Dropping Callforge to $99 for 48 hours. Voice-agent SaaS boilerplate (Vapi/Retell + Stripe billing) that'd take you 2 weeks to wire. Ends Aug 31. callforge.dev/calculator

Fixed the calculator link, was serving the wrong page before. Live now: callforge.dev/calculator - real published pricing across Vapi/Retell/Bland/Twilio/OpenAI Realtime. Feedback welcome.

Built a voice-agent cost calculator for Vapi, Retell, Bland, and Twilio + OpenAI Realtime. Shows the runtime bill and the billing plumbing it leaves out. callforge.dev/calculator #voiceai

Stripe's API docs are the blueprint every dev tool secretly copies. The 'try it here' code block? Not a toy. It's the moment devs stop reading and start believing. Teardown: dev.to/mattewens/why-stripes-api-do… #devtools #api

Wrote a small teardown of Vercel's pricing page — why 'Hobby' as a tier name does more emotional work than any headline. Not free positioning. It's an invitation. Full read: dev.to/mattewens/how-vercels-pricin… #saas #pricing #webdev
