The missing half of your React app

Convex is the open-source reactive database for web app developers.

What people building their business on Convex are saying

Convex allowed us to iterate very quickly on the models and schema by letting us see our changes deploy in real time. Convex allowed us to not think about the persistence layer, deduping of calls, loading states, pagination, or any part of the backend that you’re usually rolling yourself. The team was highly responsive and unblocked us when we needed it.

Convex has simplified our backend operations, allowing our team to focus on delivering value to our customers. Its reliable transactions help us develop complex features quickly and reliably, tightening our feedback loop. Convex really helps us put functionality and user experience first.

Read case study

Convex has re-imagined from the ground up what the primitives of an application platform should be, and are delivering on this vision with admirable rigor and comprehensiveness. Convex offers just about everything that a serious, modern software product might need to be successful, and the resulting DX is truly unparalleled!

These days, realtime collaboration and communication are table stakes, every product is expected to nail it. Convex makes it drop-dead simple to get the crazy-hard backend to make it happen, and I get to focus on making a magical user experience.

Next + Convex (all in typescript)

Vs

Angular (typescript) + Django (python) + Postgres + S3 + Websocket DIY + SQS + IaC + DIY e2e type safety

@convex_dev Simple. Fast. Realtime.

Robin@robinxpfp

I think @convex_dev might be the best DB I’ve ever used

Colin | Clerk.com@tweetsbycolin

Happy to see more first-class clerk x convex integration

There’s such a major architecture shift around Serverless + Edge + React + Typescript that (imo) it’s unlikely sql is still the right abstraction

Very compelling that convex is approaching this from first principles

Guillermo Rauch@rauchg

😱 @convex_dev is the gift that keeps on giving

Check it out in combination with @nextjs docs.convex.dev

@convex_dev is everything I wanted Firebase to be. Such a great tool. Feels illegal to know about this before others.

#dailytip if you are a #react developer and want an alternative to Firebase, you might want to give @convex_dev a try. It has amazing ReactHooks with samples in #Javascript and #typescript and the price isn't bad. I'm not a Firebase expert but it looks like all features are there

David Kim@dvddkkim

@convex_dev feels like what I wanted Firebase and MongoDB Realm to be and more. Really enjoying the DX so far!

James Perkins@james_r_perkins

I used @convex_dev once to make sure our integration at @ClerkDev worked and the docs matched what we expected.

It’s magical. I don’t say that lightly. I think it’s time to do a video on the channel.

Jason Lengstorf@jlengstorf

I’m working on a new app build with @convex_dev and I am *very* excited about the tech here

- DB schema defined in TS - end-to-end types (like if tRPC also set up your DB) - real-time updates Just Work™

Anshuman Bhardwaj@sun_anshuman

Managing an application's state has become easier, but the global state concept is still a pain for developers, which @convex_dev aims to solve. I made a realtime application using @convex_dev , @nextjs, and @auth0 and loved it.😍

Interesting tool of the week: convex.dev by @convex_dev

We like: Makes it easy to build a live-updating web app with a document database. Strictly-typed fully relational schemas defined in code (optional, but recommended)
