Free software. Bring your own keys.
Niki is open source under MIT. There is no paid tier, payment processing, account, or billing system. You pay your model provider, or use a local Ollama model.
$0, the whole pipeline.
The open-source release includes the pipeline stages, sandbox backends, plan mode, evals, the TUI, and ACP. There is no feature-gated tier, no seat license, and no hosted requirement.
- Planner, Coder, Tester and Reviewer stages; optional Red / Security / Parallel stages
- Podman or Docker container execution, plus a git-worktree backend
- 12 named providers, custom base_url endpoints, and per-agent model mixing
- Plan mode, sessions, memory, goals, research commands
- Evals harness, audit bundles, optional OTLP trace export
- MIT: use it commercially, modify it, ship it
Provider costs, not Niki seats.
Niki records provider-reported token counts and estimates USD from a dated price table. A positive spend_cap_usd is enforced; 0.0 means unlimited. Unknown or unpriced models report $0.00 for the estimate and emit a warning that the estimate may understate real spend.
| Setup | Reported value |
|---|---|
| Local Ollama | No provider charge |
| Hosted provider | Estimated from price table |
| Unpriced model | $0.00 + warning |
Token counts come from provider reports; dollar amounts are estimates and vary by model, date, and provider. Unknown or unpriced models report $0.00 and warn.
No paid plans or billing.
