Deep Dive: Switching from Aldena to Aider

Trade-offs, installation & data architecture

Build vs Fork Verdict: KINDA (the core, yes. the polish, no)

Why fork Aider instead of vibe-coding a Aldena clone?

One room's worth of this is a weekend now that the agent loop ships as an SDK: five role-scoped agents in a Docker sandbox, a manager that hands work down, a prompt before anything destructive, a pull request at the end. What does not fall out of that weekend is the rest of it. A server per project that somebody else patches and meters, ten OAuth integrations that stay authorized, memory that survives the run, and a screen where the person paying for the work can watch it and approve it. Build the room. The building around the room is the subscription.
