Convex + Next.js
BeginnerWeb AppNext.js with a real-time, authenticated Convex backend: type-safe, subscription-first full-stack.
Published 27 September 2026
About Convex + Next.js
Convex + Next.js replaces the traditional database + ORM + API layer with a single reactive backend platform. Convex is a TypeScript-native backend-as-a-service that stores data in a document database, auto-generates type-safe query functions, and pushes live updates to subscribed clients without polling. Next.js handles the frontend with React components, and Convex integrates as a client-side subscription layer that keeps your UI in sync with server state automatically.
The most distinctive feature of Convex is that queries and mutations are written as ordinary TypeScript functions deployed to Convex's cloud, not SQL, not ORM methods, not REST routes. You call them from React components with useQuery and useMutation hooks. When data changes on the server, every subscribed component re-renders with the new value within milliseconds. Real-time collaborative apps, live dashboards, and multi-user tools that would normally require WebSocket infrastructure come almost for free.
TypeScript types flow from your Convex schema through to your React components with no manual code generation step: change a field name in the schema and the compiler tells you everywhere the UI breaks. Next.js deploys to the usual serverless platforms with little configuration. This stack is beginner-friendly in the sense that there is very little glue code to write, but Convex's reactive model requires a mental shift away from request/response thinking.
Key Features
- ✓Convex queries and mutations written in TypeScript: no SQL, no ORM, no REST boilerplate
- ✓Real-time subscriptions push data changes to all connected clients automatically
- ✓End-to-end TypeScript types from Convex schema to React component, with no manual code generation step
- ✓Next.js App Router for SSR, routing, and layouts on Vercel
- ✓Convex handles auth, file storage, scheduled functions, and background jobs built-in
- ✓Zero-config deployment: Convex functions deploy via CLI, Next.js deploys via Vercel
When to Use Convex + Next.js
- →Real-time collaborative tools (shared docs, whiteboards, live cursors)
- →Multi-user apps where all clients need to see the same live state
- →Chat apps and notification feeds without a custom WebSocket server
- →MVPs where the team wants full-stack TypeScript with minimal infrastructure decisions
- →Dashboards that show live data without manual refresh
Pros
- Real-time by default: no polling, no WebSockets to manage, no stale data
- End-to-end TypeScript eliminates an entire class of frontend/backend contract bugs
- Convex built-in scheduler, file storage, and auth reduce the number of third-party services needed
- Very little glue code, since query functions replace controllers, ORMs, and migration files
Cons
- Convex's query and function model has no drop-in equivalent elsewhere, so the app depends on Convex even though its backend can be self-hosted
- Document database model lacks SQL joins; complex relational queries require denormalisation
- Reactive model requires a different mental model than REST, a steeper conceptual learning curve than it appears
- Convex pricing can become significant for high-throughput write workloads
Authentication Options for Convex + Next.js
Convex + Next.js with Convex Auth
Convex's own first-party authentication library: OAuth, email, and password sign-in with sessions stored directly in your Convex tables, so auth data lives in the same reactive database as the rest of the app instead of a separate provider.
Convex + Next.js with Clerk
A managed auth platform with prebuilt sign-in/sign-up UI and social logins, wired into Convex via its official JWT integration. The pick if you want Clerk's hosted dashboard and UI components rather than owning the auth flow the way Convex Auth's in-table sessions do.
These are highlighted picks. To see all the tools, check the Authentication category.
Hosting Options for Convex + Next.js
Deploy Convex + Next.js on Vercel
The platform Next.js's own team builds for. Zero-config deploys straight from a git push, with automatic preview environments for every PR and edge/serverless functions handled for you. Deploy automation comes bundled, so a separate CI/CD tool isn't required just to redeploy on a push to the main branch; a CI/CD addition still earns its place here for running a test suite or lint checks that gate the deploy, rather than for the deploy mechanism itself.
Deploy Convex + Next.js on Netlify
A comparable git-based deploy platform to Vercel, with strong SSR/static build support, a mature build-plugin ecosystem, and split-testing features. Like Vercel, it redeploys automatically on push with no CI/CD tool required just to ship. A CI/CD addition adds the most value here for running tests before that deploy goes out, not for the deploy step itself.
Deploy Convex + Next.js on Firebase Hosting
Google's static hosting layer, typically paired with Cloud Functions for any server-rendered routes. It lacks Vercel/Netlify's all-in-one framework adapters, so setup takes more manual configuration. Makes the most sense if the rest of the project already lives in the Firebase/GCP ecosystem rather than as a standalone pick. Deploys go through the Firebase CLI, not an automatic git-push pipeline by default, so a CI/CD tool has a more literal job here than on Vercel or Netlify.
Deploy Convex + Next.js on Railway
A container-based platform where the app deploys as a persistent service instead of a set of serverless functions, useful if it needs long-running processes, WebSocket connections, or background jobs that a serverless function model does not fit well. Railway also auto-deploys from a connected repo on push, so a CI/CD addition here is again mainly about pre-deploy testing rather than the deploy step.
Deploy Convex + Next.js on Render
A similar persistent-service model to Railway, with built-in cron jobs and a genuinely free tier for small projects: a straightforward alternative if predictable pricing matters more than usage-based serverless billing. Deploys automatically on push the same way Railway and the serverless platforms do, so CI/CD's value here is pre-deploy testing, not the deploy itself.
These are highlighted picks. To see all the tools, check the Hosting & Cloud category.
Convex + Next.js Add-ons
Each addition below extends this stack with a capability the base stack works fine without. None are required: include the ones your product actually needs when building this stack, and skip the rest.
CI/CD Add-ons
Add CI/CD when you want a dedicated pipeline for running tests, linting, or multi-stage builds before a deploy goes out. Many hosting platforms already redeploy automatically on every push on their own — a CI/CD tool adds the most value on top of that by gating the deploy on a passing test suite, and matters even more when the hosting choice does not auto-deploy at all, such as a self-hosted server.
Convex + Next.js with GitHub Actions
Runs the test suite and triggers deployments on every push, directly from the same GitHub repo the code already lives in, with no separate CI service to configure.
Convex + Next.js with GitLab CI/CD
GitLab's built-in CI/CD system, configured via .gitlab-ci.yml in the repository, the natural pick if the project's code lives on GitLab (self-hosted or gitlab.com) rather than GitHub, with the same YAML-pipeline model as GitHub Actions.
These are highlighted picks. To see all the tools, check the CI/CD Pipelines category.
Containerization Add-ons
Add containerization when you want the app packaged the same way across local development, staging, and production, or need to deploy somewhere that isn't a managed serverless platform.
Convex + Next.js with Docker
Packages the app and its dependencies into a container image for consistent local development and deployment, independent of the hosting platform chosen above.
These are highlighted picks. To see all the tools, check the Containerization category.
Email Add-ons
Add email when the app needs to send account verification, password reset, or notification messages.
Convex + Next.js with Resend
A transactional email API for account verification, password resets, and notification emails, the kind of email a SaaS app sends on behalf of the system rather than a marketing campaign. Drops into Next.js Server Actions or Route Handlers with a few lines of code, with a free tier for getting started.
Convex + Next.js with SendGrid
The established high-volume choice, with dedicated IP addresses and deliverability tooling for apps sending at serious scale. There is no permanent free plan (a 60-day trial, then paid tiers), so it earns its slot when volume and deliverability matter more than upfront cost.
Convex + Next.js with Brevo
An all-in-one platform that combines the transactional email API with marketing campaigns, a built-in CRM, and SMS from the same dashboard. Its permanent free tier of 300 emails a day with no card required makes it an easy starting pick for early-stage apps that will also want lightweight marketing sends.
Payments Add-ons
Add payments when the product is ready to charge for subscriptions or one-time purchases.
Convex + Next.js with Stripe
Adds subscription billing, one-time checkout, and invoicing via Stripe's hosted Checkout or embedded Elements. The stack works fully without it; add this once the product is ready to charge for something.
Styling Add-ons
Add styling when you want a component or utility-class system to build the UI faster than hand-writing CSS from scratch.
Convex + Next.js with Tailwind CSS
A utility-class CSS framework: styles are composed directly in markup via class names instead of writing separate stylesheet files. The default styling choice bundled by most modern framework CLIs (create-next-app, create-vue, the SvelteKit and Astro starters all offer it), and the base layer shadcn/ui components are built on when that's loaded into the catalog in the future.
These are highlighted picks. To see all the tools, check the CSS Frameworks category.
Analytics Add-ons
Add analytics when you want to measure traffic, track visitor behavior, or understand how people actually use the product.
Convex + Next.js with PostHog
An all-in-one product analytics platform: event tracking, session replay, feature flags, and A/B testing in one SDK. The richest feature set if you want more than pageviews.
Convex + Next.js with Google Analytics
The industry-standard, free analytics platform, with native Google Ads and Search Console integration. Requires a cookie consent banner in most jurisdictions (GDPR/CCPA), and all data lives on Google's infrastructure, the tradeoff the other three picks were built to avoid.
Convex + Next.js with Plausible Analytics
A lightweight, privacy-first analytics tool with no cookie banner required. A good fit for simple traffic metrics without PostHog's broader feature surface.
Convex + Next.js with Umami
Open-source and self-hostable, keeping analytics data on infrastructure you control. The natural pick if you want to avoid a third-party analytics vendor entirely.
These are highlighted picks. To see all the tools, check the Web & Product Analytics category.
Frequently Asked Questions about Convex + Next.js
Should I use Convex Auth or Clerk?
Convex Auth is the default because it needs no separate account or SDK beyond what Convex already provides. Clerk is worth adding if you want more polished, pre-built sign-in UI or need Clerk's specific enterprise features. It has an official, documented Convex integration via a JWT template, not just a generic pairing.
How is this different from Convex + React?
Same Convex backend, same auth options. The difference is entirely architectural: this stack adds Next.js's App Router with server-side rendering and Server Components on top of Convex's client-side subscriptions, while Convex + React is a pure client-side SPA with no server-rendering layer at all. Pick this one if the project needs SEO or server-rendered pages; pick the React version for the simplest possible setup when neither matters.
Can I migrate away from Convex later?
Convex is the most tightly-coupled backend in this catalog. Its query language, function runtime, and real-time subscriptions have no drop-in equivalent elsewhere, so migrating away means rewriting the backend from scratch, not swapping a client library or connection string.
What's the cheapest way to run this stack?
Convex's free Hobby tier covers a generous amount of function calls, storage, and bandwidth for a small app at zero cost. Vercel's free Hobby tier covers the Next.js frontend at the same scale, so a small project can run this entire stack without a hosting bill until real traffic shows up.

Scores
Popularity2/5
Convex is a newer entrant compared to Firebase or Supabase, with a smaller community and fewer production case studies for a full Next.js integration specifically. It is genuinely capable, but not yet a mainstream default backend for Next.js apps the way Supabase or a traditional database already is.
Learning Curve3/5
Next.js developers already know React and file-based routing, so the frontend half is familiar. What takes adjustment is Convex's function-based backend model: queries and mutations replace API routes and ORM calls, and pairing that with Next.js's own App Router and Server Components adds a second mental model to hold at once.
Flexibility2/5
Convex is an opinionated, all-in-one backend with its own query language, function runtime, and real-time subscription model, layered underneath Next.js's own opinionated App Router. Between the two, there is little room to swap in a different database or backend pattern without leaving Convex behind entirely, or a different frontend pattern without leaving Next.js's conventions behind.
Performance4/5
Convex pushes data updates to subscribed components automatically without polling, and a Vercel deployment adds edge caching and fast static asset delivery on top. Not a 5 only because Convex's function cold starts add latency a warmer, always-on runtime would not have, and mixing Convex's client-side subscriptions with Next.js's server-rendered pages needs care to avoid hydration mismatches.
Portability1/5
Convex is the most locked-in backend in this catalog. Its query language, function runtime, and real-time model have no equivalent elsewhere, so migrating away means rewriting the entire backend, not just swapping a client library, regardless of which frontend framework sits on top of it.
