Our commitment
Independent research methodology
Our researchers use a mix of verified reviews, independent research, and objective methodologies to bring you selection and ranking information you can trust. While we may earn a referral fee when you visit a provider through our links or speak to an advisor, this has no influence on our research or methodology.
Verified user reviews
GetApp maintains a proprietary database of millions of in-depth, verified user reviews across thousands of products in hundreds of software categories. Our data scientists apply advanced modeling techniques to identify key insights about products based on those reviews. We may also share aggregated ratings and select excerpts from those reviews throughout our site.
Our human moderators verify that reviewers are real people and that reviews are authentic. They use leading tech to analyze text quality and to detect plagiarism and generative AI.
How GetApp ensures transparency
GetApp lists all providers across its website—not just those that pay us—so that users can make informed purchase decisions. GetApp is free for users. Software providers pay us for sponsored profiles to receive web traffic and sales opportunities. Sponsored profiles include a link-out icon that takes users to the provider’s website.

Haystack by deepset overview
What is Haystack by deepset?
Haystack is an open-source AI orchestration framework developed by deepset, designed for building production-ready pipelines that power search, question answering, retrieval-augmented generation (RAG), and other NLP-driven applications. Haystack supports integration with a wide range of large language models, vector databases, and document stores, giving engineering teams the flexibility to compose modular pipelines tailored to specific use cases across industries such as legal, finance, healthcare, and enterprise IT.
Haystack's pipeline architecture is built around interchangeable components — retrievers, readers, generators, and routers — that can be configured and chained to handle complex multi-step workflows. Deployment options include local environments, cloud infrastructure, and containerized setups, making it suitable for teams ranging from research-focused startups to large-scale enterprise operations. Native support for REST APIs and compatibility with major ML frameworks accelerates the path from prototype to production without requiring significant infrastructure overhead.
