Most WhatsApp Tools Are Built to Break

The majority of WhatsApp automation tools rely on risky APIs or cloud relays that lead to instant account bans. We built SLTD - WA Sender to operate **inside the browser context**, mimicking exact user interactions.

Stability and account integrity are our core principles.

  • Native Store Injection Directly interacts with WhatsApp's internal Webpack modules.
  • No Third-Party Relays Your data never touches an external server. 100% local.
  • Human-Mimicry Flow Simulates delays and natural typing patterns to stay under the radar.
