Fossil vs Gerrit Code Review

Fossil is a free, distributed software configuration management system for controlling and tracking software-project development and history. It combines version control with bug tracking, a wiki, forums, email alerts, chat, and technical notes. Its built-in web interface includes ticketing, documentation, timelines, full-text search, histories, diffs, ZIP downloads, and access management. Fossil is distributed as a single self-contained executable and can run as a standalone server or through CGI, SCGI, inetd, or stunnel. Official precompiled binaries are available for Linux, Mac, and Windows, and it can be self-hosted. Network communication uses HTTPS or SSH; synchronization supports autosync and manual merges, with autosync enabled by default. Repositories use an SQLite database with atomic transactions and consistency checks before commits. The project supports an automatic GitHub mirror and originated as a tool for the SQLite project. Fossil is offered under a 2-clause BSD license. Listed limitations include no file locking, large-file handling, sparse checkout, or nested repositories.

Gerrit Code Review is a free, self-hosted web system for collaborative review of Git repositories through patchset workflows. Teams can discuss changes with inline comments, manage patchsets, and configure approval processes. Fine-grained access controls determine who can access code. Gerrit lists integrations with Jenkins, GitHub Actions, Zuul, REST API, and webhooks for CI/CD and other automation. The project says global replication and active-active clustering can support thousands of concurrent developers, and presents the system for small teams through large organizations, including regulated industries. Gerrit is Apache 2.0 licensed. Its listed plan costs nothing, with no licensing fees and use at any scale without restrictions. Supported platforms are API, Linux, self-hosted, and web. Documentation and community provide support; the community supports the last three releases on a best-effort basis without a guaranteed response or resolution SLA. Plugin reliability is not guaranteed, and ongoing maintenance is not guaranteed for plugins without direct maintainers.
