# haystack vs aqueduct

*GraphCanon updated Aug 3, 2026*

## Verdict

Pick haystack if haystack is an open-source AI orchestration framework for building context-engineered LLM applications; pick aqueduct if aqueduct is a deprecated Go-based tool for orchestrating LLM and ML workloads across various cloud infrastructures with Kubernetes support.

[haystack](https://haystack.deepset.ai) reports 26k GitHub stars, 3.0k forks, and 108 open issues, last pushed Aug 1, 2026. [aqueduct](https://aqueducthq.com) has 517 stars, 20 forks, and 11 open issues, last pushed Jun 7, 2023. Figures are from public GitHub metadata via [haystack's repository](https://github.com/deepset-ai/haystack) and [aqueduct's repository](https://github.com/RunLLM/aqueduct).

## Decision facts: haystack

- **Pricing:** freemium - Free and open-source under the Apache-2.0 license, but users have to manage their own infrastructure and resources.
- **Requirements:** Min 4 GB RAM; Requires Docker
- **Adopt for:** Haystack is an open-source AI orchestration framework for building context-engineered LLM applications.
- **License detail:** Apache-2.0

## Decision facts: aqueduct

- **Adopt for:** Aqueduct is a deprecated Go-based tool for orchestrating LLM and ML workloads across various cloud infrastructures with Kubernetes support.

## Choose when

### Choose haystack if…

- haystack is primarily Python; aqueduct is Go.
- Pricing: Free and open-source under the Apache-2.0 license, but users have to manage their own infrastructure and resources..
- Requirements: Min 4 GB RAM; Requires Docker.
- Tags unique to haystack: agent, agents, gemini, generative-ai.
- Also covers AI Agents, Data & Retrieval.
- You need explicit control over retrieval, routing, memory, and generation within your LLM application pipelines.

### Choose aqueduct if…

- aqueduct is primarily Go; haystack is Python.
- Tags unique to aqueduct: data, data-science, kubernetes, llm.
- Also covers Inference & Serving, Model Training.
- When you need to deploy legacy workflows that depend on Aqueduct's specific implementation of custom ops for resource allocation and training.

## When NOT to use haystack

- You require integration with specific proprietary tools or frameworks not supported by Haystack.
- Your development team is not familiar with Python-based technologies, since Haystack primarily supports Python-based workflows.
- You are looking for a completely managed service rather than an open-source framework that requires more hands-on configuration and customization.

## When NOT to use aqueduct

- Avoid if active project maintenance or community support is required as Aqueduct is no longer maintained.
- Skip this tool for new projects focusing on state-of-the-art ML orchestration, opting instead for actively supported alternatives.
