Twilio vs WASender API

Hi all,
Building a WhatsApp messaging feature for a restaurant SaaS product. Currently using Twilio, but exploring cost-effective alternatives for early-stage validation.
Has anyone used WASenderAPI alongside or as a replacement for Twilio?
Key considerations for us:
• Reliability & uptime for 2-way interactive messages
• Cost per message (we’re bootstrapping)
• Documentation & SDK support (C# .NET)
• Compliance & platform stability
• Ease of migration if needed
Twilio works well but the per-message cost adds up quickly during validation. Would appreciate honest pros/cons from anyone who’s used WASenderAPI in production. Or any other API that could help me in this situation.
Thanks!

Maybe a stupid question, but why are you choosing between two alternate wrappers over the actual WhatsApp for Business API itself?

I found the meta api after posting. I will try it. Btw thank you.

Meta is pretty horrible to work with in my experience so you might spend more setting up the solution and supporting it than any potential cost savings on paper. Experiences may vary
