There is no universally verified ranking of the 20 most popular JavaScript backend frameworks. The shortlist below combines widely used Node.js frameworks with TypeScript tools, microservice platforms, API layers, and backend products that developers commonly evaluate together. Choose by service type, runtime, architecture, team experience, and measured workload—not by a popularity chart or a bare benchmark.
How to use this list
The State of JavaScript 2025 survey reports Express as the usage leader among the backend frameworks represented by its respondents, with NestJS progressing. That is survey context, not a universal market-share estimate. Respondents reported using an average of 1.9 backend frameworks, so most teams should narrow this list to one primary approach and perhaps a specialized companion.
These projects are not interchangeable. Express and Koa are small middleware-oriented cores; NestJS and AdonisJS provide stronger conventions; Moleculer focuses directly on microservices; Feathers emphasizes APIs and real-time applications; Strapi and Directus are backend data/content products; and tRPC is an API-layer choice rather than a complete HTTP server framework.

| Strapi | Headless content-management platform | Generated content APIs and editorial workflows | Not equivalent to a minimal general-purpose HTTP framework |
| Directus | API and data platform | Data-backed APIs over managed schemas | Evaluate it as a platform, not only as a routing library |
| tRPC | Type-safe API layer | End-to-end TypeScript applications | Usually paired with a server/runtime rather than used alone |
| Encore.ts | Opinionated TypeScript backend platform | Teams considering integrated backend tooling | Current adoption and detailed feature scope require project-specific verification |
| Meteor | Full-stack JavaScript platform | Products wanting an integrated full-stack model | Broader than a focused API or microservice framework |
1. Express: the flexible baseline
Express keeps the core small: routes, middleware and request/response handling, with the rest supplied by packages and your own architecture. That makes it a practical baseline for REST services, internal APIs and teams that want maximum freedom. The trade-off is that authentication, validation, error conventions, module boundaries and observability must be selected and maintained deliberately.
#1 Best Overall
2. NestJS: conventions and microservice transports
NestJS adds modules, dependency injection and application conventions while abstracting over Express or Fastify. Its dedicated microservices support and transport integrations make it a strong candidate when several teams need consistent boundaries and patterns. The same structure can feel heavy for a tiny endpoint, so decide whether the consistency benefit outweighs the abstraction.
3. Fastify: low overhead with measurable claims
Fastify’s official benchmark page, updated September 2, 2026, reports single-instance Node.js results of 97,595 requests per second and 9.73 ms latency for Fastify 5.12.1, versus 59,651 requests per second and 16.25 ms for Express 5.2.1. The page labels the comparison illustrative and notes that hardware, Node.js version and workload affect results. Those figures do not predict a database-backed production service. As the Fastify project puts it, “Machines matter, but so does the framework overhead.” Reproduce tests with your routes, middleware, payloads, database and deployment environment.
4. Hono: portability across runtimes
Hono provides a web-framework model with a Node.js adapter and documentation for running on Node.js. It is worth considering when the same service may move among Node, edge or serverless environments. Confirm that every middleware, runtime API and deployment target you need is supported before committing to portability as an architectural goal.

5. Koa: a minimalist middleware core
Koa belongs in the small-core, middleware-oriented group. It can suit experienced teams that want to compose their own stack, but a new project should verify current middleware maintenance, TypeScript ergonomics and operational tooling rather than assuming that a minimal core automatically means lower long-term cost.
6. hapi: plugin-oriented Node.js development
hapi is a Node.js framework with an official project site and a plugin approach. Compare its validation, routing, security and extension model directly with the current documentation. It appears in Fastify’s benchmark comparisons, but benchmark presence alone does not establish popularity or suitability for your service.
7. AdonisJS: integrated TypeScript backend
AdonisJS is backend-first and TypeScript-oriented, combining routing, middleware, validation and an ORM with conventions for common backend work. Its API-only mode can reduce unnecessary full-stack pieces while retaining structure. It is a reasonable choice when a team prefers integrated defaults over assembling an Express-style stack package by package.
Rank #2
8. Feathers: APIs with real-time patterns
Feathers targets API and real-time applications. Choose it when subscriptions, events or real-time adapters are first-class requirements rather than incidental additions. Check the current adapter set and ecosystem for the transports and data stores your service needs.
Do these 3 things before closing this tab:

LoopBack is a Node.js API framework for developers seeking more API-specific structure than a bare HTTP layer. Before selecting it for a long-lived platform, confirm the current release cadence, extension compatibility and maintenance details in the official project material.
10. Moleculer: architecture for microservices
Moleculer is a Node.js and TypeScript microservices framework, making it a direct architecture-focused alternative to NestJS. Evaluate its service discovery, transport, resilience and deployment model against your operational environment. If you only need one HTTP service, a smaller framework may be easier to operate.
11. Sails: MVC with API support
Sails is an established Node.js MVC/full-stack framework that can expose APIs. It is broader than a microservice-focused runtime. The cited current survey does not list it among the named primary backend items, so do not treat survey context as evidence of current popularity.
12. Restify: focused REST services
Restify is commonly considered for REST services and appears in Fastify’s benchmark table. Use that as a reason to measure it, not as proof that it is the best fit. Check its current plugins, TypeScript support, security posture and maintenance before adopting it for a new service.
13–15. Nitro, H3 and ElysiaJS
Nitro
Nitro is a server engine/framework in the broader JavaScript backend ecosystem and is listed in the State of JavaScript backend grouping. It is better evaluated as part of a broader deployment ecosystem than as a drop-in equivalent to Express.
H3
H3 sits in the Nitro/UnJS ecosystem and appears in Fastify’s comparison material. Confirm current runtime support and the relationship between H3 and your chosen deployment target in its documentation.
ElysiaJS
ElysiaJS is highlighted by the State of JavaScript survey as built on Bun. That runtime association matters: compare Bun compatibility, libraries and operations with the Node.js assumptions behind Express, NestJS and Fastify.
16–20. Platforms and API-layer choices
Strapi
Strapi is a content-management system that generates APIs. It is compelling when editorial workflows, content modeling and administration are central. It is not a minimal general-purpose HTTP framework for arbitrary microservices.
Directus
Directus is an API/data platform. Consider it when your primary problem is exposing and governing data over managed schemas, rather than writing every route and persistence layer yourself.
tRPC
tRPC provides a type-safe API approach for TypeScript applications. It improves contract sharing between a TypeScript client and server, but it is not a standalone server framework equivalent to Express or NestJS; pair it with an appropriate runtime and transport.
Encore.ts
Encore.ts is an opinionated TypeScript backend option. Because current popularity and detailed capabilities were not independently established here, evaluate its present documentation, deployment model and team fit before making it a platform standard.
Rank #4
Meteor
Meteor is a full-stack JavaScript platform with backend capabilities. It belongs on a broad technology shortlist, but teams seeking narrowly scoped APIs or independently deployable microservices should compare its full-stack assumptions with a focused framework.

Start with the service shape
- For a conventional REST API, shortlist Express, Fastify, NestJS, AdonisJS, Hono, Koa, hapi, LoopBack or Restify.
- For explicit microservice architecture, examine NestJS and Moleculer first, then verify the transports and operational features you require.
- For real-time applications, include Feathers and validate its current adapters.
- For content or data products, compare Strapi and Directus as platforms rather than routing libraries.
- For end-to-end TypeScript contracts, evaluate tRPC alongside the server framework it will use.
Match structure to team preference
Express and Koa leave more decisions to the team. NestJS and AdonisJS provide stronger conventions and integrated backend features. The right amount of structure is the amount your team will consistently follow and support.
Check runtime and deployment constraints
Confirm Node.js, Bun, edge and serverless requirements early. Hono documents a Node adapter, while ElysiaJS is associated with Bun. A framework that cannot run in the required environment is not a performance bargain.
Benchmark the application, not the logo
Use published microbenchmarks only to identify candidates. Build a representative test with authentication, validation, serialization, middleware, database calls, external requests, realistic payloads and your production hardware. Measure throughput, latency percentiles, memory, startup time and failure behavior.
Account for ownership cost
Compare documentation quality, dependency health, upgrade paths, observability, security updates, hiring familiarity and migration cost. Survey usage can provide ecosystem context, but it cannot decide whether your team can operate a framework successfully.
Common selection mistakes
- Calling this shortlist a definitive popularity ranking.
- Choosing a framework from a bare “requests per second” number.
- Treating a CMS or data platform as equivalent to a low-level HTTP framework.
- Ignoring runtime constraints until deployment.
- Adopting a microservice framework before confirming that separate services are operationally justified.

Frequently Asked Questions
Is Express still a sensible choice for a new API?
Yes, when your team wants a small core and is prepared to choose its own validation, authentication, error handling and observability stack. Usage leadership in the 2025 survey is context, not a guarantee of fit.
Should I choose NestJS or Fastify for a microservice?
Choose NestJS when shared modules, dependency injection and transport conventions are priorities. Choose Fastify when a low-overhead HTTP core is more important and your team will supply the surrounding architecture.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
Does a higher benchmark score prove a framework is faster in production?
No. The published Fastify comparison is a single-instance illustration. Database access, middleware, payload size, external calls, hardware and Node.js version can change the result.
Can tRPC replace Express or NestJS?
Not by itself. tRPC is an API-layer and type-contract approach that normally runs with a server framework or runtime.
The Bottom Line
Shortlist by architecture first: Express or Koa for minimal composition, NestJS or AdonisJS for conventions, Fastify for a low-overhead Node.js core, Moleculer for explicit microservices, Feathers for real-time APIs, and Strapi or Directus for content/data platforms. Validate runtime compatibility and benchmark your real workload before committing.
