Nfig vs Agent.so

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.

Agent.so puts hundreds of role-specific AI agents and a custom agent builder behind one login. You chat with pre-built experts spanning marketing, coding, tutoring, and dozens of other fields, create your own agents in seconds without code, and train them on your files, links, and sitemaps. The platform routes chats through models from OpenAI, Anthropic, Google, Meta, xAI, DeepSeek, and other labs so you are not tied to a single chatbot subscription.

Most agent builders hand you a blank canvas and expect you to wire prompts yourself. Agent.so front-loads the library with 250+ ready-made agents, an Apps Hub for one-shot tasks like subject lines and ad copy, and a Shards currency for pay-as-you-go access to advanced models and skills. That structure suits people who want specialist chats on day one rather than a week of setup.

Freelancers, consultants, and small teams use Agent.so for marketing drafts, coding help, and training agents on client knowledge bases. Agent Plus costs $19 per month at the early-access rate (regular $29) and includes unlimited messages, custom agent training, and 3,000 monthly Shards. A free tier remains available with conversation depth limits and caps on how many custom agents you can run at once.
