The package has now been archived and is no longer maintained. Most experiments\u2014including Agent, AsyncPipeline, Tool calling, multimodality support, and Human-in-the-Loop features\u2014have graduated into haystack-ai itself. A smaller set of experiments were discontinued entirely and exist only in this final release.\n\nThe 0.19.0.post1 release is frozen and will receive no updates, bug fixes, or compatibility patches. It depends only on haystack-ai and supports Python 3.10 through 3.13. If you need an experiment that graduated, use haystack-ai instead. If you depend on a discontinued experiment, you must pin this package explicitly and accept that it will drift out of sync with newer haystack-ai releases over time.","worth_installing":"No, unless you have legacy code that depends on a discontinued experiment and cannot migrate to haystack-ai. The package is archived, abandoned, and will not be maintained. Any new Haystack work should use haystack-ai directly. If you do install, pin to 0.19.0.post1 explicitly and understand that compatibility with future haystack-ai releases is not guaranteed."},"id":"haystack-experimental","links":{"html":"https://skillfed.io/packages/haystack-experimental","md":"https://skillfed.io/packages/haystack-experimental.md","pypi":"https://pypi.org/project/haystack-experimental/"},"maintenance":{"status":"abandoned"},"meta":{"latest_release":"2026-07-28","license_spdx":null,"license_treatment":"permissive","name":"haystack-experimental","python_support":"supports_current","summary":"Experimental components and features for the Haystack LLM framework."},"popularity":{"monthly_downloads":713714,"position":5250,"tier":"top_15000"},"security":{"n_vulnerabilities":0},"version":"0.19.0.post1"}
