Keploy vs Panaya
Keploy auto-generates API tests from real production traffic using eBPF with zero code changes, while Panaya specializes in ERP change impact analysis for SAP and Oracle. Keploy suits API-heavy microservices teams; Panaya serves enterprise ERP teams needing upgrade and migration testing with pre-built business process coverage.
How They Work Differently
Architectural differences that affect your team's workflow, cost, and velocity.
KeployKeploy captures live API traffic using eBPF and converts it into reusable integration tests with auto-generated mocks. It requires zero code changes and handles non-deterministic data through time-freezing and normalization. This approach works across any language or framework in microservices environments.
PanayaPanaya analyzes ERP system configurations and business processes to identify the impact of changes in SAP and Oracle environments. It provides pre-built test cases tied to ERP modules and automates regression testing for upgrades and patches. The platform is purpose-built for enterprise resource planning workflows.

PanayaWhen to Use Each Tool
Specific scenarios where each tool delivers the most value for your engineering team.
Keploy is the better fit when you need to...
- Your architecture is API-heavy microservices rather than monolithic ERP
- You need language-agnostic test generation without vendor lock-in
- You want to capture real production traffic patterns as tests automatically
- Your team values open-source tooling with self-hosted deployment options
- You need mock/stub generation for complex dependency chains
Panaya is the better fit when you need to...
- Your primary systems are SAP or Oracle ERP and you need change impact analysis
- You require pre-built business process test coverage for ERP modules
- Your testing focus is ERP upgrades, patches, and migration validation
- You need compliance-grade audit trails for regulated ERP environments
- Your team lacks API testing expertise but has deep ERP domain knowledge
Real-World Scenarios
How each tool handles the challenges your team actually faces.
ERP-to-Microservices Migration Testing
Keploy captures API traffic between new microservices and legacy ERP endpoints, generating regression tests that validate data consistency during the migration. Auto-generated mocks let you test services independently of the ERP system.
Panaya maps existing ERP business processes and identifies which transactions are affected by the migration. It provides pre-built test scenarios for the ERP side but cannot generate tests for the new microservices layer.
Post-Deployment API Regression Suite
Keploy replays captured production traffic against new deployments, catching regressions in API contracts and response payloads automatically. The test suite grows organically as new traffic patterns are captured.
Panaya runs change impact analysis within the ERP to identify affected business processes after a patch or upgrade. Tests are scoped to ERP modules and do not cover custom API integrations.
Third-Party Integration Validation
Keploy generates mocks for third-party payment gateways and shipping APIs, allowing teams to test integrations without hitting external services. Non-deterministic fields like timestamps are automatically normalized.
Panaya validates third-party integrations only within the ERP context, such as EDI or bank statement imports. It does not mock external services or handle REST/GraphQL API integrations.
FAQs
Keploy can capture and test any HTTP/gRPC API traffic, including APIs exposed by SAP or Oracle systems. However, it does not provide ERP-specific change impact analysis or pre-built business process coverage like Panaya does. Keploy is best suited for testing the API layer around ERP systems rather than internal ERP transactions.
Panaya is purpose-built for ERP environments and does not support general-purpose microservices or API testing. If your architecture includes both ERP and microservices, you may need Panaya for ERP change management and a tool like Keploy for API-level testing.
Panaya is the stronger choice for SAP S/4HANA migrations because it provides pre-mapped business process test coverage, change impact analysis, and SAP-specific regression testing. Keploy would complement this by testing custom APIs and integrations built around the SAP system.
Yes. Teams with hybrid architectures often use Panaya for ERP-specific change management and testing while using Keploy to capture and test API traffic between microservices and ERP endpoints. The tools address different layers of the stack.
Keploy offers a free open-source core under Apache 2.0 with optional paid enterprise features. Panaya uses enterprise subscription pricing based on the number of ERP systems and users. For teams primarily doing API testing, Keploy is significantly more cost-effective. For dedicated ERP testing, Panaya's pricing reflects its specialized capabilities.
Looking for a Panaya Alternative?
Engineering teams evaluating Panaya alternatives often compare it with Keploy for API testing and regression coverage. Keploy captures real production traffic via eBPF and auto-generates tests with dependency mocks — requiring zero code changes. If you're considering switching from Panaya or comparing Panaya and Keploy side by side, the key differences come down to how tests are generated (traffic-based vs manual), how dependencies are mocked (automatic vs configured), and what infrastructure changes are needed (none vs SDK/sidecar/containers).
