What is Agora RTC?
A practical answer on agora rtc, written from projects I have actually shipped rather than from a spec sheet.

Agora Real-Time Communication (RTC) provides SDKs and building blocks to add real-time voice and video calling capabilities to applications.
In More Detail
You call it with a channel name and a short-lived token, and the SDK deals with codec negotiation, echo cancellation, and adapting bitrate to whatever connection each participant actually has. The token has to be minted by your own server from a secret Agora issues you, which is what stops anyone who has read your app bundle from joining a call they weren't invited to.
The trade-offs are commercial rather than technical. Billing is by usage, so cost scales with call minutes and with video resolution in a way that needs modelling before you commit to a pricing plan of your own. You are also dependent on their availability and their SDK's release cycle. In exchange you skip running media servers, which is a genuinely specialised operational job.
What This Means For Your Project
This is what I used to build a production video-calling platform — worth it specifically when you need reliable, low-latency calling without maintaining your own media server infrastructure.
If this came up while you were scoping a project: the services page lists what I build, pricing publishes real starting figures, how I work covers cadence and timezone overlap, and the case studies show the stack and timeline on eight real projects. Unfamiliar term? Try the glossary.
