Why developers pick open-source coding agents
Model choice is the main reason. An open agent can be pointed at whichever model is strongest or cheapest this month, at a company gateway, or at a local model, without waiting for a vendor to support it. The second reason is trust: an agent that reads your codebase and runs commands is easier to adopt when its behaviour can be audited.
Activity matters more here than for commercial tools, because a project with a single maintainer can stall. Check the latest release date and the release count before building a workflow around one.
