Jev Ultrafast: open-source Python browser agent library picks action and target in one request
An MIT-licensed browser agent library rebuilds an indexed element table on each observation and uses one TypeSafe request to choose both operation and target, reducing browser round trips, with a local demo and Python API.
Browser agents lose time when every decision turns into another browser round trip. Jev Ultrafast is a Python browser-agent repository for builders who want to run goal-driven browser tasks against real web controls. It helps you keep the agent loop lean by building a fresh, indexed table of visible elements for each observation, then choosing a supported operation and target from that state. Key features: • Dynamic action space – refreshes an element table and offers only supported operations and targets • One-request decisions – operation and target heads share the same observed state in one TypeSafe request • Text only when needed – a small LLM writes text only for `TYPE_TEXT` actions • Guarded execution – rechecks page freshness and click occlusion before browser input • Local demo + library API – inspect actions in a local UI or import `Agent` into a Python script It’s open-source (MIT license).
