Reviewer scorecard
“Essential for dev teams. GitHub, CI, and alerting integrations make it the nervous system of any engineering org.”
“The gold standard for communication APIs. Well-documented, reliable, and battle-tested at every scale imaginable.”
“It's bloated and expensive at scale, but there's no real alternative that matches its ecosystem. Reluctant ship.”
“Expensive at volume but the developer experience and reliability justify the cost. Vonage and others still lag behind.”
“Canvas, clips, and huddles have made it more than just chat. Great for async creative collaboration.”
“Twilio's pivot to customer engagement platform positions them well, but the core APIs remain their moat.”
