Two ways to use it

Use it in the cloud, or deploy it yourself

Same single-site feature set. The difference is who runs the server and where the data lives.

Cloud Free

Activate it on MeetCarbon Cloud with no server to prepare. A quick way to connect one site’s meters and start reading data.

No servers or operations
Up to 50 meters
90-day data retention

Apache-2.0

Self-hosted CE

Deploy the source on your own server with Docker Compose. Data stays entirely on your side, and you can extend the code.

Open source, modify and extend freely
Starts with one Docker Compose command
Meter scale set by your hardware
You decide how long data is kept

Request the source

Until the source repository is public, leave a request on our website and we will send you access.

Quick start

Running in three steps

Demo data is included, so you can see every page before connecting real devices.

Install Docker

Install Docker Desktop or Docker Engine and make sure docker compose works.

Start the services

From the source root, go into deploy, then build and start the stack.

$cd deploy
$docker compose up --build

Open the browser

The app is on port 8080; the API health check is on port 8081.

http://localhost:8080

Develop separately

# API
$cd server && SEED_PATH=../deploy/seed/demo.json go run .
 
# Web (/api proxied to 8081)
$cd web && npm install && npm run dev

Choosing

Who it’s for, and when to upgrade

Community Edition fits

Starting with one site

One building, plant or switchroom: connect the meters and start reading data.

Integrators and developers

Connect acquisition devices, verify the data path, or build on the source.

Teaching and training

Universities and training centers use it for energy management courses and labs.

Trial before selection

Evaluate the real pages before a project is formally approved.

Consider Enterprise when you need to

Manage several parks, buildings or plants on one platform
Run prepaid metering and bills for tenants
Monitor electrical safety, power quality or fire alarms
Edit HMI diagrams, run O&M tickets or build custom reports
Have a formal contract, on-site delivery and service guarantees

FAQ

About the Community Edition

Is the Community Edition free?

Both cloud Free and self-hosted CE are free to use. The source is licensed under Apache-2.0, so you can modify and extend it.

How do cloud Free and self-hosting differ?

Same single-site feature set. Cloud Free is hosted on MeetCarbon Cloud with up to 50 meters and 90-day retention; self-hosted runs on your own server, with scale and retention up to you.

Which devices can it connect?

CE ships with a simulated data source for demos and testing, and supports a limited set of acquisition protocols. For many field devices or complex protocols, choose Enterprise and we will assess the connection path.

Can I use the MeetCarbon name in commercial delivery?

The code is Apache-2.0; the names and logos are not covered. You may state that your work derives from MeetCarbon EMS Community Edition, but not claim official certification or delivery by us. Trademark licensing can be requested through our website.

Is there technical support?

CE is community self-serve; tag your questions ems-ce. Enterprise comes with a formal contract and on-site delivery.

How can I contribute?

Issues and code are welcome. Code contributions need a DCO sign-off (Signed-off-by) in each commit.

Start with one site

Activate it free in the cloud, or request the source and deploy it yourself. For multiple projects and on-site delivery, book an Enterprise demo.
