What is Tyk Open Source
Open source is at the heart of what we do. Anything that is API Gateway-related lives in the Gateway, or is critical for the Gateway to work is open and freely available via our Github. The Tyk Gateway is fully open-source. It’s all the same Gateway that’s used by you (the community!), by our enterprise products, as well as our SaaS. Our commitment to open source also delivers a host of benefits for our users: sign up for free with Tyk, receive securely packaged open source packages, get started guides, access to our community and all of the latest open source information.Tyk OSS, Tyk Open Source, Tyk Gateway, Tyk CE

Free vs paid, in short. Free and open source (MPL 2.0): Tyk Gateway and Tyk Pump; no license needed. The open-source Gateway already includes OIDC (via JWT validation), JWT, Basic Auth and client-certificate (mTLS) authentication, plus rate limiting and quotas. Paid (license key): Tyk Dashboard, Tyk Developer Portal, Tyk Operator and MDCB.
Tyk Operator is designed for Tyk Dashboard and needs a license; it is included in Tyk's paid plans. Kubernetes Gateway API support is coming in Tyk Operator 1.6; today Operator uses Tyk's own custom resources. If a Tyk license lapses, nothing stops working and your existing APIs keep serving traffic; you just can't create or update APIs until it is renewed. There is no grace period, but Tyk reminds you in advance.
Plans: Core, Professional and Enterprise. Pricing is quote-based with no public list prices: Core is priced by the number of APIs managed; Professional by the number of environments and data centres: each environment you run counts, and so does each data centre it runs in (pricing, contact Tyk).
Support is included: both paid plans, Core and Professional, include Tyk's Enhanced success plan, and customers rate Tyk 4.8 out of 5 for Service & Support on Gartner Peer Insights, and 4.7 out of 5 overall from 92 ratings.
