Tandem vs Claude Code

Tandem orchestrates Claude Code. Claude Code is one agent in the terminal.

This isn’t Tandem versus Claude Code. It’s Tandem with Claude Code, or Claude Code alone — and Tandem wins either way.

Claude Code is Anthropic’s terminal coding agent: one Claude agent in your shell that reads, edits, runs, and commits. The single-agent loop is excellent. But it’s one agent, scoped to one directory, talking to Anthropic’s cloud on Anthropic’s models.

Tandem is the layer above it. Your work — code, vault, and history — can stay on hardware you control, with zero telemetry when you run local; your code can stay on your machine, or run in our managed cloud, your call. And there’s one inbox for every model: every agent’s work queued up to diff, comment, approve, and merge.

The three differences that matter

1. Tandem spawns and reviews fleets of Claude Code. A single terminal agent is the unit Tandem orchestrates. One prompt → N Claude Code agents in N isolated git worktrees, across every project at once, all funneled into one review inbox. You ratify; they merge. Claude Code has no worktree-isolated fleet and no merge inbox — it’s one session, one working tree.

2. Local models when you want them — freemaxing. Claude Code sends your code and context to Anthropic’s API; there’s no on-box model path. With Tandem your code can stay on your machine, or run in our managed cloud, your call — and freemaxing lets you point agents at free local models (Ollama, LM Studio), so you may not need a Claude subscription at all. Run Claude Code when you want the frontier model; run free local models when you don’t.

3. One inbox, dashboards, and a knowledge vault. Around the agents, Tandem adds the layer Claude Code doesn’t have: a live fleet dashboard with per-agent cost tracking, approval gates, and an Obsidian-backed knowledge vault. Claude Code gives you per-session /cost and CLAUDE.md files — useful, but not a fleet view or a vault.

Where Claude Code wins (we say so)

Claude Code’s single-agent loop is genuinely best-in-class: deep agentic editing, tight tool use, and direct access to Anthropic’s frontier models with no orchestration overhead. If you want one sharp terminal agent and nothing more, it’s superb — and Tandem is happy to drive it for you. What Tandem adds is everything around that agent: parallelism, multi-project reach, governance, dashboards, a vault, local-first residency, and the freedom to freemax on local models when you’d rather not pay per token.
