The Frigg Integration Framework

Accelerating Integration
The Open Source Way

Last Updated: November 2021

The Frigg Framework is Left Hook's approach to solving the hard integration challenges faced by SaaS leaders.

Frigg's potential for your SaaS is best explained by pithy paragraphs. For that reason, please read our Frigg Overview: Key Concepts & Considerations white paper (PDF).

But if you're in a hurry or just need to share a short summary, here it is:

What is Frigg?

Frigg is an open software framework built to accelerate development of universal integrations with your tech partners.

Frigg Puts the "Tech" in "Tech Partnerships"

Frigg is software that accelerates development of high-value universal integrations between your product and its partners. From simple one-way automations to richly embedded “UX surfaces,” Frigg powers sticky integrations ready to co-promote.

Frigg-powered integrations are configured from within your own UI or integrations page, and come ready to list in your partner’s directory, including top marketplaces like the Shopify’s App Store, Hubspot’s App Marketplace, Salesforce’s AppExchange, and dozens more.

A Library of Ready-to-Use Connectors

Frigg includes a growing library of API Modules, code blocks that connect to your target partner’s APIs. The existing library includes Crossbeam, Salesforce CRM, Stripe, HubSpot, QBO,, Dropbox, and 25+ more. As Frigg becomes more widely adopted, this library will expand and improve quickly, opening up new and quick partnership opportunities.

Not SaaS, and Definitely Not IPaaS

Frigg is not a hosted service, nor is it an embedded white-label iPaaS like or Workato. The framework is open, customizable, and will be forever “owned” inside your company’s code base. Once launched, pay your chosen cloud provider directly and at “cost.” Your ISV remains in full control of packaging and pricing.

Open, Developable, and Scure

A qualified Javascript developer can improve or build a new Frigg-powered integrations today. While not yet open source, Frigg’s use will be under an open source license sometime in 2021, followed by a modern developer experience and package.

Tech Stack(ed)

Frigg is written in Node.js and relies on the framework, but is otherwise adaptable to your organization’s stack and CI/CD processes.
