Version pages, supported modules, and example flows are visible on the site so buyers can verify protocol scope before they talk to sales.
Review protocol pagesABB, EVBox, Wallbox, Alfen, GIREVE, Hubject
Vendor and roaming-partner pages make it easier to see whether OCPPLab matches the exact charger or hub workflows your team needs to validate.
See integrationsLogs, workflows, charger profiles
The site already shows protocol logs, workflow editing, and charger-profile screens so buyers can judge whether the product is operationally useful, not just conceptually interesting.
Explore featuresDeveloper, Professional, Enterprise
Pricing and plan-fit sections explain which plan matches early validation, release QA, or enterprise-scale rollout work instead of making buyers decode a pricing table alone.
Compare plansCloud now, on-prem or hybrid when needed
Smaller teams can start in the cloud, while Enterprise buyers can discuss on-premises or hybrid deployment plus dedicated support before procurement starts.
Talk through deploymentTrial or demo path
A technical buyer can start with a self-serve trial path for early validation or book a scoped demo when vendor coverage, roaming, or support requirements are more complex.

These are representative evaluation paths based on the kinds of OCPP and OCPI workflows teams need to validate. They are examples of how buyers usually inspect product fit, not named customer case studies.
Representative scenario 01
CSMS release team
A backend team wants confidence that a CSMS release will not break charger onboarding, transactions, or smart charging across both legacy and newer fleets.
What they usually verify
Representative scenario 02
Roaming interoperability team
A roaming team needs to validate credentials, tariffs, sessions, and CDR exchanges before a new OCPI connection reaches a real partner or certification path.
What they usually verify
Launch virtual chargers quickly, inspect protocol traffic, and validate backend changes before you push them into a real charger fleet.

OCPP Simulator
An OCPP simulator is a virtual charge point simulator that reproduces how EV chargers talk to a Charge Station Management System over OCPP. Teams use it to validate BootNotification flows, authorization, transactions, meter values, smart charging, firmware updates, and failure recovery before deploying changes to production chargers.
OCPPLab is a cloud-based OCPP simulator built for CSMS teams that need scale as well as protocol realism. It supports OCPP 1.6, OCPP 2.0.1, OCPI 2.1.1, and OCPI 2.2.1, lets you launch 10,000+ virtual charge points, and helps engineering teams replace slow hardware-lab cycles with repeatable cloud testing.
Protocol Coverage
The commercial pages now call out the exact protocol versions teams search for most often: OCPP 1.6, OCPP 2.0.1, OCPI 2.1.1, and OCPI 2.2.1. That makes the homepage clearer for both buyers and crawlers.
Validate charger onboarding, authorization, transactions, status notifications, meter values, and remote commands for widely deployed OCPP 1.6 fleets.
Test modern OCPP 2.0.1 workflows including smart charging, device management, security profiles, ISO 15118-adjacent flows, and TransactionEvent handling.
Cover core roaming interoperability for credentials, locations, sessions, CDRs, tariffs, tokens, and commands between CPOs and eMSPs.
Validate newer roaming and hub workflows including ChargingProfiles, HubClientInfo, richer tariff structures, and broader hub interoperability requirements.
OCPP Simulator vs Emulator
EV charging teams often use OCPP simulator and OCPP emulator interchangeably. In practice, teams searching for an OCPP simulator usually need more than a single-device mock: they need realistic charger behavior, repeatable scenarios, protocol assertions, and enough scale to test their CSMS under pressure.
OCPPLab covers both needs. You can emulate individual charger behaviors for debugging and also simulate large fleets for regression testing, performance analysis, and release validation.
They usually want a virtual charge point platform that can run many chargers, automate scenarios, and support CSMS testing in CI/CD.
They often mean a charger-behavior replica for protocol debugging, integration checks, and reproducing vendor-specific edge cases.
It gives you vendor-aware charger profiles, observability, AI-assisted QA, and fleet-scale OCPP load testing from one cloud platform.
You do not need separate tools for debugging, certification prep, and scale validation before shipping CSMS releases.
