Temporal

The Temporal TypeScript SDK is an open-source framework for authoring workflows and activities in TypeScript or JavaScript against Temporal's distributed orchestration engine. Temporal executes asynchronous, long-running business logic with durable state and recovery across failures, while the SDK provides client packages for starting and interacting with workflows and worker packages for running workflows, activities, and Nexus Operations. Worker-level execution uses Node-specific capabilities including native modules, worker threads, virtual-machine isolation for the workflow sandbox, AsyncLocalStorage, and async hooks. The repository distributes the SDK as version-aligned @temporalio/* packages and officially supports Node.js 20, 22, and 24; alternative server-side JavaScript runtimes may work for some client features but are not officially supported for workers.

Temporal Ruby SDK is Temporal Technologies' official open-source Ruby framework for authoring and running durable workflows and activities. Workflows and activities are defined as Ruby classes; clients start workflow executions, and workers execute them while communicating with a self-hosted Temporal Server or Temporal Cloud. The SDK uses a Rust core and provides workflow testing with automatic and manual time skipping, along with activity invocation, child workflows, timers, cancellation, replay, telemetry, and workflow-safety checks. It is distributed as the `temporalio` Ruby gem and supports macOS and Linux on ARM and x64.

An open-source distributed tracing backend developed by Grafana Labs. Tempo ingests traces via Jaeger, Zipkin and OpenTelemetry (OTLP), stores trace data in scalable object stores (Amazon S3, Google Cloud Storage, Azure Blob Storage, MinIO) using a chunk-based, low-index architecture, and exposes query APIs compatible with Jaeger/OTLP with tight integration into Grafana for visualization. It is available under the Apache 2.0 license and can be run self-hosted (Docker, Kubernetes/Helm) or used as a managed service on Grafana Cloud.

Workday, Inc. is a US-based enterprise software company that provides cloud-native human capital management (HCM), financial management, payroll, talent management, planning, and analytics applications delivered as multi-tenant SaaS.

Founded in 2005 by Aneel Bhusri and Dave Duffield, Workday is commercially licensed enterprise software that includes machine-learning features and an assistant/chat capability but is primarily an enterprise SaaS platform.

Cloudflare Computer is an open-source library that provides AI agents with a virtual filesystem backed by a Cloudflare Durable Object. The Durable Object stores the authoritative state in SQLite, while the workspace exposes a single execution interface through `workspace.runtime.exec(source, { backend })`. It supports three execution backends: Container projects the SQLite state into a sandbox container through a FUSE mount and synchronizes changes over capnweb RPC; Isolate shell runs `just-bash` in a Dynamic Worker; and Isolate JavaScript runs an ECMAScript module in a fresh Dynamic Worker with structured inputs and results, durable relative imports, configured libraries, workspace-backed `node:fs/promises`, and trusted `ws:git` and `ws:artifacts` modules. Workspaces can register multiple backends under stable identifiers, connect to them lazily, or be used solely as a filesystem without an execution backend. The repository includes examples for container, Worker shell, Worker JavaScript, egress policies, MCP, agent workspaces, tutorials, artifacts, and assets. The package is marked preview-only: its APIs are unstable and the repository says it is intended for experiments, exploration, and prototypes rather than production use.
