ApodexAI/FrontierAgent was created 2026-08-22 and is at 1,199 stars with 100 forks and commits through 2026-08-28. It is an Apache-2.0 agent runtime, terminal TUI and evaluation suite for long-horizon file-based work, shipping two native workflows: ReAct (one stateful agent in a task-scoped sandbox) and Agent Team (a coordinator with a task board delegating to parallel sub-agents). The notable part for builders is that the same workflow engine powers the benchmark runner Apodex uses to evaluate its own models, with a tech report at arXiv:2608.23283, so the eval layer and the product layer are the same code.
