Sequin provides a real-time, bidirectional sync platform that lets developers interact with APIs using standard SQL commands (SELECT, INSERT, UPDATE, DELETE) directly against their databases. By translating SQL queries into API calls, it eliminates the need to handle pagination, rate limits, or custom API client code, enabling faster data integration and easier feature deployment for engineering teams.

Problem
Developers often spend significant time handling SaaS API integration complexities such as pagination, rate limits, authentication, and custom SDKs, which slows feature delivery and increases maintenance overhead.
Solution
Sequin provides a real‑time, bidirectional sync layer that exposes SaaS API data as relational tables within a developer’s existing database. By allowing standard SQL commands—SELECT, INSERT, UPDATE, DELETE—to read and write API resources, it eliminates the need to work directly with HTTP endpoints or vendor‑specific client libraries. The platform automatically maps schemas, performs backfills, and keeps data synchronized with low latency, while presenting errors in familiar PostgreSQL format. Developers can leverage familiar database tools, indexes, views, and triggers to build integrations quickly and reliably, reducing integration code and operational friction.
Target Audience
Primary customers are software engineers and data teams building or maintaining integrations with SaaS services, especially those needing low‑latency, SQL‑centric access to external API data.
Features
- Real-time, bidirectional synchronization between supported SaaS APIs (e.g., Salesforce, Airtable, HubSpot) and a PostgreSQL‑compatible database
- Full SQL CRUD support on API resources, enabling queries, joins, and aggregations with standard database syntax
- Automatic schema mapping, backfills, and incremental updates that respect source rate limits
- Error handling returned in native Postgres error format for seamless in‑application handling
- Ability to create database objects such as views, generated columns, and triggers that operate on synced API data
- Usage‑based pricing model that charges per monthly active row synced, with decreasing cost at higher volumes
