What tech stack do Netflix, Uber and Airbnb use?
Netflix, Uber, and Airbnb solve different engineering problems with overlapping tools. Explore their publicly documented stacks and learn which architectural choices are worth adapting to your own product.
Three technology stacks built for three different problems
The question what tech stack do netflix, uber and airbnb use? is useful only if you look beyond a list of programming languages. Netflix delivers streaming entertainment, Uber coordinates real-time physical marketplaces, and Airbnb manages a global travel marketplace. Their technology choices reflect those workloads, along with years of organizational growth and infrastructure investment.
This MyDiscussions guide compares their publicly documented architectures, explains the trade-offs, and provides a practical process for choosing your own stack. These are representative technologies, not exhaustive inventories or guarantees of current usage. Large companies migrate systems gradually, and engineering articles often describe a particular team or period rather than the entire organization.
Netflix, Uber, and Airbnb tech stacks at a glance
All three companies use multiple languages, distributed services, extensive data infrastructure, and custom developer tooling. But their most important architectural differences are about traffic patterns and correctness—not whether they use React.
| Layer | Netflix | Uber | Airbnb |
|---|---|---|---|
| Primary product workload | Streaming, discovery, personalization | Dispatch, location updates, trip coordination | Search, availability, booking, payments |
| Client technologies | React for web experiences; native and device-specific clients | Native mobile apps; React-based web tooling | React web applications; native mobile apps |
| Backend languages | Java, Kotlin, Python, Node.js in different contexts | Go, Java, Python, and legacy Node.js systems | Ruby, Java, Kotlin, and other service-specific languages |
| Representative storage | Cassandra, MySQL, EVCache | MySQL-derived storage systems, Redis, specialized distributed storage | MySQL, Redis, Elasticsearch-based search systems |
| Events and analytics | Kafka, Flink, Spark | Kafka, Flink, Spark | Kafka, Spark, Airflow |
| Infrastructure direction | AWS for substantial compute and platform infrastructure; Open Connect for video delivery | Hybrid infrastructure with major Google Cloud and Oracle Cloud partnerships | AWS-based infrastructure and Kubernetes-backed service platforms |
| Architectural emphasis | Playback reliability and efficient content delivery | Low-latency coordination and geographic distribution | Transactional correctness and marketplace development speed |
Do not read a shared technology as a shared implementation. Kafka may move operational events, analytics records, or change-data-capture streams. MySQL can sit behind a straightforward application or a heavily customized storage platform.
What tech stack does Netflix use?
Separate the streaming platform from video delivery
Netflix’s most important architectural distinction is between application infrastructure and media distribution.
Its application systems handle functions such as authentication, discovery, recommendations, and playback coordination. AWS supports substantial portions of this infrastructure.
The video bytes themselves are delivered through Open Connect, Netflix’s purpose-built content delivery network. Open Connect appliances are deployed within or close to internet service provider networks, reducing the distance between content and viewers.
The official Netflix Open Connect overview explains this delivery model. The practical lesson is that the control path and the high-volume data path do not have to use the same infrastructure.
For an ordinary video product, managed video processing and a commercial CDN are usually more sensible than building an appliance-based distribution network.
Backend services, APIs, and user interfaces
Netflix is strongly associated with Java and JVM-based services, alongside Python for data and automation and Node.js in selected application and interface layers.
React has been used for web interfaces, but “Netflix uses React” does not describe its television, mobile, browser, and embedded-device clients. Those environments have different memory limits, rendering systems, and release processes.
Netflix has also publicly described GraphQL federation and its DGS framework, a JVM framework for GraphQL services. This approach lets domain teams contribute to a shared API while owning the services behind it.
The trade-off is coordination overhead. Federation can simplify client access, but it introduces schema governance, query-performance concerns, and cross-service failure modes.
Storage, caching, and data processing
Representative Netflix technologies include:
- Apache Cassandra for distributed storage workloads.
- MySQL for workloads suited to relational storage.
- EVCache, Netflix’s distributed caching system built around Memcached.
- Apache Kafka for event transport.
- Apache Flink and Apache Spark for stream and batch processing.
- Amazon S3 for object storage and data-platform workloads.
These tools solve different problems. Cassandra favors distributed availability and scalable access patterns; it is not a drop-in replacement for relational joins and multi-row transactions. EVCache reduces repeated computation and storage reads, but cache invalidation and fallback behavior become part of application correctness.
Netflix’s resilience engineering is equally important. Timeouts, isolation, controlled failure testing, and graceful degradation help keep a slow dependency from disrupting the wider experience.
The transferable lesson: design recommendations and other optional features so their failure does not unnecessarily block a core user journey.
What tech stack does Uber use?
A real-time marketplace rather than a map application
Uber’s backend must coordinate changing locations, driver availability, prices, dispatch decisions, trip state, and payments. These operations have different latency and consistency requirements.
An approximate vehicle position may be acceptable on a map. An ambiguous payment or conflicting trip assignment is a different class of failure.
Uber has publicly documented extensive use of Go and Java, with Python supporting data and other workloads and Node.js appearing in its earlier architecture. It moved from early application structures toward a large service ecosystem as its product and organization expanded.
The critical lesson is not to adopt Go because Uber uses it. It is to separate workload requirements before selecting service boundaries and implementation languages.
Mobile clients and service communication
Uber’s rider and driver experiences depend heavily on native mobile capabilities: location services, notifications, background execution, and platform-specific interfaces.
Uber has published RIBs, a cross-platform architectural framework with implementations for Android and iOS. RIBs organizes application logic and lifecycle management; it does not mean every screen is rendered by one shared cross-platform UI runtime.
On the backend, Uber has documented RPC-oriented infrastructure and technologies including gRPC. Typed contracts help large teams evolve service interfaces, but they do not eliminate compatibility problems.
Any team adopting this model still needs rules for:
- Request deadlines and cancellation.
- Retries and idempotency.
- Backward-compatible schema changes.
- Authentication and authorization between services.
- Distributed tracing and dependency ownership.
Storage, event streaming, and analytics
Uber has published engineering work around MySQL-backed Schemaless, Docstore, Kafka, Flink, Spark, and large analytical platforms. These systems illustrate how storage evolves when a company needs specialized access patterns, scale, and operational controls.
They should not be collapsed into the claim that “Uber’s database is MySQL.” A storage service layered over MySQL may expose very different partitioning, replication, and consistency behavior from a conventional application database.
Uber has also used H3, its hierarchical hexagonal geospatial indexing system. H3 helps group geographic space into cells for analysis and location-related computation. It does not replace routing, traffic estimation, or road-network data.
Uber’s official engineering publication is useful for examining these systems in their original context.
Infrastructure and operational trade-offs
Uber has operated substantial private infrastructure and announced major cloud partnerships with Google Cloud and Oracle Cloud. Describing it as exclusively on one cloud misses that evolution.
Hybrid infrastructure can support migration flexibility and workload placement, but it adds networking, identity, deployment, and observability complexity.
The transferable lesson: invest early in explicit state transitions, idempotent operations, and location-aware modeling. Delay custom storage platforms and multi-environment infrastructure until a measured limitation justifies them.
What tech stack does Airbnb use?
From Ruby on Rails toward a service-oriented platform
Airbnb is closely associated with Ruby on Rails, which supported its early marketplace development. Rails remains relevant to understanding its engineering history, but it is misleading to describe Airbnb as only a Rails monolith.
Airbnb has documented a transition toward service-oriented architecture, including Java and JVM-based services, as teams and product domains expanded.
Rails offers strong conventions for building database-backed workflows quickly. Services can enable independent deployment and clearer domain ownership, but they introduce network failures and make cross-domain transactions harder.
For a smaller marketplace, a well-structured Rails application may provide more value than an early service mesh. The relevant question is whether teams actually need independent releases and scaling—not whether a monolith appears less sophisticated.
React on the web and native mobile development
Airbnb is a prominent React user for web development and has published substantial work on frontend infrastructure and design systems.
Its mobile history needs careful treatment. Airbnb adopted React Native and later publicly explained its decision to move away from it. Therefore, listing React Native as Airbnb’s general current mobile stack based on older stack directories is unreliable.
Airbnb’s official React Native retrospective discusses integration, tooling, and organizational challenges behind that decision.
This does not prove React Native is unsuitable for other companies. It demonstrates that shared application code can still require significant platform-specific expertise, especially when integrated into large existing native applications.
Booking storage, search, and data infrastructure
Airbnb has publicly discussed technologies including:
- MySQL for relational data.
- Redis for caching and supporting workloads.
- Elasticsearch-based systems for search.
- Kafka for event-driven data movement.
- Spark for data processing.
- Airflow, which originated at Airbnb, for workflow orchestration.
- AWS and Kubernetes for infrastructure and service-platform workloads.
A marketplace must distinguish between search discovery and booking authority. A search index can tolerate some delay in reflecting listing changes. The operation that confirms a reservation must enforce the relevant availability and booking rules against authoritative state.
Airflow also deserves a precise label: it schedules and coordinates workflows. It is not itself a database, streaming broker, or general-purpose distributed compute engine.
The transferable lesson: use specialized read systems for discovery while protecting booking and payment invariants in authoritative transactional workflows.
How to choose a stack using these companies as references
Step 1: Identify the business operation that cannot fail incorrectly
Choose a core invariant before choosing a framework:
- Streaming: authorized users should reliably start and continue playback.
- Ride-hailing: trip assignments and lifecycle transitions must remain valid.
- Booking: reservations must obey availability and payment rules.
Distinguish an unavailable optional feature from an incorrect financial or inventory action.
Step 2: Define measurable workload requirements
Record expected peak concurrency, request latency targets, data volume, geographic coverage, and acceptable data staleness.
Include operational criteria:
- Recovery time and acceptable data loss.
- Security, privacy, and retention requirements.
- On-call staffing and incident-response capability.
- Deployment frequency and release independence.
- Infrastructure budget, including network egress.
A database that performs well in isolation may still be unsuitable if the team cannot restore it reliably.
Step 3: Choose the smallest viable architecture
For an early product, a reasonable starting point might be a modular Rails, Spring Boot, Django, or Node.js application with PostgreSQL or MySQL.
Add object storage and a CDN for media. Introduce background jobs where work can leave the request path. Add Redis or a search engine when specific access patterns justify them.
This is not a miniature Netflix stack. It is a simpler architecture that can preserve similar boundaries without inheriting the same operational burden.
Step 4: Select tools against explicit trade-offs
| Decision | Favor the simpler option when | Consider added infrastructure when |
|---|---|---|
| Monolith vs. services | One team owns most releases | Domains need independent ownership and deployment |
| Relational DB vs. distributed storage | Transactions and flexible queries dominate | Proven capacity or geographic requirements exceed the existing design |
| Job queue vs. Kafka | Work needs asynchronous execution | Multiple consumers need durable, replayable event streams |
| Database search vs. search engine | Filtering and text retrieval remain basic | Ranking, faceting, or retrieval requirements become specialized |
| Managed platform vs. Kubernetes | Operational staffing is limited | Platform requirements justify cluster and tooling ownership |
Step 5: Validate failure behavior and total cost
Prototype difficult paths, not just successful requests. Test duplicate events, dependency timeouts, cache loss, delayed search updates, and failed payment callbacks.
Estimate costs across compute, storage, replication, observability, support, and engineering time. Managed services may have higher visible bills while lowering the staffing needed to operate them.
Step 6: Set migration triggers
Write down what would justify the next architectural step: sustained database pressure, release contention, unacceptable recovery time, or a regulatory requirement.
Migrations are safer when driven by evidence rather than prestige. For adjacent comparisons, browse more Tech stack topics.
Common mistakes when copying these stacks
- Treating historical tools as current defaults. Netflix-origin projects such as Hystrix and Zuul need lifecycle checks before adoption; company association is not a maintenance guarantee.
- Copying microservices without ownership boundaries. Network separation alone produces a distributed monolith.
- Using one consistency model everywhere. Search results, map positions, bookings, and payments have different correctness needs.
- Ignoring the delivery layer. Netflix’s CDN architecture matters more to video economics than its frontend framework.
- Building bespoke platforms too early. Custom storage and deployment systems require dedicated maintainers.
- Equating shared code with lower total cost. Cross-platform development can shift work into integration and debugging rather than remove it.
Frequently asked questions
Do Netflix, Uber, and Airbnb use the same tech stack?
No. They share technologies such as React, Kafka, Spark, and JVM languages, but combine them differently. Their architectures reflect streaming delivery, real-time transportation, and travel booking requirements.
Does Netflix run entirely on AWS?
No. AWS supports substantial application and platform infrastructure, while Netflix’s Open Connect network delivers video content. Client devices and other external systems also participate in the complete service.
Is Airbnb still a Ruby on Rails application?
Rails is central to Airbnb’s history, but its publicly documented architecture includes services beyond that original application. “Airbnb uses Rails” is useful context, not a complete description of its backend.
Which company’s stack should a startup copy?
Copy none wholesale. Adopt the relevant principles: Netflix’s separation of media delivery, Uber’s explicit real-time state management, or Airbnb’s separation of discovery from booking correctness. Choose tools your team can operate, then expand the architecture when evidence supports it.
