Codewhale
Codewhale is an open-source coding agent for your terminal: give it a task and it reads the repository, edits files, and runs commands until the task is done or it needs your input, with /receipts listing every file it changed, command it ran, and web or MCP call it made. It works with more than 40 built-in providers and with models on your own machine. Opper ships as one of those providers, so you pick Opper in /provider, paste your key, and Codewhale runs on any of 700+ models with a live model list.

Add Opper in Codewhale
In Codewhale (0.10.3 or later), open /provider (or press F3), choose Opper and paste your key, or set OPPER_API_KEY; on older builds add a [providers.opper] table with base URL https://api.opper.ai/v3/compat.
Run Codewhale across our providers
On Opper, Codewhale can reach every provider in the catalogue. Pick where your inference runs, keep it in the EU when you need to, and use zero data retention on supported routes.
