   const lc = new LevelChat({ apiKey: process.env.LEVELCHAT_API_KEY! });
   
   export async function mintToken(userId: string, roomId: string) {
     const { token, url, expiresAt } = await lc.rooms.issueToken(roomId, {
       identity: userId,
       displayName: "Alice",
       role: "publisher",
       capabilities: ["publish:camera", "publish:screen", "subscribe:all", "chat:send"],
       ttlSeconds: 600,

• How is LevelChat different from LiveKit?

  LiveKit is excellent for meetings. LevelChat spans meetings and interactive broadcast (50k concurrent viewers) under one SDK, with recording compression on egress and on-prem parity. We price per dimension so broadcast doesn't inherit meeting-shaped costs.

• Does LevelChat work without a server I run?

  Yes. Use managed cloud with an API key. You'll need a tiny server to mint tokens (10 lines) — never put your API key in the client.

• Can I self-host?

  Yes. Run the full 24-service stack with one docker compose command (Kubernetes Helm chart also published). Self-host customers get their own Studio admin panel at app.<your-domain>/console — same image we run in our cloud. Licensing is flat per-tier; see /self-host for the pricing.

• Is LevelChat open source?

  Partly. The 6 client SDK packages (web, react-native, flutter, ios, android, server-node) are MIT — true OSI open source, embed anywhere, any scale. The 14 server services ship under the LevelChat Community License (LCL) — source-available: read it, fork it, audit it, run it free under Community caps (1 room, 5 ppts, no recording). Production above those caps requires a paid license. Each release auto-converts to Apache 2.0 four years after publication. See /licensing for the full text.

• Can I resell LevelChat to my own customers?

  No — and this is intentional. Your paid Self-Host license lets you embed LevelChat as a feature inside YOUR product (an EdTech platform, a telehealth app, a SaaS), and that product can be sold freely. What the license forbids (LCL §3.2) is operating LevelChat as a service for third parties — white-labelling it as "Acme Video Cloud" and reselling capacity to people who never heard of LevelChat. Each license is bound to one cluster fingerprint, and the heartbeat surfaces lifted licenses within minutes. If you want a true OEM/reseller arrangement, talk to sales — that's an Enterprise-tier addendum, not a standard Self-Host license.

• Does LevelChat support end-to-end encryption?

  Yes. The SDK ships sFrame-ready insertable-streams transforms on every sender and receiver. Call room.setEncryptionKey() and frames flow encrypted E2E — the SFU forwards opaque payloads it can't decode. Available on every tier including self-host Pro.

• What about GDPR and EU data residency?

  Default region is EU (Frankfurt). Pick region: "eu" when you create a room and no packet leaves the EU. We sign a GDPR DPA at contract time. Our managed cloud runs primarily on Hetzner in Germany and Finland.

• What about HIPAA?

  We sign a BAA on the Scale and Enterprise tiers. PHI is never logged; recordings are encrypted at rest (customer-managed KMS on Enterprise).

• How does pricing scale?

  Two meters — participant-minutes for meetings, viewer-hours for broadcasts. Both have generous bundled amounts per tier, and overages are published per unit. We email you at 75%, 90%, and 100% of any cap.

• Can I migrate from Twilio Video?

  Yes. npx levelchat migrate twilio scans your repo, finds twilio-video imports, and emits a diff PR. Twilio's EOL is December 2026; our tool is free whether you pick us or not.

• What's the codec story?

  AV1 + SVC by default for cameras and screen share. H.264 fallback is negotiated automatically for older clients. We re-encode server-side for low-power senders, so your users don't pay the AV1 CPU cost.

• How many concurrent viewers does broadcast support?

  Up to 50,000 concurrent viewers per room on our standard tiers. Enterprise can go higher with multi-CDN fan-out.

• What does "unified SDK" mean in practice?

  The same Room, Track, and Participant primitives work whether you're doing a 1:1 support call, a 50-person classroom, or a 10k-viewer product launch. You can promote a call to a broadcast with room.promote("broadcast") mid-session.
