Editor Review

DevChat takes a differentiated path of open-source + multi-model + custom workflows, standing out among closed-source coding assistants. Custom workflows are the core highlight — create specialized coding workflows with just a few natural language sentences, more flexible than Cursor's Rules. Support for free switching among top models like GPT, Claude, and DeepSeek avoids single-model lock-in. Its knowledge engineering capability for deep API documentation understanding and automatic executable test generation is rare among peers. Being fully open-source also means enterprises can audit code security. Especially suited for flexibility-focused open-source enthusiasts, technical teams needing customized AI workflows, and advanced developers who want to switch between different models.

Frequently Asked Questions

Is DevChat free?▼

DevChat itself is fully open-source and free, but using commercial models like GPT requires your own API keys and usage costs. Using open-source models is completely free.

Which AI models does DevChat support?▼

Supports GPT/o1, Claude/3.7 Sonnet, DeepSeek/R1, Llama, Qwen, and other mainstream models with free switching.

How do custom workflows work in DevChat?▼

Describe your development process and requirements in natural language, and DevChat automatically generates specialized intelligent workflows. Supports both enterprise standards and personal customization.

How does DevChat differ from Cursor?▼

DevChat is an open-source IDE plugin focused on custom workflows and multi-model switching; Cursor is a closed-source IDE focused on deep AI integration and Agent mode. DevChat is more flexible but requires more manual configuration.
