Review DevinStart with the reason you are switching. If OpenAI Codex feels too expensive, compare free tiers and usage limits. If it feels too closed, prioritize open source tools. If the workflow does not fit, switch categories entirely: an app builder may solve a founder problem better than an editor, while a CLI agent may solve repository maintenance better than autocomplete.
The best replacement is rarely the tool with the longest feature list. It is the one that improves your current bottleneck while keeping code review, tests, deployment, and ownership clear.
