YaCy's core architecture with the PLASMA search engine, the http server/proxy, the KELONDRO Database and the P2P-based index distribution was designed and implemented by Michael Peter Christen.

At this time, many contributions have been made:

• Alexander Schier did much alpha-testing, gave valuable feed-back on my ideas and suggested his own. He suggested and implemented large parts of the popular blacklist feature. He supplied the 'Log'-menu function, the skin-feature, many minor changes, bug fixes and the Windows-Installer - version of YaCy. Alex also provides and maintaines the german documentation for yacy.
• Martin Thelian made system-wide performance enhancement by introducing thread pools. He provided a plug-in system for external text parser and integrated many parser libraries such as pdf and word format parsers. Martin also extended and enhanced the http and proxy protocol towards a rfc-clean implementation.
• Roland Ramthun owns and administrates the German YaCy-Forum. He also cares for correct English spelling and a German translation of the YaCy user interface. Roland and other forum participants extended the PHPForum code to make it possible to track development feature requests and bug reports with status codes and editor flags.
• Marc Nause made enhancements to the Message- and User-Profile menues and functions.
• Natali Christen designed the YaCy logo.
• Thomas Quella designed the Kaskelix mascot.
• Wolfgang Sander-Beuermann, executive board member of the German search-engine association SuMa-eV and manager of the meta-search-engine metaGer provided web-space for the german documentation and computing resources for a demo peer. He also pushed the project by arranging promotional events.
• Timo Leise suggested and implemented an extension to the blacklist feature: part-of-domain matching.
• Martin Schwarze wrote a artikel/press release "Jedermanns Suchmaschine" about the YACY Projekt; published in the Hannoversche Allgemeine Zeitung.
• Matthias Kempka provided a linux-init start/stop - script
