eventsourcing

A library for event sourcing in Python.

hexcore

Reusable core for Python projects with hexagonal architecture, DDD, CQRS and background tasks. Ships the abstractions and the infrastructure: SQL session layer, FastAPI factories, worker runner, dynamic cron and identity.

noeta-sdk

Python SDK for durable AI agents: survive crashes, pause for human approval at no cost, scale from a script to a multi-host cluster. Any LLM (Anthropic, OpenAI-compatible), MCP, self-hosted.

okf-agentbus

Local MCP event log for multi-agent workspaces

eventsource-py

An event sourcing library for python

cks-runtime

Sessions, transactions, and version history for your knowledge graph. Operate without becoming the authority.

activegraph

Event-sourced graph runtime for durable and stateful agents

polign-recall

Typed, durable agent memory with corrections, history, and replay. Go, Python, and MCP.

python-cqrs

Event-Driven Architecture Framework

ankka

A serverless platform for agentic AI on Apache Pekko. Write entities, workflows, agents and endpoints in Scala, Python, TypeScript or Rust, test them without a runtime, and deploy them to Kubernetes with one CLI.

noeta-runtime

Python SDK for durable AI agents: survive crashes, pause for human approval at no cost, scale from a script to a multi-host cluster. Any LLM (Anthropic, OpenAI-compatible), MCP, self-hosted.

minos-microservice-common

🐍 Minos is a framework which helps you create reactive microservices in Python

eventsourcing-helpers

Python library for practicing the event sourcing pattern using DDD

vibey-engine

Open-source orchestrator for AI coding agents: a spec interview, unattended builds on local (Ollama) or paid agents, human-gated review, and an append-only PostgreSQL ledger so a crashed agent's work is picked up, not lost.

yoetz

Yoetz — local-first structured work evidence, deterministic checks, and honest verification receipts.

infinity-bus

Middleware-native async event bus — extensible, type-safe, one dependency.

depeche-db

A library for building event-based systems on top of PostgreSQL

minos-microservice-networks

🐍 Minos is a framework which helps you create reactive microservices in Python

changex

Provenance-first change tracking for AI document edits — native Word track-changes + a portable, hash-chained .changex journal. Works with any model (MCP + CLI). docx · xlsx · csv · pptx · md.

attestari

Auditable memory for AI agents — provable deletion (crypto-shred + signed certificate), a tamper-evident audit chain, and bi-temporal time-travel recall. Runs on SQLite or Postgres.

causal-continuity-engine

Continuity, causal invalidation, and proof for long-running coding agents

substrate-kernel

A Python runtime that coordinates models and anything else you want through a single append-only log. Replay, diff, and trace every run.
