Plasmate is an open-source (Apache 2.0) browser engine for AI agents that produces the Semantic Object Model (SOM) — a flat, typed JSON document representing a web page in a form optimized for LLM consumption. This integration adds PlasmateWebFetcher and PlasmateSOMConverter components for Haystack 2.0 RAG pipelines as a drop-in alternative to LinkContentFetcher and HTMLToDocument, with ~17x average token reduction across the public WebTaskBench benchmark. Reopening the redirect from deepset-ai/haystack#11056 (closed Apr 13 with @anakin87 suggesting this venue). Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

Adds the Plasmate integration to the showcase.
Following @anakin87's suggestion in deepset-ai/haystack#11056 — that PR proposed a
PlasmateFetcherdirectly inside the Haystack core, which @anakin87 redirected here. The integration package itself already lives atplasmate-labs/haystack-plasmate(Haystack 2.0 components:PlasmateWebFetcherandPlasmateSOMConverter).What Plasmate is
Open-source (Apache 2.0) browser engine that produces the Semantic Object Model (SOM) — a flat, typed JSON representation of a web page optimized for LLM consumption. Drop-in alternative to
LinkContentFetcher/HTMLToDocumentthat delivers an order of magnitude lower token cost per page.Public benchmark (38 sites, weekly updated): https://webtaskbench.com — currently 29.6× average compression, 9.8× median, 118.5× peak (cloud.google.com).
