Comparison
Opaige vs CheckVisaSlots — infrastructure vs alert tool.
CheckVisaSlots pioneered the US-visa slot-alert category with a free Chrome extension and optional human bookers at $75 flat. That works for individuals on consumer desktops. Opaige is architecturally different: a server-side orchestrator with residential IPs, captcha solvers, a state machine, and an API — built so platforms, agencies, and power users get guaranteed execution without babysitting a browser tab.

When to pick which
Honest guidance
Pick CheckVisaSlots if
- • You only need US visa interview slots
- • You're happy to keep a Chrome window open on a powered-on machine
- • You want a free alert tool and will book manually yourself
- • You're OK paying $75 flat for a human agent to book on your behalf
Pick Opaige if
- • You need VFS Global or TLS Contact (Schengen, UK, etc.)
- • You want booking to run without your laptop being on
- • You're a travel agency, EOR, or relocation platform — you need an API
- • You have volume and want monthly pricing, not per-booking human fees
- • You need evidence bundles (screenshots + PDFs) for client records
How it works
The architectural difference
CheckVisaSlots
A Chrome extension runs inside your browser. It polls the portal from your own IP on your own machine. When a slot appears, it alerts you (or escalates to a human agent on the paid flat-rate tier) — then you or the agent manually log in and book. Shut the lid and everything stops.
Opaige
A fleet of server-side Playwright workers on residential IPs runs 24/7. Each booking lives in a durable state machine (BullMQ + Postgres). When a slot is found, the same worker holds it, handles the OTP via a real-time channel back to you, submits, and emits a webhook with the confirmation. Your laptop can be off.
