Kestra

What it is for

Kestra is an open-source orchestration desk: you author a Flow (YAML or no-code), and Open Source is $0 (unlimited flows and executions; 2,300+ plugins). Use it when the job is flows you start at $0, not when you need a $20 chat seat.

What makes it unique: the cover is the official Kestra no-code trigger form (io.kestra.plugin.core.trigger.Webhook, id webhook, key) from the docs twozero still — not a pricing card. The form itself is ops of Triggers.

Key features

• Flows — a declarative workflow you version as YAML or edit as no-code (Flows UI; pricing Unlimited Flows & Executions). One graph. The no-code canvas and the YAML panel are the same Flow, not two desks. AI Copilot that writes a Flow is a generate option.
• Executions — a single run of a Flow with logs, outputs, and a Gantt (Executions docs; pricing Unlimited Executions). A run, not a Flow. Retry / kill / replay sit on this card.
• Triggers — a webhook, cron, or event that starts a Flow (Webhook still; pricing Scheduling and event triggers). A start, not a task. Cover Form/Source tabs are ops of this.
• Namespaces — a boundary for flows, files, secrets, and variables (Namespaces). A folder, not a Flow. Multi-tenant isolation is Enterprise hosting, not a fifth namespace type.
• Self-host / Cloud / Enterprise — the Apache-2.0 app you run, Kestra Cloud (request access, pay-as-you-use), or Enterprise Edition (GitHub; pricing Open Source price 0 USD / Cloud / Enterprise). A control plane, not a Flow. SSO, RBAC, worker groups, and Apps print on Enterprise — they are not extra Flow types.

Playground task trials are ops of Flows. Plugins are install. Dashboards chart Executions — ops of Executions.

Who it's for

Best fit: data / platform teams who will stay on Open Source at $0 (unlimited flows and executions, Postgres/MySQL queue) while they ship a first Webhook Flow, then talk to sales for Enterprise when they need SSO, RBAC, and a support SLA — Cloud is request-access with no public dollar on the page.

Pricing

Verified 2026-10-23 (Asia/Shanghai) from kestra.io/pricing. Schema.org on that page prints Open Source price 0 USD. Cloud and Enterprise have no public dollar.

• Open Source — $0. Unlimited flows and executions. 2,300+ plugins. Code and no-code editors. Event-driven scheduling. MCP server. Queue on PostgreSQL or MySQL. Confirmed by the Offer named “Kestra Open Source” (price 0, priceCurrency USD).
• Kestra Cloud — fully managed. “Start small, scale instantly, pay only for what you use.” Request Access. Schema.org describes it as InvoicePrice / “Pay only for what you use.” Do not invent a Cloud dollar.
• Enterprise Edition — annual subscription, per instance, unlimited flows/tasks/executions. SSO / LDAP / SCIM, RBAC, audit logs, worker groups, Enterprise plugins, Apps. Contact sales. Do not invent an Enterprise dollar.
• Support add-on (Enterprise) — Standard (email, P0 24h), Premium (email + dedicated chat, P0 6h), Platinum (24×7, P0 1h). No public dollar on those rows.

Limitations / costs

• Cloud and Enterprise have no public $. Do not copy a reseller figure onto this page.
• SSO, RBAC, worker groups, and Apps are Enterprise. Open Source will not grow those buttons.
• You still run Postgres/MySQL (or Kafka on Enterprise) for the queue. $0 is the license, not the database.
• An orchestration desk, not a notebook. For Python-first flows see Prefect. For asset-first DAGs see Dagster.

Alternatives

• Prefect — Python-native orchestration when your flows already live in Python, not YAML.
• Dagster — asset-oriented DAGs when you want software-defined assets instead of Kestra Flows.
• Temporal — durable function execution when the unit is code + workers, not a YAML Flow.
