The short version

Only Kong has a free tier, so it costs nothing to try first.
Each has a real cost: Kong the Plus plan includes 1M API requests a month and charges $200 a month for each additional million; Zuora pricing includes a component tied to the volume you bill, so the fee rises with your own commercial success in a way a flat platform charge does not, and the renewal conversation after a strong year is a different negotiation from the original one.
They diverge on capability: Kong covers API Gateway, Zuora covers Product catalogue.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Kong

The Plus plan includes 1M API requests a month and charges $200 a month for each additional million
Plus is capped at 10M requests a month, so growth past that forces an Enterprise contract
Plus limits published APIs to 20 and includes one Developer Portal, with a second at $200 a month
SSO and audit logging are Enterprise only
Enterprise pricing is custom and billed annually

Zuora

Pricing includes a component tied to the volume you bill, so the fee rises with your own commercial success in a way a flat platform charge does not, and the renewal conversation after a strong year is a different negotiation from the original one.
Implementation is a multi quarter project that normally requires a systems integrator, so the first year cost is dominated by services rather than subscription, and the internal cost of finance and engineering time on catalogue and process design is larger still.
Product catalogue decisions made during implementation constrain what you can price and report for years, and changing them later means reworking live subscriptions and the revenue history attached to them rather than editing a configuration.
It is a subsidiary system rather than the general ledger, so someone has to own the reconciliation between billing, revenue and the accounts every period, and a mapping error surfaces as an unexplained variance in the close rather than as an obvious failure.
Billing and revenue are separate products with separate implementations, so a company that buys billing first and adds revenue later runs a second project against data models that were not designed together in the first place.

Answered from the vendors’ own pages

Kong: Does Kong offer a free trial?

Yes, Kong Konnect offers a 30-day free trial with full enterprise functionality, unlimited gateways, and no credit card required.

Zuora: When is a company ready for Zuora rather than a simpler billing tool?

When the pricing model breaks the simpler tool: mid term amendments, ramps, usage tiers, multi entity billing or a revenue recognition requirement. Companies with flat monthly plans and few changes do not need it and will not enjoy paying for it.

Kong: How much does Kong Insomnia Pro cost?

Kong Insomnia Pro is $12 per user per month with 15% savings available for annual billing.

Source

Zuora: Does Zuora replace our accounting system?

No. It is a billing and revenue subledger that posts journals to your general ledger. You still need the ledger and someone owning the reconciliation between them.

Kong: What are Kong Konnect Plus API request limits?

Kong Konnect Plus includes 1M API requests per month; additional requests cost $200 per 1M (maximum 10M per month).

Source

Zuora: How long does an implementation take?

Plan in quarters. Catalogue design, order to cash process definition, data migration of existing subscriptions and ledger mapping each take real time, and the migration of live contracts is usually the hardest part.

Kong: What is included in Kong Insomnia Enterprise?

Kong Insomnia Enterprise is $45 per user per month with SSO, SCIM, vault integrations, unlimited mock server requests, and Konnect integration.

Source

Zuora: Does it calculate sales tax and VAT?

It integrates with third party tax engines rather than maintaining rates itself. Budget for that engine as a separate subscription and a separate integration.

Zuora: What changed when the company was taken private in 2025?

Ownership, not the product. As with any private equity owned platform, pay attention to renewal pricing behaviour and to roadmap commitments made verbally rather than contractually.

Zuora: Can we migrate our existing subscriptions in?

Yes, and it is the part of the project people underestimate. Every live contract has to arrive with its amendment history intact if the revenue schedules are to be right, so the migration is an accounting exercise as much as a data one.
