100% free + open · terminal native
Cercano is a premium agent harness for working with frontier and open-weight models—separately or together.
brew install cercano-ai/cercano/cercanoInstall nowFrontier + open
A polished terminal, built-in workflows, and deliberate routing put every kind of model inside one coherent way of working.
What Cercano does
Context and compute are choices, not defaults.
Cercano routes work by capability, quality, and destination. Keep demanding reasoning with a frontier model, move bounded work to an efficient model, or run it locally.
Read the feature guideSubagents work in parallel without crowding the main conversation.
Dispatch research, implementation, and verification into separate, scoped contexts. Open any subagent in its own tab, follow its progress, and bring back only what matters.
Read the feature guideGood agent work is a sequence of deliberate moves.
Research, planning, subagent execution, systematic debugging, and design decisions are built into the harness. The process stays visible and repeatable instead of living in one oversized instruction.
Read the feature guideLong sessions keep moving while context is managed in the background.
Layered summaries and non-blocking compaction preserve decisions, current state, and useful history. You can leave, return, and understand where the work stands.
Read the feature guideUsage should be legible enough to change a decision.
See token use by provider, model, source, and time. Cercano makes the tradeoffs between local, efficient, and frontier inference concrete.
Read the feature guideOpen-weight models belong inside the workflow, not beside it.
Cercano manages a local runtime and makes local inference a first-class destination for delegated work, private tasks, and zero-cost iteration.
Read the feature guideUse subscription sign-in, API credentials, or compatible endpoints.
Provider choice remains separate from the coding workflow around it. Switch the underlying model or endpoint without rebuilding how you work.
Read the feature guideThe interface is dense where it helps and quiet everywhere else.
Responsive layouts, rich formatting, visible tool activity, context meters, subagent tabs, and carefully tuned themes make long sessions comfortable.
Read the feature guideHistory is useful when it is searchable and ready to continue.
Automatic titles, saved sessions, search, and resume keep ongoing work close. Pick up the thread without reconstructing the task from memory.
Read the feature guideThe interface and the durable agent core are separate.
An independent service owns sessions, tools, and model access. The terminal stays fast and focused, while headless clients and future interfaces can use the same agent.
Read the feature guideCercano is 100% free and open source under Apache 2.0.
Run it, study it, extend it, and make it your own. The complete agent, terminal, workflows, and local-runtime integration live in the public repository.
