Kestra is an open-source, event-driven orchestration platform for data, AI, and infrastructure workflows, built by Kestra Technologies (founded 2021 in Paris, now headquartered in New York). Workflows are defined declaratively in YAML and run on schedules, webhooks, polling, or real-time events such as message-queue messages and object-storage changes, with backfills available from the UI after outages.
The engine is Java-based and self-hosts on Docker, Kubernetes (official Helm charts), or plain VMs, including air-gapped environments. The core repository is licensed Apache 2.0 with no enterprise carve-out; the Enterprise Edition (RBAC, SSO/SCIM, audit logs, worker groups, tenant isolation) is separate closed-source software distributed from a private registry under a license key, and a managed Kestra Cloud is in early access as of July 2026. The platform ships 1,800+ plugins (vendor count, July 2026) and dedicated script tasks for Python, R, Node.js, Shell, PowerShell, C#, Julia, Ruby, Go, and other languages, with SQL handled through database plugins and bidirectional Git sync for version control.
As of July 2026 the project has 27,500+ GitHub stars, a stable 1.3.x release line alongside a maintained 1.0.x LTS, and Kestra 2.0 in release-candidate stage. Kestra Technologies raised a $25 million Series A led by RTP Global in March 2026 (total funding $36 million) and reports 30,000+ organizations and 2 billion workflow executions in 2025, with named customers including Apple, JPMorgan Chase, Toyota, Deutsche Telekom, and Bloomberg. Kestra competes most directly with Apache Airflow, Prefect, and Windmill in the orchestration space.

Workflow AutomationSee How It Ranks
Best Durable Workflow Engines for Production in 2026
A ranked list of the best durable workflow engines for production deployments in 2026. Durable workflow engines persist execution state to a database so that long-running workflows survive process restarts, deployments, and infrastructure failures. The ranking covers Temporal, Prefect, Apache Airflow, Camunda, Windmill, and n8n. Tools were evaluated on production reliability, developer experience, scalability, open-source health, and documentation quality. The shortlist intentionally mixes code-first engines (Temporal, Prefect, Airflow) with hybrid visual platforms (Camunda, Windmill, n8n) to reflect how production teams actually choose workflow engines in 2026.
Best No-Code Automation Platforms in 2026
A ranked list of no-code automation platforms in 2026. The ranking covers visual workflow builders that allow non-engineering teams to connect SaaS apps, route data, and add conditional logic without writing code. Entries cover proprietary cloud platforms (Zapier, Make, Pipedream, IFTTT) and open-source visual builders (n8n, Activepieces). Scoring reflects integration breadth, pricing accessibility, visual editor ease, reliability and error handling, and self-hosting availability.
