What Log Bull is

Log Bull is an open-source log collection and search tool for developers and small teams. It receives logs from code and provides a dashboard for searching by text, fields, and time ranges, with live tailing and structured parsing. One installation can serve multiple projects. Log Bull is free to self-host under the Apache 2.0 license, storing logs locally on the server in a mounted data volume. Installation options include an automated script, Docker run, and Docker Compose. Client integrations cover Python, Go, Java, JavaScript, C#, PHP, Ruby, and Rust, with cURL examples; JavaScript also offers a standalone logger and Winston and Pino transports. Project settings can require API keys, filter ingestion by domain or IP, and set ingestion, storage, and retention limits. Roles control system and project access, while setting changes create an audit log. Documented defaults include 1,000 logs per second, 64 KB maximum log size, 100 million stored logs, 100,000 MB storage, and 180 days retention. Minimum requirements are 2 CPU cores, 4 GB RAM, 20 GB disk, Docker Engine 20.10+, and Docker Compose v2.0+.
