ai-memory
AkitaOnRails
Open-source, self-hosted long-term memory server that lets Claude Code, Codex, Cursor and other agent CLIs share context and hand off sessions.
Key features
- Cross-Agent Handoffs: Typed, claim-once handoffs let you continue a session in a different agent CLI.
- Automatic Capture: Lifecycle hooks record prompts, tool calls and session boundaries, sanitized before storage.
- Markdown Wiki Storage: Git-backed wiki of .md files is the source of truth, with a rebuildable derived database index.
- Multi-Mode Search: Full-text, entity and graph search plus optional vector search.
- Team Sharing: Per-project knowledge sharing with multi-user auth, per-person attribution and an audit log.
- Self-Hosted Single Binary: Rust binary or Docker server running on your laptop, homelab or LAN host.
- Zero-LLM Default: Capture and search work without an LLM API key.
- Broad Agent Support: Works with Claude Code, Codex, Cursor, Gemini CLI, OpenCode, Kiro CLI, Grok Build CLI and more.
Best for
- A developer starts a feature in Claude Code and continues it in Codex without re-explaining the project.
- A team shares project knowledge across members' coding agents with an audit trail.
- An engineer keeps memory on a homelab server so every laptop and agent sees the same context.
- A privacy-focused user runs fully local memory capture with no LLM calls or cloud service.
- A maintainer browses and edits agent memories as plain markdown in a git repository.
- A developer onboards a new agent CLI to an existing project through MCP install commands.
Dagster
Dagster Labs
Cloud-native data orchestration platform to build, schedule, and monitor reliable data pipelines for teams.
Key features
- Python-First Declarative Model: Define data assets, jobs, and pipelines as Python functions and objects, making pipeline logic testable, reusable, and versionable.
- Integrated Lineage and Observability: Capture lineage and runtime metadata automatically to enable tracing of data asset provenance and diagnose failures across pipelines.
- Local-to-Production Workflow: Support for local development, unit and integration tests, staging environments, and production deployments on Docker/Kubernetes and managed cloud.
- Extensive Integrations Library: Prebuilt integrations with popular data tools (databases, data warehouses, DAG runners, orchestration components, and ETL tools) to simplify connectivity and execution.
- Scheduler and Execution Engines: Built-in scheduling and pluggable execution engines to run pipelines on varied compute backends and scale workloads.
- Best-in-Class Testability: Facilities to write unit and integration tests for assets and jobs, enabling safer deployments and CI workflows.
- Cloud and Self-Hosted Options: Open-source engine for self-hosting and a commercial Dagster Cloud for managed orchestration, enterprise controls, and support.
- Declare data assets and pipelines as Python functions using a declarative programming model
- Integrated lineage tracking and observability for assets and runs
- Built-in scheduling and orchestration for pipeline execution
- Designed for end-to-end development lifecycle: local dev, unit/integration tests, staging, production
- Library of integrations for popular data tools and ecosystems
- Supports deployment to Docker, Kubernetes, and Dagster Cloud
- Open-source Apache 2.0 licensed with community and enterprise ecosystem
- Focus on testability and best-in-class developer experience
Best for
- Building asset-centric ETL/ELT pipelines where data artifacts are declared as Python functions and automatically kept up-to-date by declarative scheduling.
- Running local development and CI workflows that exercise the same pipeline code used in production, enabling reliable testing and faster iteration.
- Providing end-to-end lineage and observability for analytics and compliance teams to trace data provenance and debug data quality issues.
- Orchestrating machine learning feature and model pipelines (MLOps) including training, feature computation, and deployment steps with integrated testing.
- Migrating legacy cron or fragmented ETL jobs into a single, maintainable orchestration platform with reusable components and integrations.
- Deploying scalable production workflows on Kubernetes or managed Dagster Cloud to handle enterprise data workloads with enterprise support and controls.
- Authoring and orchestrating ETL/ELT pipelines and data assets
- Managing ML feature and model pipelines across dev/staging/production
- End-to-end data platform workflows with lineage and observability
- Testing and CI for data pipelines and transformations
- Deploying production-grade pipelines on Kubernetes or managed Dagster Cloud
