[swiftide](https://swiftide.rs) reports 774 GitHub stars, 69 forks, and 18 open issues, last pushed Aug 19, 2026. [haystack](https://haystack.deepset.ai) has 26k stars, 3.0k forks, and 108 open issues, last pushed Aug 1, 2026. Figures are from public GitHub metadata via [swiftide's repository](https://github.com/bosun-ai/swiftide) and [haystack's repository](https://github.com/deepset-ai/haystack). | | [swiftide](/tools/bosun-ai-swiftide.md) | [haystack](/tools/deepset-ai-haystack.md) | | --- | --- | --- | | Tagline | Fast, streaming indexing, query, and agentic LLM applications in Rust | Open-source AI orchestration framework for building context-engineered LLM applications. | | Stars | 774 | 26,073 | | Forks | 69 | 2,972 | | Open issues | 18 | 108 | | Language | Rust | Python | | Adopt for | Swiftide, built in Rust, offers a specialized solution for developing fast and efficient streaming applications related to AI agents and LLM operations. | Haystack is an open-source AI orchestration framework for building context-engineered LLM applications. | | Persona | - | - | | Runtime | - | - | | License | MIT | Apache-2.0 | | Categories | AI Agents, Data & Retrieval, LLM Frameworks | AI Agents, Data & Retrieval, LLM Frameworks | ## Trust and health _Sourced signals - not a safety guarantee.

The repository is open-source under the MIT License. - **Adopt for:** Swiftide, built in Rust, offers a specialized solution for developing fast and efficient streaming applications related to AI agents and LLM operations. ## 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 ## Choose when ### Choose swiftide if… - swiftide is primarily Rust; haystack is Python. - License: swiftide is MIT, haystack is Apache-2.0. - Pricing: No pricing information provided. The repository is open-source under the MIT License.. - Tags unique to swiftide: data, genai, indexing, llm. - - You are working with real-time data streams and need a solution that supports high-speed indexing and querying. ### Choose haystack if… - haystack is primarily Python; swiftide is Rust. - License: haystack is Apache-2.0, swiftide is MIT. - 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, gemini, generative-ai, gpt-4. - You need explicit control over retrieval, routing, memory, and generation within your LLM application pipelines. ## When NOT to use swiftide - - Your project primarily involves batch processing, without a need for real-time streaming support. - - If you prefer a language other than Rust, as Swiftide does not offer an alternative implementation. ## 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. ## Common questions ### What is the difference between swiftide and haystack? swiftide: Fast, streaming indexing, query, and agentic LLM applications in Rust. haystack: Open-source AI orchestration framework for building context-engineered LLM applications..
