Problem

Smooth addresses the difficulty of making software reliably operate websites like a human: navigating interfaces, logging in, extracting information, completing forms, testing pages, and carrying out workflow actions. These tasks are often brittle because they depend on changing web interfaces and require browser infrastructure, session management, proxies, and CAPTCHA handling. The main use case is giving developers a way to automate web tasks—including scraping behind logins, retrieving invoices, getting quotes, testing pages, and automating social-media actions—without building that browser-operations stack themselves.

The pain has a direct economic dimension: slow or failed browser runs increase compute costs and make automation unsuitable for production or high-volume use. Smooth reports that its average WebVoyager task takes 1.4 minutes versus 7.5 minutes with Browser Use, while running the full benchmark costs $38 versus $250. These figures are company-reported, but they clearly express the product's intended value proposition: reliable browser execution at lower latency and substantially lower cost.

Product / Service

Smooth is a serverless browser-agent API. An application submits a natural-language task through the REST API or an SDK, and Smooth launches a browser agent that performs actions autonomously using the web's normal interfaces. Developers can run one-shot tasks that return results or create persistent, interactive sessions for multi-step workflows; they can also add custom tools, structured outputs, browser profiles, file uploads, and other application-specific capabilities.

The delivery model is plug-and-play and infrastructure-light: users obtain an API key, launch a task with a small amount of code, and let Smooth manage browser spin-up, proxy configuration, persistent sessions, CAPTCHA solving, polling, error handling, and scaling. Smooth positions this as production infrastructure that can scale from individual runs to millions of executions, with enterprise security, dedicated support, single-tenant, BYOC, and on-premise deployment options.

Market

Smooth competes in the emerging AI browser-agent and serverless browser-automation API market, overlapping with web scraping, workflow automation, and browser-based QA/testing. Its clearest named competitor is Browser Use, against which Smooth markets lower cost, faster execution, and higher reliability. More broadly, it competes with browser automation frameworks and other agents that allow software to interact with websites, but the public company materials do not provide a complete competitor list.

The company appears to be an early-stage, YC-backed startup rather than a mature scaled vendor. Y Combinator lists Smooth as founded in 2024, part of its Fall 2024 batch, active, with a two-person team; the company offers a free starting plan, paid-plan support, demos, and an enterprise deployment path. The public sources reviewed do not disclose revenue, customer counts, or conversion metrics, so Smooth should not be labeled definitively pre-revenue; its publicly visible traction is its active YC status, launched API, free self-serve availability, and ongoing hiring rather than demonstrated commercial scale.
