A second architecture list focuses on the engineering systems beneath vibe coding: autonomous agents, browser runtimes, repository maps, crews, stateful graphs, and app-generation platforms.
Pattie Maes helped define the learning interface agent: software that observes users, adapts to their preferences, and takes limited initiative as a personal assistant.
Hyacinth Nwana's 1996 survey gave the exploding software-agent field a practical typology, distinguishing collaborative, interface, mobile, information, reactive and hybrid agents while warning that the word agent was being stretched too broadly.
OpenHands grew from the OpenDevin community into an open platform where software agents can edit code, run commands, browse the web and operate inside sandboxed environments across real engineering benchmarks.
How Katia Sycara and the RETSINA project turned multi-agent theory into reusable infrastructure for heterogeneous, cooperating software agents.
How ChatDev modeled software development as a sequence of conversations among specialized LLM agents for design, coding and testing.
