Merge

What is Merge?

Merge is an integration platform for software companies. Its Unified product gives developers one API for connecting their app to their customers' third-party systems, with an embedded Merge Link flow for customers to authorize access, sync controls, scopes, webhooks and tools for watching integration health. Merge also offers Agent Handler for connecting AI agents to tools, Gateway for routing requests across large language models with fallback, spend controls and bring-your-own-key, and a Workforce plan with MCP connectors, skills and a desktop client for employees. Teams use it to add many integrations quickly, give customers control over what data syncs, and keep an audit trail. Pricing for Unified starts with a Launch plan: the first 3 production Linked Accounts are free, then $650/month covers up to 10 production Linked Accounts. Professional and Enterprise are contract-based, and Gateway and Workforce have their own pricing pages.

• Add customer integrations through one API
• Let customers authorize data access in your app

Why use Merge

How to get started with Merge

1. Sign up and use the free allowance of production Linked Accounts.
2. Embed Merge Link so your customers can connect their own systems.
3. Read normalized data through the unified API and set sync frequency and scopes.
4. Watch linked-account health and fix issues as Merge flags them.
5. Move to Professional or Enterprise through sales as volume and requirements grow.

Merge limitations

• Launch plan billing is based on the average number of production Linked Accounts in the previous month
• New Linked Accounts beyond the first 3 are frozen until a valid payment method is added
• Professional and Enterprise pricing is contract-based
• Sign-up is on the US multi-tenant server; EU and APAC multi-tenant need a conversation with Merge
