Control Traffic
KrakenD gives you granular, per-consumer rate limiting to protect your infrastructure from partner abuse. Strict request validation blocks malformed or out-of-scope requests before they reach your backends.
KRAKEND FOR BANKS & FINANCIAL INSTITUTIONS
Open Banking & Open APIs, Without Losing Control.
Regulations like PSD2 and Open Banking are forcing banks to expose APIs to third parties. The technical challenge is solvable. The real risk is governance: what happens when a partner abuses access, when audit scope expands, or when latency spikes during settlement windows. KrakenD is engineered to solve these problems at the architectural level.

Financial institutions and regulated enterprises rely on KrakenD to protect transactions, ensure uptime, and pass audits without architectural compromises.
Compliant by Design
Scale Open Banking Without Scaling Risk.
Open Banking mandates require exposing APIs to fintechs, aggregators, and partners. The tension is real: you must grant access while retaining absolute control over who gets what, how much, and when.
Predictable Pricing at Any Scale
Unlike gateways built on usage-based pricing, KrakenD does not charge per API call. Add partners, add traffic, add APIs. Your cost stays predictable while competitors penalize your growth.
Performance at Scale
Open Banking mandates require exposing APIs to fintechs, aggregators, and partners. The tension is real: you must grant access while retaining absolute control over who gets what, how much, and when.
Low Latency for Financial Workloads
Predictable Latency for Payments and Trading
In instant payments, real-time pricing, or trading workflows, every millisecond matters. But raw speed is not enough. Latency must be consistent.
KrakenD's stateless architecture eliminates the variability caused by database lookups and node synchronization. Each node operates independently with deterministic performance, even during market-opening spikes, settlement windows, or promotional campaigns.
Circuit breakers and fail-fast patterns contain failures instead of propagating them, protecting critical transaction flows when conditions are most demanding
Why Financial Institutions Trust KrakenD
Solving the Real Problems
of API-First Finance
KrakenD provides architectural solutions to the specific challenges banks face: audit burden, partner control, latency requirements, legacy modernization, and vendor independence.
Reduce Audit Scope by Design
Every component that stores data increases audit burden. PCI-DSS, SOX, and regulators require documentation for databases and control planes. KrakenD has no database, no control plane, no admin UI at runtime.
Configuration lives in Git with automatic audit trails. Other API gateways require PostgreSQL or similar that enter your audit scope. KrakenD eliminates this surface entirely.
Contain Failures, Protect Core Systems
In complex financial platforms, failures are inevitable. What matters is how far they propagate.
KrakenD prevents slow or unhealthy services from cascading into core banking systems through circuit breakers, fail-fast behavior, and strict request handling. Each node runs independently with no dependency on central coordinators, enabling true active-active deployments across regions.
No Vendor Lock-In, Ever
Banks have learned hard lessons from monolithic platforms. Architectural decisions must remain valid across technology shifts and regulatory changes.
KrakenD's core is donated to the Linux Foundation under open governance. Configuration is a portable JSON file. Switching from Enterprise to Community requires changing one line in your Dockerfile. That is not lock-in.
Modernize Legacy Without Rewrites
Core banking systems may be decades old, but mobile apps and Open Banking need modern APIs today.
KrakenD transforms SOAP to REST without code, aggregates multiple backends into single responses, and exposes legacy systems as AI-ready tools through MCP Server. No competitor offers this productized.

Why Choose KrakenD
For Banking & Finance?
No cloud dependency, self-hosted
KrakenD runs on-prem, in a private cloud, air-gapped, or across any public cloud. It integrates with existing observability, security, and CI/CD tooling. It does not send analytics or traffic outside your control
No data by design
KrakenD does not store customer data, credentials, tokens, or transaction payloads. There is no database, no persistent state, and no centralized control plane. This eliminates an entire class of data breach and insider risk scenarios and reduces compliance scope.
Instant modernization, no rewrites
KrakenD exposes legacy core banking systems as modern microservices without manual work. Convert SOAP to REST, expose services as MCP tools for AI agents. Modernize incrementally without backend coupling.
Flat-rate pricing that rewards growth
Unlike other API gateways, KrakenD does not charge per API call or per partner. Scale Open Banking traffic without scaling costs. Predictable pricing for CFOs, unlimited growth for engineering.
Proven in high-trust environments
Used by Fortune 500 companies, global enterprises, and financial institutions operating at massive scale.
Reliable premium support
Provided by the engineers building KrakenD (not trained post-sales staff), including dedicated success engineer, onboarding, Slack channel, video calls, and code reviews.
