Summit

Summit is a platform that powers engaging apps for sales, marketing, and product teams to deploy and use anywhere. They offer a low-code editor, API, and Slack channel support for $1, per month. They also offer full-service onboarding and implementation to brainstorm, build, and integrate with your marketing site, sales process, or product.
Summit has everything you need to build, launch, and host your app. The foundation of the Summit platform is a visual code editor, enabling the creation of calculators, forecasts, and simulations that match your vision.
