Nfig
Nfig is an agent API that turns natural language into browser actions so AI agents can browse, click, type, and finish tasks on live websites. You send instructions like open a page, search a product, or click a button, and Nfig runs them in a remote cloud browser through its Node.js SDK.
Generic web scrapers pull static HTML. Nfig targets interactive flows that need logins, pop-ups, file uploads, or changing page layouts, with self-healing steps when a site shifts structure. That focus on authenticated, resilient browser control is the trade-off: it is not a general LLM chat API, and it is built around step-based browser automation rather than bulk data extraction alone.
Developers building AI agents for sales demos, in-app customer training, or multi-site research are the core audience. The SDK connects to Playwright-backed remote sessions, docs live at docs.nfig.io, and signup runs through app.nfig.io with a Discord community for support.
Runs browser steps at $0.005 per standard step or $0.015 per Lite step on pay-as-you-go billing
Node.js SDK uses Playwright to control remote cloud browser sessions
Self-healing automations retry when a website layout changes mid-run
Scripts authentication flows for sites that require logins or pop-ups
Proxy usage billed at $12.5 per GB when routing traffic through Nfig
SOC 2 compliant with GDPR alignment stated on the Nfig security page
Ranked #3 Product of the Day on Product Hunt at launch
Natural language commands replace hand-written Playwright scripts for many flows.
Self-healing steps reduce breakage when target sites change layouts.
Pay-as-you-go billing avoids monthly lock-in for early experiments.
Handles authenticated sessions and pop-ups that break basic scrapers.
Node.js SDK and docs shorten integration time for agent builders.
Node.js is the only supported SDK language listed in the docs.
Per-step costs can add up on long multi-page automations.
The legacy nfig.ai domain is parked, so bookmarks to the old URL fail.
What does the Nfig API do?
Nfig lets AI agents act on live websites by turning natural language into browser steps such as navigation, typing, clicking, and scrolling. Developers call the Nfig SDK from Node.js to run those actions in remote cloud browsers.
How much does Nfig cost?
Nfig uses pay-as-you-go pricing with no monthly commitment. Standard steps cost $0.005 each, Lite steps cost $0.015 each, and proxy traffic costs $12.5 per GB. Authentication handling is included in the listed pricing.
Is Nfig free to start?
Nfig offers a free start path through app.nfig.io so developers can try the API before scaling usage. Ongoing use is billed per step rather than a flat subscription, according to the pricing section on nfig.io.
What SDK does Nfig support?
Nfig ships a Node.js SDK built on Playwright that connects to the Nfig Engine for remote browser execution. API reference and setup guides are published at docs.nfig.io for developers integrating agents.
Can Nfig handle logins and pop-ups?
Nfig includes tooling to script authentication flows and handle pop-ups, file uploads, and downloads during automations. That lets agents interact with sites that block simple scrapers or need an active session.
Where did Nfig move after nfig.ai?
The Nfig product now lives at nfig.io with docs at docs.nfig.io and signup at app.nfig.io. The older nfig.ai domain shows a domain-for-sale parking page and no longer hosts the service.
