Important Changes
Notice: Cribl as Code TypeScript and Go SDK Discontinuation
Cribl is stopping active development of the Cribl as Code Go and TypeScript SDKs, which were previously in preview. To give existing users a clear path forward, we are moving the SDKs from the criblio GitHub organization to the Cribl Community GitHub organization and open sourcing them as community resources. This allows customers and community members to continue using the SDKs and build on them, while Cribl steps back from active feature development and long-term support.
The SDKs will continue to be available through their new home in the Cribl Community GitHub organization, where users can keep using them, fork them, and extend them based on their own needs. Customers looking to stay on a supported integration should consider migrating to either the Python SDK, Terraform Provider, or direct Cribl API access. Cribl support will be limited to critical issues only, such as security vulnerabilities or P0 blockers, for the defined transition period. On October 1, 2026, the SDK repositories will be archived and marked read-only.
