Kong vs Tyk vs Hasura — Best Open Source API Management Tools Compared

Every serious application eventually reaches the point where you need a layer between your clients and your services. That layer — call it an API gateway, API manager, or data API engine — handles routing, authentication, rate limiting, and analytics so your backend team does not have to. The commercial options are powerful but expensive, and they lock you into somebody else’s cloud. The good news is that three first-class open source platforms now cover this territory, and they approach it in quite different ways: Kong and Tyk are classic API gateways that sit in front of your services and manage traffic, while Hasura turns your database directly into a secure GraphQL and REST API. In this FOSS Face-Off I compare all three so you can pick the right foundation for your stack, all free and self-hosted.

1. Kong — The High-Performance Edge Gateway

Kong (by Kong Inc.) is the most widely adopted open source API gateway in the world. It is built on top of NGINX and OpenResty, licensed under the Apache License 2.0, and has gathered over 44,000 GitHub stars since it first appeared in 2014. If you want a battle-tested gateway that can sit in front of a swarm of microservices and swallow enormous traffic, Kong is the default.

The heart of Kong is proxying and routing: you declare services and routes, and Kong handles load balancing, health checks, and SSL termination in front of them. What makes it famous is the plugin system — there are dozens of built-in plugins for authentication (JWT, key auth, OAuth 2.0, basic auth), rate limiting, request and response transformation, CORS, logging, and much more, and you can write your own. Kong runs with a database for dynamic configuration or in a stateless DB-less mode driven by declarative config files, which fits a GitOps workflow. Recent versions have also positioned Kong as an AI gateway, routing and guarding LLM providers and MCP traffic.

• Ultra-high throughput — NGINX engine handles 50K+ transactions per second per node.
• Plugin platform — dozens of off-the-shelf auth, security, transformation and logging plugins.
• DB-less and hybrid modes — declarative config for GitOps, or a control plane/data plane split.
• Kubernetes native — the Kong Ingress Controller configures routing the same way you manage the cluster.
• Authentication library — JWT, key auth, OAuth 2.0, basic auth, and more out of the box.
• Rate limiting & traffic control — protect upstreams with granular consumer-based limits.
• AI/MCP gateway features — route across multiple LLM providers with security and observability.

Kong is the pick when raw performance, proven scale, and a mature plugin ecosystem matter more than a glossy admin dashboard. The core gateway is free; the enterprise dashboard, analytics and developer portal are paid add-ons, but the gateway itself is fully open under Apache 2.0.

2. Tyk — The Batteries-Included API Platform

Tyk (by Tyk Technologies) is a cloud-native API gateway written in Go, with its gateway core distributed under the Mozilla Public Licence 2.0. It has around 10,700 GitHub stars and markets itself as an “enterprise gateway that is open source” — the gateway ships batteries-included with no feature lockout. Where Kong leans on an NGINX foundation, Tyk is a purpose-built gateway that handles REST, GraphQL, TCP and gRPC traffic.

Tyk’s gateway is designed around explicit API definitions (including native OpenAPI 3.0 support) rather than proxy config files, which many teams find more intuitive. It gives you rate limiting and quotas per consumer, API versioning with scheduled deprecation, granular per-version access control, webhooks, and hitless reloads so configuration changes never drop a request. Analytics are a first-class citizen, with visibility into usage and performance. Extensibility comes through a middleware plugin architecture where you can write logic in JavaScript, Go, Python, or any gRPC-capable language.

• Written in Go — a lightweight gateway with no legacy proxy underneath and no third-party dependencies beyond Redis.
• Native OpenAPI 3.0 — keep your OpenAPI description as the source of truth for API definitions.
• Rate limiting & quotas — apply per-consumer and per-API limits to protect upstreams.
• API versioning — define and schedule deprecation of versions at specific dates.
• Granular access control — per-version and per-operation permissions, plus block/allow/ignore lists.
• Hitless reloads — change config and reload without interrupting active requests.
• Multi-language plugins — extend the middleware chain in JavaScript, Go, Python or any gRPC language.

Tyk is a strong middle ground: a genuinely open gateway core with built-in analytics, a mature API-definition workflow, and a full commercial platform (Dashboard, developer portal, self-managed management plane) when you outgrow the gateway alone. If you value an API-definition-centric workflow and multi-protocol support in a single lightweight binary, Tyk deserves a close look.

3. Hasura — Instant GraphQL APIs from Your Database

Hasura (by Hasura) is different from the other two. Rather than being a gateway in front of your services, it connects directly to your existing database — PostgreSQL and its flavours out of the box, plus MS SQL Server, and MongoDB, ClickHouse and more via the connector framework — and instantly generates a secure, high-performance GraphQL and REST API over your data. The engine is licensed under the Apache License 2.0 and has around 32,000 GitHub stars. It is the fastest way to expose a database to front-end applications without writing a single REST endpoint.

Point Hasura at a live database and you immediately get GraphQL queries with built-in filtering, pagination and search, plus mutations for inserts, updates and deletes. It adds realtime subscriptions — convert any GraphQL query into a live query so clients receive updates the moment data changes. Fine-grained access control lets you lock rows and columns down per role and user, integrating with your existing auth system. When you need custom business logic, Hasura lets you extend the schema with remote schema merging and Actions (your own REST endpoints), and it can trigger webhooks or serverless functions on database events, plus scheduled triggers on a cron schedule.

• Instant GraphQL + REST — a ready-to-use API over your database with no endpoint code.
• Realtime subscriptions — turn any query into a live query with push updates.
• Fine-grained access control — row- and column-level permissions tied to roles and your auth system.
• Merge remote schemas — bring your own custom GraphQL schemas into one endpoint.
• Actions — extend the generated schema with your own REST business logic.
• Database event triggers — fire webhooks or serverless functions on insert/update/delete.
• Scheduled triggers — run custom logic on a cron schedule or one-off.
• Admin console & migrations — a graphical console and Rails-inspired schema migrations.

Hasura is not a competitor to Kong and Tyk in the routing sense — it is a data-layer API engine. Choose it when your bottleneck is building APIs over a database and you want realtime, permissions and GraphQL almost for free.

Which One Should You Pick?

Choose Kong if: you need a battle-tested, ultra-high-throughput gateway in front of microservices, with a mature plugin ecosystem and Kubernetes-native operation. It is the safe, proven default for enterprise traffic at scale, and the core is fully Apache 2.0.

Choose Tyk if: you want a batteries-included API platform that treats API definitions, versioning and analytics as first-class citizens, with multi-protocol support (REST, GraphQL, TCP, gRPC) in a single Go binary. It is the best fit when you want an API-management workflow rather than raw proxy configuration.

Choose Hasura if: your priority is exposing an existing database as a secure GraphQL and REST API with realtime subscriptions and fine-grained access control, fast. It is not a replacement for a routing gateway — but used alongside one, it collapses weeks of backend API work into hours.

The Bottom Line

These three tools are not strict rivals — they solve adjacent problems, and many teams use a gateway and a data API engine together. Kong is the power player for edge traffic, Tyk is the complete API-management platform in a Go binary, and Hasura is the fastest route from a database to a secure, realtime GraphQL API. All three are genuinely free and open source (Apache 2.0 or MPL 2.0 core), all self-host cleanly, and all keep your infrastructure and your data under your own control.
