The article explores the concept of local-first software. This approach advocates for software that ensures user ownership and control over their data, emphasizing principles like offline functionality, device independence, secure and private data handling, and long-term data preservation. Through examining various data storage and sharing models and the potential of Conflict-free Replicated Data Types (CRDTs), the authors propose a shift from cloud-centric to local-first applications, aiming to combine the benefits of cloud collaboration with the sovereignty of personal data ownership.

Grafana has deprecated Grafana agent and launch a new Alloy project for replacement

Grafana Agent, our existing OSS telemetry agent, and Grafana Agent Operator are now deprecated and will enter into Long-Term Support (LTS) beginning today (April 9, 2024)


Commercial support will end after the LTS phase, which we anticipate will extend for about 18 months until October 31, 2025. End-of-Life (EOL) phase for Grafana Agent and Grafana Agent Operator will begin once LTS ends. Grafana Agent and the Grafana Agent Operator are expected to reach EOL on November 1, 2025.
