Open Source TypeScript CI/CD Tools

Vercel combines the best developer experience with an obsessive focus on end-user performance. Our platform enables frontend teams to do their best work. Developers love Next.js, the open source React framework Vercel built together with Google and Facebook. Next.js powers the biggest websites like Twilio, for use cases in e-commerce, travel, news, and marketing. Vercel is the best place to deploy any frontend app. Start by deploying with zero configuration to our global edge network. Scale dynamically to millions of pages without breaking a sweat. Frontend development is not meant to be a solo activity. The Vercel platform makes it a collaborative experience with deploy previews for every code change, by seamlessly integrating with GitHub, GitLab, and Bitbucket. Avoid surprises by iterating with your entire team. Test from the perspective of your users, on every platform.

Unleash is the enterprise FeatureOps platform that gives teams real-time control over how software behaves in production. Decouple deployment from release, roll out gradually, target users, run experiments, and roll back instantly without redeploying. SDKs evaluate flags locally, so no end-user data is sent to Unleash. This project is Unleash Open Source: free, self-hosted (AGPL-3.0, PostgreSQL, Docker), no seat limit, with 1 project, 2 environments and up to 5,000 flags. Unleash Enterprise PAYG costs $75/seat/month with unlimited projects and environments, hosted by us or self-hosted (5-seat minimum), with a 14-day free trial. Custom Enterprise adds an annual contract, a 99.99% uptime commitment, severity-based support and cloud, self-hosted or hybrid deployment. Built on an open-source foundation with 45M+ Docker pulls, and trusted by Lloyds Banking Group, Prudential, Visa, Samsung, Wayfair and Lenovo.
