Pluno

About Pluno

Pluno is a browser extension agent that automates tasks inside web applications by skipping the visual interface. Instead of clicking buttons and waiting for pages, it talks directly to the underlying APIs, getting work done in the background. The tool was benchmarked against Claude's browser extension on 312 real-world tasks across 24 apps and showed a 34% higher task success rate at roughly 14x the speed, according to its makers.

Review

Browser agents that rely on screenshots and simulated clicks often work slowly - they stare at screens, wait for DOM changes, and can get stuck in unexpected UI states. Pluno takes a different path. It executes actions by reverse-engineering the API calls a web app's own frontend makes, then reuses the user's existing login session to perform those calls locally from the extension. The result is a system that can handle a variety of SaaS chores without the overhead of visual interpretation.

Key Features

• API-first execution: directly calls backend endpoints the app's own UI uses, avoiding DOM interactions as the primary method.
• Local runtime: all tasks run inside the browser extension on your machine, keeping session tokens and data on your device.
• Cross-app chaining: moves data between separate web tools - for example, extracting attendee details from a conference site and importing them into Salesforce.
• Adaptive learning: inspects UI code to figure out how frontend-to-backend communication works for new or unfamiliar apps, then adopts the same pattern.
• UI fallback: when an app obscures its internal API paths (e.g., signed requests inside a web worker), the agent clicks through the interface to learn the flow, and subsequently reuses the discovered API calls.

Pricing and Value

During the launch period, new users receive $50 in free credits. The creators have not yet published a long-term pricing model or subscription details. As a result, the cost of regular use beyond the initial credits is unclear.

Pros

• Finishes tasks significantly faster than UI-driven agents - the makers report a 14x speed improvement in a controlled benchmark against Claude's browser extension.
• Works in the background without needing manual supervision of clicks and page loads.
• Builds its own understanding of an app's API by examining frontend code, so it can handle many web services with little pre-configuration.

Cons

• Cannot solve CAPTCHA challenges, so it won't work on sites that gate form submissions or logins behind them.
• The roadmap for paid plans isn't defined, leaving early users without a clear picture of future costs.
• Not well suited for people who need a visible, step-by-step click log for audits, as most actions happen out of sight via API calls.

Pluno may fit operators, founders, and small teams who spend chunks of their day on repetitive cross-tool data entry, bulk updates, or extraction tasks in standard SaaS apps. Those who need heavy visual oversight or work on sites with strict CAPTCHA requirements will likely bump into its limits quickly.
