Nimbus

About Nimbus

Nimbus is an agentic browser that executes web tasks from plain-English instructions. It automates mechanical interactions like clicks, form fills and file handling, and is built from the ground up rather than as a browser extension.

Review

Nimbus aims to reduce repetitive browser work by letting an agent perform multi-step tasks across tabs while pausing only for decisions that require your input. The app emphasizes session-based workflows, local traces, and support for user-supplied model keys so you control the LLM provider used.

Key Features

• Agent-driven automation of clicks, form entries, file pickers and multi-tab coordination.
• Session management so each task has its own tab set and history, and can run in the background.
• Ask-user tool that pauses tasks for judgment calls through the chat interface rather than page overlays.
• Skills to capture and reuse flows, and auth handoff so manual logins resume the agent afterward.
• Local-first traces and a bring-your-own-key model so LLM calls go directly to your chosen provider.

Pricing and Value

Nimbus launched with a free offer for the first 500 founding users forever and provides a macOS download for early adopters. Beyond that founding allocation, explicit tiered pricing is not listed on the launch page; value is strongest for users who frequently spend time moving files, copying data between sites, or filling complex forms, since the agent can reclaim that time. The bring-your-own-key approach means you may incur costs from your chosen LLM provider rather than from the app itself.

Pros

• Reduces repetitive, multi-tab web work by automating routine interactions.
• Built as a standalone app rather than an extension, avoiding some extension limitations.
• Sessions and skills make it easier to organize and reuse workflows.
• Local traces and direct LLM connections improve transparency and control over data flow.
• Pauses for user decisions help prevent incorrect or unsafe automation choices.

Cons

• Very early-stage launch means features and stability may evolve; expect occasional rough edges.
• Initial availability targets macOS, so other platforms may be unsupported at first.
• Requires supplying your own LLM key for full functionality, which can add cost and configuration work.

Nimbus is best suited for users who spend significant time on browser-based workflows-data collection, form-heavy dashboards, or repetitive upload/download sequences-and who want to offload the mechanical steps. Early adopters who can tolerate an evolving product and who can supply their own LLM key will get the most out of the current offering; the free founding-user allocation makes it easy to try without upfront cost.
