Kong vs AWS API Gateway
This is a platform against a building block. Kong is an open-source gateway with a managed control plane, a developer portal and an AI gateway, built for platform teams. AWS API Gateway is a pay-per-call cloud service tied closely to Lambda, with no developer portal worth the name. Partner-facing API programmes choose Kong; small AWS teams choose AWS.
Vendors can pay for visibility on this site; it never changes what we say about a product. How that works.
Choose Kong ifyou need a developer portal and governance across many APIs, already run Kubernetes with a platform team, and want an open-source gateway you can host yourself.
Choose AWS API Gateway ifyou are already on AWS, mainly exposing Lambda functions or backend services, and want to pay only for the calls you receive without running a gateway yourself.

Where they differ
Kong 1 · AWS API Gateway 2 · open 1- 01
A portal for outside developers
Kong Konnect includes a developer portal on top of the gateway. AWS API Gateway is strong at routing and metering but has no built-in developer portal or API catalogue worth the name, so companies needing self-service end up bolting something on or moving away. For APIs offered to partners or the public, Kong is the complete product.

Cost at small or uneven volume
AWS charges per API call and data transfer at published rates, with a free tier for new accounts; for a handful of Lambda functions nothing is cheaper. Kong's gateway is free to self-host, but Konnect's per-gateway and per-million-request pricing is hard to forecast past the entry plan. For low or spiky traffic, AWS is the simpler bill.

Who has to operate it
AWS API Gateway is a managed cloud service you rent, which suits a startup or a single team testing an idea. Kong rewards an organisation that already has a platform team; it is explicitly a poor fit for a small team without a platform engineer that needs one API published this week. On operational load, AWS asks less.

Tied to one cloud or not
AWS API Gateway's appeal rests on deep AWS and Lambda integration, and its value is conditional on already being on AWS. Kong's open-source gateway is self-hosted on infrastructure you choose, typically Kubernetes. A committed AWS shop loses nothing by the tie-in; an organisation spread over several environments gains from Kong's independence.
Depends on the buyer
When neither fits
A team that wants a managed gateway with a portal, but a bill that does not move with every request, sits between the two. Tyk's Professional plan is flat-rate with unlimited requests, and Gravitee charges a flat monthly fee per gateway with a portal included.
Kong or AWS API Gateway: questions
3 answersDoes AWS API Gateway have a developer portal like Kong?
Not a built-in one worth the name. AWS API Gateway routes and meters traffic well but leaves the self-service catalogue to you. Kong Konnect includes a developer portal, which is why companies needing partner-facing APIs often move from AWS to Kong or a similar platform.
Is AWS API Gateway cheaper than Kong?
For a small number of APIs on AWS, yes: pay-per-call pricing with a free tier is hard to beat.
Kong's open-source gateway is free but must be run by someone, and Konnect's pricing is harder to forecast. At large steady volume, model both against your traffic.
Can I start on AWS API Gateway and move to Kong later?
That is a path our data describes: companies that outgrow AWS API Gateway's lack of governance, monetisation or a portal end up adding tools on top or moving to a platform such as Kong.
How hard the migration is depends on your setup and is not covered.
