When Dyte became Cloudflare RealtimeKit, its customers did not choose a new provider. Their provider changed its name. Every package, every class prefix and every HTML tag in their code changed anyway, and the old SDKs went into maintenance mode, which in Dyte's own words means they "will no longer receive feature updates or bug fixes".
If a rename forces a rewrite, a real switch does more. This post is the inventory of what changes, layer by layer, taken from three migration guides the vendors wrote themselves. Whether to switch at all, and why providers exit, is covered in what happens when a video API provider is acquired or shuts down. This is about the work once you have decided.
Where video provider migration cost actually sits
The media itself is the easy part. Every provider moves WebRTC audio and video in broadly the same way. What you rewrite is everything your product built around one vendor's version of it:
Layer | What is provider-specific | Who notices if it goes wrong |
|---|---|---|
1. Object model | What a room, a participant and a track are called and how they relate | Your engineers, at compile time |
2. Auth | Token format and the server that mints it | Every user, at join time |
3. Events | Event names, and what each event actually means | Users, in subtle UI bugs |
4. Rendering limits | How many videos the SDK will draw, at what resolution | Product and sales |
5. Data you already hold | Recordings, IDs and history stored in the old provider's format and place | Compliance and support, months later |
Layer 1: the object model
Providers agree on the idea of rooms, tokens and tracks and disagree on almost everything else. Vonage calls the room a Session and gives clients publisher or subscriber roles. LiveKit has a Room, Participants and Tracks. Twilio has Rooms, Participants and Tracks too, but Zoom's Video SDK does not.
Zoom's own Twilio migration guide treats the move from Twilio's track-based model to Zoom's stream-based one as a fundamental architectural change, not a rename. There is no participant object; the current user comes from a function call. Code that loops over each video track to stop a camera becomes one call to stopVideo(). A single connect() becomes init() followed by join().
None of this is hard individually. The cost is that it is everywhere your product touches video, which is usually more places than anyone listed.
Layer 2: tokens and the server that mints them
Every provider needs your backend to issue credentials, and no two issue the same kind. Moving from Twilio to Zoom replaces Twilio's JWT with a Zoom JWT whose payload is different, and whose session-name claim has to match the session the client joins. Moving from Twilio to Amazon Kinesis Video Streams, in AWS's own guide, replaces the access token with temporary IAM credentials, Twilio's video grant with channel permissions, and the backend's room-creation endpoint with a signaling-channel endpoint.
So a provider switch is a backend change, not just a client one. Your token service, room creation, permissions model and any webhook handlers all move with it.
Layer 3: events, the part that breaks quietly
Event names change, and the mapping is rarely one to one:
Twilio Video event | Zoom Video SDK equivalent |
|---|---|
participantConnected | user-added |
participantDisconnected | user-removed |
trackSubscribed / trackUnsubscribed | peer-video-state-change |
dominantSpeakerChanged | active-speaker or video-active-change |
Renaming is the easy part. The risk is meaning. Zoom's guide notes that its speaker event fires when someone has been talking for more than a second, a rule worth checking against whatever your current provider does. A speaker-view layout tuned against one trigger can feel wrong against another, with no error anywhere. This is the layer where migrations pass every test and still generate support tickets.
Layer 4: rendering limits that change the product
Some differences are not code at all. The Zoom guide states that its web SDK "can render up to 25 videos at a time on desktop browsers, and 4 videos on mobile browsers", with 720p as the maximum rendering quality on web.
If your product shows a larger gallery, or relies on higher resolution, the migration is now a product decision. A provider's limits become your feature set, and sales finds out when a customer asks why the 30-person view disappeared.
Layer 5: the data you already hold
Code can be rewritten in a sprint. History cannot. By default, Twilio stores recordings in its own cloud; you can switch new recordings to your own S3 bucket, after which "Twilio will stop storing" them in its cloud, but recordings made before the switch stay where they were. Daily offers the same choice up front: with a custom bucket, it does not store the recording on its own servers at any point.
That one setting decides whether migration includes an archive project. Recordings, their metadata, the room and participant IDs your support and compliance teams reference: all of it has to be exported, re-linked and kept for as long as your retention policy says, in a format the new provider did not create. This is the part of what integrating a video SDK commits you to that arrives last and lasts longest.
Even a rename is a migration
Back to Dyte. Its RealtimeKit migration guide lists nine package replacements, from @dytesdk/web-core to @cloudflare/realtimekit and down through the UI kits, React Native, virtual background and recording SDKs. Class names lose the Dyte prefix for RealtimeKit or RTK; every dyte- HTML tag becomes rtk-.
This is the mildest migration there is: same team, same product, same concepts. It still touches every file that imports the SDK, and the maintenance-mode notice sets the deadline for you. That is the general shape of a forced move: the scope is yours, but the timeline is someone else's.
The honest counterweight
Not every migration is expensive, and not every one is necessary.
The work scales with how much of your product touches the SDK. A product that embeds a vendor's prebuilt meeting UI in one screen migrates in a fraction of the time of one that built custom layouts, moderation and recording workflows on raw tracks. And the reason to move can disappear: Twilio announced Programmable Video would end on 5 December 2024, extended that to December 2026, then on 21 October 2024 reversed the decision entirely. Teams that migrated early paid for a move that turned out to be optional.
The lesson is not "never depend on a provider". It is that the cost of leaving is decided long before you leave, by how far the provider's objects spread through your code.
Estimating your own video provider migration cost
- Count the touchpoints. Search the codebase for every import of the SDK and every provider type that crosses into your own state or UI.
- List the server endpoints. Token minting, room creation, webhooks, recording controls, analytics.
- Map every event you listen to, and write down what it means today, not just its name.
- Check the new provider's limits against your largest layout, highest resolution and platforms.
- Inventory the data: recordings, where they are, how long you must keep them, and how they are referenced.
The answer to each is your migration scope. If the first item returns hundreds of files, the problem is not the provider. It is that there is no seam between the provider and your product.
The Bottom Line
Moving video providers rarely rewrites the media. It rewrites the object model, the token service, the event handling and the UI limits your product was built around, and it leaves an archive of recordings in the old provider's place and format. Even a rename touches every import. The cost of leaving is set on the day you integrate, by how far the provider's objects reach into your code.
What's Next
This is the problem; the prevention is a seam. The Seam shows how to put video behind your own interface on day one, so the next switch is an adapter rather than a rewrite.
Frequently Asked Questions
What does it cost to migrate between video providers?
There is no public benchmark in time or money, because it depends on how much of your product touches the SDK. The work falls into five layers: the SDK object model, the token service, event handling, rendering limits, and the recordings and IDs you already hold. Counting your touchpoints in each is the most reliable estimate.
What has to be rewritten when switching video SDKs?
Client code that uses the provider's room, participant and track objects; the backend that issues tokens and creates rooms; every event handler; and any UI built around the provider's rendering limits. Zoom's Twilio migration guide, for example, lists nine separate changes for the web SDK alone.
What happens to my recordings if I change video providers?
They stay where the old provider stored them unless you move them. If recordings were written to the provider's cloud, migration includes exporting them and keeping them for your retention period. Writing recordings to your own storage from the start avoids this.
Is Twilio Video shutting down?
No. Twilio announced an end date for Programmable Video, extended it to December 2026, and on 21 October 2024 reversed the decision, saying Twilio Video will remain a standalone product.
How can I reduce video provider migration cost?
Keep the provider's objects behind an interface your product owns, issue tokens from one service, normalise events into your own vocabulary, and store recordings in your own bucket. Platforms that keep the media path, TURN and recording on infrastructure you control, such as Samvyo, which is based on SFU architecture, also keep the archive under your ownership rather than a provider's.
Does renaming an SDK count as a migration?
In practice, yes. Dyte's move to Cloudflare RealtimeKit replaced nine packages and renamed classes and HTML tags, and the old SDKs stopped receiving bug fixes, which sets the deadline for you.
