temporal

temporalio/temporal · ★ 23.8K

Temporal is a durable execution platform: a server that runs units of application logic called Workflows resiliently, automatically handling intermittent failures and retrying failed operations.

MathModelAgent

jihe520/MathModelAgent · ★ 6.2K

An open-source AI agent for mathematical modeling competitions: it analyzes the problem, builds the model, writes and debugs the code, and produces a formatted paper ready for submission.

etcd

etcd-io/etcd · ★ 52.4K

A distributed, reliable key-value store for the most critical data of a distributed system, written in Go and kept consistent across machines with the Raft consensus algorithm.

conductor

conductor-oss/conductor · ★ 32.3K

An open-source durable execution engine for microservices and AI agents: it persists every workflow step so long-running processes survive crashes, retries, and restarts. It originated at Netflix and is maintained by Orkes and the community.

rqlite
17.8Krqlite/rqlite · Go
rqlite is a lightweight, fault-tolerant distributed relational database built on SQLite — think etcd, but with relational modeling — built to keep your data highly available with minimal effort.
10
Polly
14.2KApp-vNext/Polly · C#
A .NET resilience and transient-fault-handling library that lets developers express strategies like Retry, Circuit Breaker, Hedging, Timeout, Rate Limiter and Fallback in a fluent, thread-safe way.

hive
11.1Kaden-hive/hive · Python
OpenHive is an open-source multi-agent harness for production AI — a runtime that adds state management, failure recovery, observability, cost control, and human oversight so colonies of agents reliably run real business processes instead of demos.
14
orleans
10.9Kdotnet/orleans · C#
Orleans is a cross-platform .NET framework for building robust, scalable distributed applications — from a single on-premises server up to globally distributed, highly available cloud services. It's often referred to as 'Distributed .NET'.
