It's a split decision.
YepAPI is a metered API for developers who want SEO, SERP, scraping, social, commerce and AI model endpoints behind one key. Hyperbrowser is a hosted browser and compute platform for agents that need Chrome sessions, isolated sandboxes or web data APIs. YepAPI has no monthly fee; Hyperbrowser has a free tier and paid plans starting at $30/month. Pick based on whether your application needs data and models or managed browser execution.

YepAPI Choose YepAPI if
- Choose YepAPI if you want SEO, SERP, scraping, social, and AI APIs under one key.
- Choose YepAPI if you prefer per-call billing without a monthly subscription.
- Choose YepAPI if your application needs structured JSON data rather than managed browser sessions.
Hyperbrowser Choose Hyperbrowser if
- Choose Hyperbrowser if agents need cloud-hosted Chrome controlled with Playwright or Puppeteer.
- Choose Hyperbrowser if workflows need isolated code execution and reusable sandbox snapshots.
- Choose Hyperbrowser if you need managed browser capacity, session recordings, or web extraction APIs.
02Pricing at real usage
YepAPI has no subscription or monthly minimum: the pricing page lists $5 signup credit, then per-call or other metered billing. Google SERP starts at $0.01 per call; scraping is $0.01 per call. Failed calls are not charged, and YepAPI says there are no rate limits.
Hyperbrowser's Free plan includes 5,000 credits, one concurrent session, and seven days of retention. Startup costs $30/month with 30,000 credits and $30 usage included; Scale is $100/month with 100,000 credits and $100 usage included. Additional credits cost $1 per 1,000. Usage can add browser time at $0.10/hour, proxy data at $10/GB, or sandbox compute at $0.045/vCPU-hour and $0.015/GiB-hour. Web fetch costs $0.001/page, with JSON adding $0.005/page. YepAPI suits irregular API calls; Hyperbrowser's base plan buys session capacity and a credit allowance.
03API, SDKs and integration
YepAPI exposes endpoints for SEO, SERP, scraping, social and commerce data, and 285 AI models. The homepage describes one API key and a consistent JSON response format. Scraping can return Markdown, HTML, or screenshots. The homepage links to the docs and llms.txt, and names Claude Code, Cursor, Codex, an MCP server, and agent skills as integration paths. It does not list a language-specific SDK in the published integration details, so check the docs for your client stack before building around a particular library.
Hyperbrowser combines browser sessions, sandboxes, and web data APIs. Its cloud Chrome sessions work with Playwright or Puppeteer; its listed SDKs include Node.js and Python, with a CLI and MCP integration. The Web API fetches, crawls, and searches, returning Markdown, HTML, screenshots, or schema-matched JSON. Agent workflows can run through HyperAgent, Browser Use, or computer-use models. Choose the API surface that matches your workload: data endpoints or browser control.
04Open source, self-hosting and lock-in
Neither vendor publishes an open-source license, self-hosting option, or defined data-export path. Both products are presented as hosted services, so plan for provider-specific API calls and account state rather than assuming you can move the service itself into your own infrastructure.
YepAPI's single key and consistent JSON responses can simplify endpoint switching within its catalog, but SEO, scraping, social, and model calls still use its routes and response schemas. Replacing them means mapping those calls and outputs to another provider. Hyperbrowser supports standard browser automation clients such as Playwright and Puppeteer, which can reduce changes to browser-control code. Its managed sessions, saved profiles, recordings, and sandbox snapshots still depend on Hyperbrowser's service model. Before adopting either for a long-lived system, confirm how you can retrieve stored outputs and migrate state.
Questions people ask
Which costs less for a small project?
It depends on usage. YepAPI has no monthly fee and bills by call or other metered unit, with $5 signup credit. Hyperbrowser has a free tier with 5,000 credits, then Startup costs $30/month. Compare the credit allowance and the specific endpoint or compute rates against your workload.
Does YepAPI provide browser automation?
YepAPI lists web scraping that can return Markdown, HTML, or screenshots, but does not list cloud browser sessions controlled through Playwright or Puppeteer. Hyperbrowser provides hosted Chrome sessions for those clients, as well as saved browser profiles and live session inspection.
Can Hyperbrowser replace YepAPI?
Hyperbrowser offers web fetching, crawling, search, and agent browser tasks. YepAPI also covers SEO and SERP data, social and commerce data, and a catalog of 285 AI models. A team considering a replacement should map each required endpoint and output format rather than treating the products as equivalent.
Which supports more concurrent browser sessions?
Hyperbrowser publishes concurrency figures by plan: one session on Free, 25 on Startup, 100 on Scale, and 1,000+ on Enterprise. YepAPI says it has no rate limits, but it is an API catalog rather than a managed browser-session service, so the limits describe different workloads.
