Licence Key

How to enter your licence key

After purchase you receive a key in the format PRO-XXXX-XXXX-XXXX-XXXX or ENT-XXXX-XXXX-XXXX-XXXX.

Method 1 — Command-line flag

bash
./build/absdb-server \
  --license-key=PRO-XXXX-XXXX-XXXX-XXXX

Simplest for testing. Key is visible in ps aux output.

Method 2 — Environment variable (recommended)

bash
export ADB_LICENSE_KEY=PRO-XXXX-XXXX-XXXX-XXXX
./build/absdb-server

Key is not visible in process listing — preferred for production.

Method 3 — systemd service

bash
sudo systemctl edit absdb

# Add under [Service]:
[Service]
Environment="ADB_LICENSE_KEY=PRO-XXXX-XXXX-XXXX-XXXX"

sudo systemctl restart absdb

Method 4 — Docker

bash
docker run -d \
  -e ADB_LICENSE_KEY=PRO-XXXX-XXXX-XXXX-XXXX \
  -p 5433:5433 -p 8080:8080 \
  absdb/absdb:7.5.2

Verify your licence

bash — verify edition after starting server
# Health endpoint
curl -s http://localhost:8080/health
# → {"healthy":true,"version":"7.5.2","status":"running"}

# Via psql
psql -h localhost -p 5433 -U $(whoami) -c "SELECT absdb_version();"
#  absdb_version
# ───────────────
#  7.5.2

FAQ

Common questions

Is the Community edition really free?

Yes. Community is free for personal use, education, and open-source projects — non-commercial only. For commercial use, the SME Free tier is free for businesses with annual revenue under USD $1,000,000. No sign-up, no telemetry, no expiry on either tier.

Do cloud providers need a special licence?

No. AWS, GCP, Azure, and any managed DBaaS operator can offer Absolute DB under a standard Professional or Enterprise licence. No separate cloud provider agreement is required.

What's the binary format for the licence key?

Keys are in the format PRO-XXXX-XXXX-XXXX-XXXX (Professional) or ENT-XXXX-XXXX-XXXX-XXXX (Enterprise). Pass via --license-key=<key> or $ADB_LICENSE_KEY env var.

Can I try Professional before buying?

Email sales@absolutedb.com for a 30-day trial key. No credit card required during trial.

Is there a per-seat or per-CPU pricing?

Professional is per server (one running absdb-server process). Enterprise is per cluster. No per-CPU or per-seat fees.
