Nanocoder
Nanocoder is an open coding agent for your terminal, built by the Nano Collective rather than a company: no paid tiers, no telemetry, and the model is yours to choose. Opper is one of the provider templates in its setup wizard, so you pick Opper, paste your key, and the wizard fetches your available models, giving Nanocoder any of 700+ models on one key with EU-hosted routes available.

Add Opper in Nanocoder
Run /settings providers and pick the Opper template (newer than v1.32.0), or add a provider named Opper with baseUrl https://api.opper.ai/v3/compat and apiKey ${OPPER_API_KEY} to your config.
Run Nanocoder across our providers
On Opper, Nanocoder 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.
