Cynchro Labs released deepCLI, a REPL that turns natural‑language prompts into full codebases via the Deepseek API. Users type a description, the tool plans architecture, writes files, runs tests and learns from each execution to improve subsequent builds. Installation works on Linux, macOS, Windows and via a one‑line script, creating a virtual environment and storing the API key automatically as open source.

The REPL offers autocomplete, history and subcommands such as deep build to generate projects, deep ask for conversational queries, and deep update to modify existing code without restarting. A build runs through planning, generation, writing, evaluation and learning phases, prompting the user to fix failures or applying automatic corrections with the -f flag. Debug mode logs each pipeline step for inspection.

Beyond local use, deep serve launches a web UI reachable from any device; pairing it with Tailscale provides a stable IP and avoids router port forwarding. The tool also supports HTTPS via an auto‑generated certificate, enabling progressive‑web‑app installation on phones. All commands expose credit balance, build history and configuration, making the suite a self‑contained AI‑powered development assistant.
