After watching developers struggle with context switching between terminals, dashboards, and IDEs while building voice AI, we knew there had to be a better way. The Vapi CLI eliminates the friction. Want to add voice AI to your existing React app? vapi init and you're coding. Need to test webhooks? vapi listen and skip ngrok entirely. Tired of your IDE hallucinating our APIs? vapi mcp setup gives it perfect knowledge. We've supported a ton of tech stacks from day one because voice AI should work with your existing workflow, not against it. Install in 10 seconds: curl -sSL | bash
Congrats on the launch Dan!!

 Thanks Tim!

Awesome company, awesome product.

 proud to be giving technology voice :)

Laid out really nice. Took me a while to find the scrollbar, could be lack of sleep.

🫡🫡🫡 Another fantastic launch gj man

Maker

 thanks Christian 🐐

I really love your graphics for this launch. They are very cool and unique. But most important: Congrats on launching! Building a technical product takes time, perhaps even more than a "usual" typical product, so even more congrats haha

 Thanks Ernest. Launches indeed take a lot of love!

@VapiAI 🚨 CODE RED CHALLENGE:

Deploy Twilio+Next.js voicebot in ≤10 mins under THESE CONDITIONS:

• 2014 MacBook Air (1.4GHz) running Windows XP via Bootcamp

• Starbucks WiFi during lunch rush 🔥

• While I npm install -- global legacy-peer-deps

SUCCESS? Your CTO does 1:1 mentoring + boba for my WHOLE COMPANY 🧋🏢

FAIL? We livestream the fail to 10k devs (with reacts)

⏳ LIVE COUNTDOWN: 09:57...09:56... #DoOrDieDX

This goes so hard, can't wait to test it out! Any helpful tips for integrating this with existing applications?

just run vapi init in your project and you’re done ;)

Really excited to dive into the voice AI space, and Vapi looks like the perfect launchpad. The fact that it abstracts away the heavy lifting around voice infra, latency, and LLM integration is huge for someone new to this area. Love how developer-friendly it seems right out of the box—will definitely be exploring it as I start building. Great work to the team!

Local webhook debugging is the feature that stands out to me. Testing voice flows usually means deploying just to see what broke, so being able to catch it on your own machine first saves a lot of round trips. Turning the IDE into a Vapi expert through MCP is a nice touch too. How does it handle simulating inbound calls during local testing?
