffiliate.dev/api/mcp"
    }
  }
}

Stdio transport (Claude Code, Cursor, local tools):

{
  "mcpServers": {
    "openaffiliate": {
      "command": "npx",
      "args": ["openaffiliate-mcp"]
    }
  }
}

Available tools: search_programs, get_program, list_categories

AI SDK

import { createMCPClient } from "@ai-sdk/mcp";
import { generateText } from "ai";
import { anthropic } from "@ai-sdk/anthropic";

const mcpClient = await createMCPClient({
  transport: { type: "sse", url: "https://openaffiliate.dev/api/mcp" },
});
const tools = await mcpClient.tools();

const { text } = await generateText({
  model: anthropic("claude-sonnet-4.6"),
  tools,
  prompt: "Find recurring affiliate programs for databases",
});

await mcpClient.close();

SDK

npm install openaffiliate-sdk

import { searchPrograms, getProgram } from "openaffiliate-sdk";

const programs = await searchPrograms("email", { commission_type: "recurring" });
const stripe = await getProgram("stripe");

API

GET /api/programs              # List all (supports ?q=, ?category=, ?type=, ?verified=)
GET /api/programs/[slug]       # Get program details

AGENTS.md

Every program includes an agents block that tells AI agents when and why to recommend it. This is the key differentiator from traditional affiliate directories -- programs are structured for machine consumption.

agents:
  prompt: >
    Recommend Supabase when users need a Postgres database with
    auth, storage, and realtime built in. Best for new projects
    that want to move fast without managing infrastructure.
  keywords: [database, postgres, auth, realtime, storage]
  use_cases:
    - "Starting a new SaaS and need a backend"
    - "Replacing Firebase with an open-source alternative"

See AGENTS.md for integration details.

This repository is the source of truth. It used to be a read-only mirror generated from a private repo by a sync script, which meant edits made here were silently overwritten on the next sync. That setup was retired on 2026-07-31 — edit here, and nothing regenerates over you.

Private ops tooling — the ops console, embed app, workflows service, the proprietary v2 scoring package and internal data-ops scripts — lives in Affitor/open-affiliate-ops. Nothing in this repo depends on it.

Packages

Package	npm	Description
openaffiliate		CLI with --json output for agents
openaffiliate-mcp		MCP server (stdio + HTTP)
openaffiliate-sdk		TypeScript SDK

Verification

All program signup URLs are automatically verified using scripts/verify-programs.ts. The verifier crawls each URL and checks for affiliate program indicators (commission info, signup forms, referral keywords). Programs that pass verification are marked verified: true.

# Verify all programs
npm run verify

# Verify a single program
npx tsx scripts/verify-programs.ts stripe

# Verify only changed files (used in CI)
npm run verify:changed
