Overview

KestraKestraSince 2022-06

Kestra is an open-source, event-driven orchestration platform built to automate and coordinate complex data pipelines, microservices, and multi-agent AI systems. With a modern declarative YAML-first architecture, Kestra enables engineering teams to manage scheduled tasks, webhook triggers, distributed compute jobs, and LLM agent pipelines through code or a rich interactive UI. The platform provides over 600+ pre-built plugins spanning major cloud providers (AWS, GCP, Azure), databases (Postgres, Snowflake, BigQuery), and modern AI ecosystems (OpenAI, LangChain, Hugging Face, Vector DBs). Workflows can execute parallel compute tasks, branch conditionally, manage secrets securely, and handle automated retries with exponential backoff. Kestra eliminates the operational overhead of legacy orchestrators by running statelessly on top of modern container runtimes and Kubernetes, providing real-time workflow visualizers, sub-millisecond execution triggers, and enterprise-grade role-based access control.

Kestra’s architecture is built around an event-driven core powered by Apache Kafka or PostgreSQL for distributed queuing and high-throughput execution guarantees. Each workflow is version-controlled in Git as a declarative YAML specification, enabling full CI/CD integration and infrastructure-as-code automation. For AI engineering, Kestra serves as the deterministic execution backbone: triggering RAG indexing pipelines, coordinating distributed fine-tuning runs, provisioning transient GPU containers, and validating agent tool calls against production database replicas. The platform includes embedded Python, Node.js, and Bash script runners with isolated container sandboxes, comprehensive OpenTelemetry distributed tracing, and real-time execution dashboards.

MeetStream AIMeetStream AISince 2026-05

MeetStream AI is a cloud infrastructure platform and unified REST/WebSocket API that enables engineering teams to deploy intelligent meeting bots across Zoom, Google Meet, Microsoft Teams, and Webex. Instead of managing complex headless browser clusters, audio capture pipelines, and conferencing lobby bypasses, developers use MeetStream to send bots into meetings with a single API call.

The platform captures raw multi-track audio, video streams, and real-time transcripts with native per-speaker identification. MeetStream supports bi-directional interaction: bots can speak natively in the conference, display dynamic video or slide cards, and execute tool calls in response to live verbal triggers. With sub-3-second join latency and native WebRTC transport, MeetStream provides the foundational plumbing for next-generation AI sales copilots and meeting intelligence products.
