Marble is an open-source Transaction, Event, and User real-time engine designed to help companies detect money laundering, service abuse or fraud behavior.
We provide an easy-to-use rule builder that can leverage any type of data, an engine capable of running checks in batch or in real-time, and a case manager to improve operational efficiency.
Marble is beneficial for payment service providers (PSPs), banking-as-a-service (BaaS) providers, neo banks, marketplaces, telecommunications companies... It allows them to quickly set up and update detection scenarios that generate decisions within minutes.
These decisions can trigger events in your systems, introduce friction, or restrict operations in real-time. They can also be investigated within Marble using our case manager or in your own system by utilizing our API.
Marble is developed with compliance requirements in mind, ensuring that everything is versioned and auditable without any time limitations.
Open-source, open architecture:
- Composable: Connect Marble to any of your internal systems or tools, such as transaction databases, KYC solutions, or 3rd party data providers.
- Pricing: Our self-hosted version is free. Our cloud version is priced like a SaaS and is surprisingly cheaper than market leaders.
- Privacy: Your data never has to leave your infrastructure.
NB: We do not provide KYC services. There are plenty of awesome players in the market that you can connect with :)
Marble core features
- Create detection scenarios based on rules.
- Run those scenarios in batch or real-time to generate decisions.
- Investigate decisions in your own system or within Marble's case manager.
- Manage custom lists such as known users, VPN IPs, and keywords.
- Create any type of data model to feed into Marble.

Planned on roadmap
- Backtest: check scenario efficiency on your past data before pushing to production
- Supervised Machine Learning: use previous results to create a custom ML detection model
- Advanced connectors for unstructured data: use documents, GPS points, images… in your rules.
The core of the decision engine is available in open-source, but some advanced features are only accessible with a lincense (in our cloud offering or on-premise). You can find the list of available features in our pricing page.
As long as you are runnig Marble locally with a test setup (using the Firebase auth emulator for end user authentication), you will see all the features, but you will be restricted if you authenticate with a real Firebase auth app.
Marble's incredible flexibility is due to its fully open data model. Here are some applications already in use with Marble:
- Transaction monitoring for financial institutions (AML & fraud), supporting every type of payment scheme (including the exotic ones: Marble handles any type of data).
- User/account monitoring.
- User risk score calculation at onboarding and throughout their lifecycle.
- Event scoring: adding new beneficiaries, subscribing to new products, etc.
- Vendor/buyer checks for marketplaces: return abuse, fake transactions, etc.
- Condition abuse: robocalling for telecom companies, bot management on social networks and apps.
- Embedded in financial SaaS: fine control of expenses for end users.
Feel free to try other use cases and let us know! We'd love to hear from you.
The following instructions are for a docker-compose setup. You can also take inspiration from the terraform templates provided in the repository to create a serverless GCP deployment of Marble, inspired by Marble's own cloud deployment.
Simply clone this repository and run docker compose --env-file .env.example up (customize the .env-example file or provide your own copy).
It will run out of the box with the firebase auth emulator. If you wish to run Marble open-source in production, you will need to create a firebase auth app.
The first time you run the code, you should enter an organization name and organization admin user email to create using the CREATE_ORG_NAME and CREATE_ORG_ADMIN_EMAIL environment variables. Unless using the firebase emulator, you must enter an actual email address that you own so that you may verify it and login with firebase. You can always create new organizations later using the same procedure.
In a local demo setup:
In a local test setup (meaning if you are running with the firebase auth emulator), the License key is not required. You can leave it empty. The full feature set is available.
- just run the docker-compose as it is, it should work
- give the firebase emulator a moment to get started, it's a bit slow when first launched
- create a Firebase user with the email you provided in the
CREATE_ORG_ADMIN_EMAILenvironment variable (you can do this on the Marble login page by using the SSO button or sign up with email)
In a production setup:
- set the
FIREBASE_AUTH_EMULATOR_HOST_SERVERandFIREBASE_AUTH_EMULATOR_HOST_CLIENTenv variables to empty strings in your .env file - create a Firebase project and a Firebase app, and set the relevant env variables (
FIREBASE_API_KEYtoFIREBASE_APP_IDas well asGOOGLE_CLOUD_PROJECT) in your .env file - if you plan to use the batch ingestion feature or the case manager with file storign feature, make sure you create the Google Cloud Storage buckets, set the corresponding env variables and run your code in a setup that will allow default application credentials detection
- create a Firebase user with the email you provided in the
CREATE_ORG_ADMIN_EMAILenvironment variable (you can do this on the Marble login page by using the SSO button or sign up with email) - if you have a license key, set it in the
LICENSE_KEYenv variable in your .env file
Open the Marble console by visiting http://localhost:3000, and interact with the Marble API at http://localhost:8080 (assuming you use the default ports). Change those values accordingly if you configured a different port or if you are calling a specific host.
You will find a functional documentation of how to use Marble here, and the documentation of our public API here.
Risk management is challenging for many companies. Currently, you can either:
- Build your own risk infrastructure:
- It’s a never-ending task.
- Building from scratch takes months and often falls short of end-user expectations.
- Essential elements like versioning and audit trails are often overlooked.
- Risk teams need updates urgently, but development teams need to scope and prioritize first.
- Or, spend a significant amount to buy a service where:
- Setup costs and time are substantial.
- You might lack full control over the applied rules.
- The scoring algorithm is “proprietary,” meaning you can’t explain it.
- There’s limited flexibility to connect your data and product specifics, such as limited payment schemes covered.
- Contract renewal is burdensome.
Marble offers a clear third option:
- Start Strong: Benefit from one of the best engines on the market for free. There’s no excuse for not having top-notch monitoring from day one.
- Privacy: Your data remains yours, always.
- Total Transparency: The code is open; you can see everything within the engine. You KNOW why an alert is raised every time; you don’t have to guess.
- Evolutivity: Use any data you want and evolve the model instantly. Adding a new product, even with a never-before-seen payment scheme, takes minutes.
- Community Driven: Contribute based on your needs: need a custom calculation? A third-party integration? It’s just a commit away.
We want to create an open environment and appreciate all types of contributions that benefits all current and future users. Here are some ways you can contribute:
- Give us feedback in our Slack community
- Help with bugs and features on our Issues page
- Submit a feature request or bug report
