LiveKit, Agora, and Daily all hand a developer the same primitive: a real-time audio and video room that code can join. They sell that primitive three different ways, and the difference changes what your team operates, what your bill looks like, and where the telephony bridge ends up living. This post compares the three on their own published terms, then asks the question that actually decides the shortlist: is real-time media a component you embed, or a platform you buy?
Quick answer: LiveKit is the open-source SFU route: you run the media server yourself under an open-source licence, or consume LiveKit Cloud and let the vendor run it. Agora is the managed-network route: a proprietary global real-time network billed per usage-minute, with the broadest SDK matrix of the three. Daily is the browser-first route: prebuilt call objects and embed components that get a room onto a web page fastest, priced per participant-minute. All three are frameworks for real-time media, not communications platforms: none ships the PSTN and WhatsApp bridging, the messaging channels, or the customer record that sit around a customer-facing video workflow. That gap is the build-vs-buy fork this post closes on.
1. Three postures on real-time media
LiveKit: the open-source SFU. LiveKit's server is an open-source selective forwarding unit you can deploy on your own infrastructure, with LiveKit Cloud as the hosted alternative. Its Agents framework lets code participants join a room as media peers, which has made it a common substrate for voice and video agents. Choosing LiveKit is choosing to own, or deliberately hand off, the media plane.
Agora: the managed real-time network. Agora runs a proprietary software-defined real-time network and sells minutes on it. The SDKs cover the widest device matrix of the three, and the commercial shape is usage: voice minutes and video minutes on a published rate card. Choosing Agora is choosing a managed network with no server to operate and no source to read.
Daily: the browser-first embed. Daily optimizes for the shortest path from SDK to a rendered call: a prebuilt call UI and embed components aimed at web products adding video. Choosing Daily is choosing developer speed on the browser surface, with the back-end kept deliberately thin.
2. The dimension matrix
| Dimension | LiveKit | Agora | Daily |
|---|---|---|---|
| SFU architecture | Open-source SFU you self-host, or hosted on LiveKit Cloud [1] | Proprietary managed real-time network; no server to run [2] | Managed infrastructure behind a browser-first API and prebuilt UI [3] |
| Recording | Egress service publishes rooms to object storage or RTMP; self-hosted, the storage is yours [1] | Cloud recording priced as an add-on on the published rate card [2] | Cloud recording on the published rate card [3] |
| SIP / telephony interconnect | SIP support documented for bridging rooms to PSTN trunks; the trunk and carrier remain yours [1] | SIP extension documented as an add-on for PSTN connectivity [2] | SIP interconnect documented for dial-in and dial-out [3] |
| Regions / PoPs | LiveKit Cloud regions published; self-hosted, the server lives where you put it [1] | Managed network the vendor describes as spanning 200+ countries and regions [2] | Global edge network per the vendor's public documentation [3] |
| Pricing shape | Open-source server free to run; LiveKit Cloud on a published rate card with a free tier [1] | Per-minute rate card with a published free monthly allotment [2] | Per-participant-minute rate card with a published free tier [3] |
The competitor cells reflect each vendor's published pricing and documentation pages, accessed October 2026; the numbered sources are listed at the end of the post. The matrix deliberately carries no latency benchmarks: round-trip times depend on your regions, your client mix, and your network path, and any vendor's headline number should be treated as a starting point for a measurement, not a fact.
The row that matters most is the third. Every one of the three documents a way toward the phone network, and none of the three makes it the center of the product.
3. The telephony-bridge question
A customer-facing video room almost always ends up needing the phone network: a participant dialing in from a PSTN number, an outbound leg to a SIP trunk, a WhatsApp or SMS thread that surrounds the session. The three vendors place that bridge in three different locations, and all three leave part of it on your side.
On LiveKit, SIP is a documented integration: rooms can bridge to PSTN trunks through the platform's SIP support. The trunk itself, the number inventory, and the carrier relationship are infrastructure you source and operate, which is a natural fit next to LiveKit's self-host posture and a real operations line item beside it.
On Agora, the SIP extension is the documented path to PSTN, sold as an add-on to the minute-based core. The shape is managed, but the telephony leg is still a separate commercial and configuration conversation from the video minutes.
On Daily, SIP interconnect covers dial-in and dial-out, again as an adjacency to the core embed rather than as the core's home.
And WhatsApp is not an RTC problem at all: it is a messaging-platform contract with its own template and consent rules, and none of the three vendors sells it as part of the room. Whichever framework you pick, the bridge is a build-or-integrate project that lands on your team.
4. When embedded video wins: the disclosed frame-in
This section is the disclosed Orbit frame-in; the preceding comparison is the vendor-vs-vendor analysis. Devotel Orbit takes the opposite posture on the bridge question: the room and the channels around it live on one account, so the telephony and messaging legs are platform capability rather than integration projects. Orbit's voice path runs SBC routes on jambonz, the open-source session border controller, so a video room can reach the PSTN and SIP trunks a tenant already operates without a second vendor relationship.
The buy side of the fork gets concrete when the room is customer-facing rather than infrastructure. Three things shipped on Orbit in October 2026 mark the shape: a room picker for the embeddable video widget, captions validated at save on room templates, and webinar registrant cards that sync on save. Webinars with registrant sync, captions you can trust before the session starts, and a picker a non-engineer can configure are not SDK features; they are product surface on top of the room. The same account carries the AI lane: video avatar agents that join a room as rendered participants, alongside programmable voice, SMS and MMS, WhatsApp, email, and the contact center, on one usage-based bill.
The honest fit stays with the frameworks when the requirement is infrastructure-shaped. If your team needs to self-host the media server for compliance, white-label the stack under your own brand, or treat real-time media as a component inside a larger product, LiveKit's open-source SFU, Agora's managed network, and Daily's browser-first embed are each a correct answer on their own terms. If the room is the customer experience rather than a component in it, the embedded route means buying the bridge, the channels, and the record separately, and stitching them.
The neutral next reads are the pairwise comparisons: Orbit vs LiveKit, Orbit vs Agora, and Orbit vs Daily, with the matrices on the LiveKit, Agora, and Daily comparison pages, and the shipped capability list on Orbit's RTC feature page.
5. Where each vendor lands
Choose LiveKit when the media plane is yours to own. An engineering team that wants source access, self-hosting, and code participants in the room gets a real product with a real community. Budget for the trunk, the egress storage, and the operations of the server itself.
Choose Agora when the network is the product. A team that wants managed global real-time minutes across the widest device matrix, with no media server to run, gets the most mature managed network of the three. Budget for the add-ons that sit beside the minutes.
Choose Daily when the browser embed is the whole requirement. A product adding in-browser video fastest gets the shortest path to a rendered call. The thinner the back-end requirement, the better the fit.
Choose the embedded route when the room is customer-facing. Webinars with registrants, captions, PSTN participants, and surrounding messages are a platform requirement, and the migration path into Orbit is the same shape as any video-platform move: un-embed the vendor room, embed Orbit's, and let the telephony and messaging legs land on the same account. The Vonage Video migration runbook is the closest worked example: inventory the rooms and trunks, stage the cutover, and move traffic in reversible waves.
Frequently asked questions
Which of the three is open source?
LiveKit. Its server is open source and self-hostable, with LiveKit Cloud as the hosted option. Agora and Daily are managed services with no self-host path.
Can any of the three connect a room to the phone network?
All three document a SIP path: LiveKit's SIP support, Agora's SIP extension, and Daily's SIP interconnect. In each case the trunk, the numbers, and the carrier relationship are a separate sourcing and operations decision from the video platform.
Which is fastest to a rendered browser call?
Daily's prebuilt call object and embed components are the shortest path by design. LiveKit and Agora both ship prebuilt components too, but their product centers of gravity sit elsewhere: the self-hosted media plane and the managed global network respectively.
When should a team evaluate Devotel Orbit instead?
When the requirement is a customer-facing video surface rather than a media component: webinars with registrant sync, validated captions, PSTN and SIP bridging, and messaging on the same customer record. The AI video avatar agents post covers the agent lane, and the pairwise head-to-heads linked above disclose Orbit's position against each framework.
