Cloud browsers and web APIs for AI agents
Spin up scalable, sandboxed headless browsers on demand and drive them with Playwright, Puppeteer, Selenium, or the Stagehand framework.
Find relevant websites from a single query and convert any URL into clean HTML, JSON, or markdown built for LLM context.
Authenticate agents and get through login walls, CAPTCHAs, and anti-bot systems so workflows do not stall mid-task.
Inspect sessions with live view, replay, structured logs, and debugging across prompts, model calls, and browser actions.
Cold email infrastructure that actually reaches the inbox
Purchase or connect domains, auto-generate mailbox names, and get Google or Microsoft 365 accounts created, authenticated, and connected to your outreach platform in minutes.
SPF, DKIM, DMARC, and custom tracking domains are configured automatically with health checks, so you skip the manual DNS work that usually breaks deliverability.
Export mailboxes directly into Instantly, Smartlead, ReachInbox, Reply, Lemlist, and 50+ other outreach tools without manual credential juggling.
Run separate workspaces per client or campaign, with one domain per workspace so sending reputations stay isolated and manageable at scale.
