What is Sequin?

Editorial review
Sequin provides a real-time, bidirectional sync between various APIs (like Salesforce, Airtable, Hubspot) and your PostgreSQL database. It allows developers to interact with these APIs using standard SQL queries (SELECT, INSERT, UPDATE, DELETE), effectively turning complex API interactions into simple database operations. This eliminates the need to deal with API documentation, query parameters, rate limits, and pagination, significantly simplifying integration development. The product is designed for engineering teams looking to accelerate their development cycles and reduce the complexity of building and maintaining API integrations. By abstracting API complexities behind a familiar SQL interface, Sequin enables faster problem-solving, quicker deployment of new features, and reduces time spent debugging API-specific issues. It's particularly beneficial for those who are already proficient in SQL and database management, allowing them to leverage existing skills for API integration.

Is Sequin worth the price?

90/100

Sequin's pricing model is very generous, especially for early-stage companies, with a free tier up to 10K MAR.

The tiered pricing scales effectively, becoming significantly more affordable at higher usage, dropping from $8.00/1K MAR to $0.08/1K MAR. This structure is best for businesses with fluctuating or rapidly growing API integration needs.

Hidden Costs & Gotchas

No clear overage pricing beyond tiers

Potential for rapid cost increase between tiers

No stated discounts for annual billing

How Sequin Compares to Competitors

Compared to traditional iPaaS solutions like Zapier or Make (Integromat), Sequin's model is highly specialized and potentially more cost-effective for high-volume, programmatic API interactions, as it charges per MAR rather than per task or operation. While Zapier's free tier is limited by tasks, Sequin offers 10K MAR free, which can be substantial for data-intensive use cases.
