How to switch from Stream to Twilio

Full Stream export guide →

1Export your existing data from Stream using the Export Channels API - trigger the async export job per channel or in batches, then download the resulting JSON files from the signed S3 URLs before deleting anything.
2Map your Stream data model (channels, messages, members) to Twilio Conversations' model (conversations, messages, participants) and write a migration script to import via the Conversations API.
3Rebuild your chat UI from scratch or with a third-party library, since Twilio doesn't ship the same pre-built React/Flutter/iOS/Android components Stream provides.
4Recreate moderation rules and webhooks - set up Twilio's Conversations webhooks and add a third-party moderation service if you relied on Stream's built-in AI moderation.
5Replace any activity feed functionality separately, since Twilio has no feed product; either keep a lightweight feed service or build custom ranking logic.
6Run both systems in parallel for a test group, validate message delivery and history are intact, then cut over the rest of the team and decommission the Stream app/API keys.

Stream vs Twilio: common questions

How do I export my chat data out of Stream before switching?+

Stream doesn't have a one-click 'download everything' button. You export data by calling Stream's Export Channels API, which queues an async job and returns a downloadable JSON file (via a signed S3 URL) containing channels, messages, and members. For large accounts you'll need to paginate through channel lists and trigger export jobs in batches.

What features do I lose if I move from Stream to Twilio?+

You lose Stream's pre-built chat UI kits (React, Flutter, iOS, Android) and its ranked activity feed engine - Twilio's Conversations API is lower-level and requires you to build your own UI. Built-in AI moderation is also weaker on Twilio, so you'll likely need a third-party moderation add-on.

Is Twilio's free trial enough for a small team's real usage?+

No - Twilio's trial only gives you a small amount of credit (typically around $15) meant for testing, not production traffic. Once you go live you're billed per SMS, minute, or participant-minute from day one, unlike Stream's ongoing 25 MAU free tier.

Will my existing integrations still work after switching to Twilio?+

Webhooks, moderation hooks, and push notification configs tied to Stream's chat events won't carry over and need to be rebuilt against Twilio's Conversations webhooks. If you were using Stream's activity feeds for social features, there's no direct Twilio equivalent, so that logic has to be replaced or built separately.

Does switching to Twilio actually cost more over time than staying on Stream?+

It depends on usage mix: if you only need chat and stay under 25 MAU, Stream stays free while any Twilio usage is billed immediately. But if you need SMS, voice, or video alongside chat, Twilio's usage-based pricing can end up cheaper than paying for Stream's paid chat tier plus separate SMS/voice vendors.
