Featured

Bring out the latest and greatest with our featured components.

WorkpoolWorkpools give critical tasks priority by organizing async operations into separate, customizable queues.

Cloudflare R2Store and serve files from Cloudflare R2.

Persistent Text StreamingStream text like AI chat to the browser in real-time while also efficiently storing it to the database.

Durable Functions

Long-running and resilient background task components.

CronsUse cronspec to run functions on a repeated schedule.

Workflow (Beta)Simplify programming long running code flows. Workflows can sleep for months, and wake up an perform the rest of your logic.

Action RetrierAdd reliability to an unreliable external service. Retry idempotent calls a set number of times.

Database

Components for real-time data management and synchronization.

Sharded CounterScalable counter that can increment and decrement with high throughput.

MigrationsFramework for long running data migrations of live data.

AggregateKeep track of sums and counts in a denormalized and scalable way.

Geospatial (Beta)Efficiently query points on a map within a selected region of the globe.

Integrations

Components for seamless third-party service integrations.

Cloudflare R2Store and serve files from Cloudflare R2.

Collaborative Text Editor SyncAdd a collaborative editor sync engine for the popular ProseMirror-based Tiptap and BlockNote rich text editors.

Expo Push NotificationsSend push notifications with Expo. Manage retries and batching.

Twilio SMSEasily send and receive SMS via Twilio. Easily query message status from your query function.

LaunchDarkly Feature FlagsSync your LaunchDarkly feature flags with your Convex backend for use in your Convex functions.

Backend

Essential backend infrastructure components.

Persistent Text StreamingStream text like AI chat to the browser in real-time while also efficiently storing it to the database.

Rate LimiterDefine and use application-layer rate limits. Type-safe, transactional, fair, safe, and configurable sharding to scale.

Action CacheCache action results, like expensive AI calls, with optional expiration times.

Frequently Asked Questions

How are components sandboxed?

The Convex runtime ensures that the component tables don't get mixed in with your app's tables. It also ensures that when the component runs its own Convex functions, they are not allowed to access your app's tables without explicit API calls.

What projects should use Components?

If you see a feature listed above, feel free to use it. The underlying component framework is still in beta, but we'll ensure that the components listed above stay up-to-date. Check each component's documentation for further guidance.

Can I build my own?

We'd love for you to build your own components to share and list on this page, and even make custom components specific to your project. We are still working on ironing out the authoring apis and will open that up soon.

Do components cost money to use?

Components are open source and are just code and data in your existing backend. They incur relevant usage charges based on how they are implemented and used.

Where can I learn more?

Visit the Components documentation to learn about how Components work, their data isolation model, and how they help you build features faster.
