> A reactive, DAG-based workflow orchestration server. Define a workflow once as JSON; run it from REST, a web UI, a CLI or an AI agent.

- [Introduction](https://yukta.infenia.com/index.md): Yukta is a reactive, DAG-based workflow orchestration server. Define a workflow once as JSON and run it from a script, a CI pipeline, a web UI or an AI agent.
- [Quickstart](https://yukta.infenia.com/quickstart.md): Run the Yukta server and execute your first workflow in five minutes.
- [Examples](https://yukta.infenia.com/examples.md): Ten ready-to-run workflows and the idea each one teaches.

- [Sessions and workflows](https://yukta.infenia.com/concepts/sessions-and-workflows.md): How workflows are grouped, stored, versioned and addressed.
- [Nodes, edges and ports](https://yukta.infenia.com/concepts/nodes-edges-ports.md): Node roles, how edges and output ports route messages, and how a node with several parents joins them.
- [Messages](https://yukta.infenia.com/concepts/messages.md): The envelope every node receives and emits: payload, metadata, identity and routing.
- [Executions](https://yukta.infenia.com/concepts/executions.md): The life of one run: its statuses, how they change, what you can read while it runs and what you get at the end.
- [Delivery and back-pressure](https://yukta.infenia.com/concepts/delivery-and-backpressure.md): What Yukta guarantees about delivery, ordering and memory, and how a slow node affects the rest of the graph.
- [Failure handling](https://yukta.infenia.com/concepts/failure-handling.md): Per-node retry, error routing, failure budgets and join rules, set with the engine object in a node's configuration.
- [Time limits](https://yukta.infenia.com/concepts/time-limits.md): The five independent clocks that bound an execution, and how pausing and long-running work interact with them.
- [Sub-workflows](https://yukta.infenia.com/concepts/sub-workflows.md): Run another stored workflow from inside a node, once per message.

- [Variables and expressions](https://yukta.infenia.com/building/variables-and-expressions.md): Reference message data, settings and secrets inside node configuration without storing them in the workflow.
- [Routing and branching](https://yukta.infenia.com/building/routing-and-branching.md): Patterns for sending messages down different paths: by exit code, HTTP status, expression, validation result, recipient list and error.
- [Loops and retries](https://yukta.infenia.com/building/loops-and-retries.md): Repeat work until a condition holds, within bounds, and choose between a loop, an engine retry and a polling loop.
- [Approvals and signals](https://yukta.infenia.com/building/approvals-and-signals.md): Hold a message until a person or another system sends a named signal, with a timeout and an accept or reject decision.
- [Scheduling](https://yukta.infenia.com/building/scheduling.md): Run a workflow on a timer with SCHEDULE_TRIGGER, or start workflows from outside with REST, the CLI or MCP.
- [AI and agents](https://yukta.infenia.com/building/ai-and-agents.md): Build model-driven workflows: chat with memory, tool-using agent loops, decisions, budgets and guardrails.
- [Built-in plugins](https://yukta.infenia.com/plugins/overview.md): The 34 triggers, processors and terminals that ship with Yukta, and how a build chooses which ones to include.
