Where Kilo fits

Kilo is the natural upgrade path when Aider’s CLI workflow is useful but you need a shared team product, or when Claude Code’s agent experience is attractive but Claude-only model access is too limiting.

Frequently Asked Questions

Find quick answers to common questions.

Yes. The audit confirmed Aider’s open-source positioning and GitHub repository references across the crawled docs corpus.

Yes. The audit found Aider documentation for broad model support, including Ollama and local/OpenAI-compatible APIs.

Choose Aider for a lightweight terminal-first open-source assistant. Choose Kilo when you also need IDE integration, cloud agents, Slack, centralized billing, usage analytics, SSO/SCIM, and audit logs.

Yes. Kilo Desktop is in beta for macOS Apple Silicon, Windows, and Linux. It uses the Kilo CLI agent engine and combines agent chat with files, git, terminals, interactive Python notebooks, and conda environments. Its built-in local model server, notebooks, and conda environments require a Kilo account. Desktop is an alternative workspace, not a requirement to replace your existing IDE.

Individual platform access is free. Teams costs $15/user/month; Enterprise is custom. Paid inference and cloud compute are separate. Kilo Gateway charges provider rates with no inference markup; a 5% processing fee applies to card purchases of credits, including optional Kilo Pass. Seat subscriptions and non-card payments are excluded from that processing fee. BYOK covers inference through your provider, not Kilo cloud compute.

The VS Code extension, JetBrains plugin, and CLI are MIT-licensed. Gateway and Cloud backend code are source-available under their repository license, with security and abuse-protection exclusions. These component licenses should not be generalized to the entire hosted platform or Desktop application.

Yes. Kilo supports provider credentials and compatible local inference, including Ollama and LM Studio. Desktop also has a managed local model server for imported GGUF files. Local inference keeps prompts out of hosted model providers, but does not by itself make the whole application offline or air-gapped. Hosted features and connected tools have their own data flows.

Cloud Agents support repository-based work, webhook triggers, and scheduled triggers; triggers are in beta. The current documentation limits each message to 15 minutes, so break long jobs into steps. Cloud compute is billed separately from inference, including with BYOK. Local tools and MCP support should not be assumed to work identically in a hosted environment; check the current Cloud Agent documentation for limits.
