Tools we use daily: setups, tricks and battle-tested automations.
Three production coding agents, five real tasks measured by time, tokens, and PR quality. No marketing — the actual measurement.
Claude Code leads long-horizon agentic work, Cursor wins for fast daily interactive editing, Aider dominates CI-pipeline automation, and GitHub Copilot fits teams built around GitHub PRs; Windsurf competes with fresh traction. After a year using all five hard, the most productive combination for most people is still Claude Code plus Cursor.
After fourteen months testing AI-integrated DevOps tools across several teams, the stack that stays is small: Claude Code, Cursor, and Aider for code; PagerDuty AIOps, Datadog Bits AI, and Grafana Assistant for alert triage; and OpenTofu with OPA for infrastructure generation bounded by policy rules.
