How to Choose the Right AI Developer Tool
- Workflow Stage: Coding (Copilot/Cursor), debugging (DeepCode/Sentry), testing (Testim/Mabl), or deployment (Harness/CircleCI).
- Team Size: Solo devs can use free tools like Codeium; enterprises need scalable options like SonarQube.
- Platform: Web (Webflow), mobile (AppGyver), or AI dev (Hugging Face).
- Budget: Start with free tiers or open-source (Aider, CodeQL); scale to paid for teams.
Pro Tip: Combine tools (e.g., Copilot for coding + Sentry for monitoring) for a full-stack AI workflow.
