What is code-stacking on Diaz Editor?

Code-stacking lets you redeem multiple marketplace codes (AppSumo) under one email address. Each additional tier adds seats to the same license rather than creating a new license. This is the standard marketplace pattern — stack 1 base code plus tier-2 or tier-3 codes for team-scale licensing.

How many seats does each tier add?

Tier 1 (base code) adds 1 seat — your starter license. Tier 2 adds 3 seats per code stacked. Tier 3 adds 10 seats per code stacked. A typical small-team stack: 1 × T1 + 1 × T2 = 4 seats. A typical agency stack: 1 × T1 + 2 × T3 = 21 seats.

What does 'Code already redeemed' mean?

Each marketplace code can only be redeemed once. If you see this error, either the code was already used (check the redemption email) or the code belongs to a different account. AppSumo verifies the redeemer at the marketplace level — codes cannot be transferred.

Why doesn't my second code add seats?

Most likely: you redeemed each code under a different email address, so they created two separate licenses instead of one stacked license. Email juan@diazatlas.com with both license keys and we will merge them. To prevent this, always redeem at diazatlas.com/redeem using the same email address each time.

Can I roll out a stacked license to my team?

Yes. After stacking, the license shows N seats in the License panel. Each team member installs Diaz Editor and activates with the same key — the seat counter decrements automatically. To free a seat (e.g. an employee leaves) use the Deactivate button on their machine, or revoke the seat from the team-admin License page.

What is code-stacking?

AppSumo sell Tier 2 + Tier 3 deals as multiple codes. Redeem each code separately at diazatlas.com/redeem with the same email. The system sees the match and automatically increases your seat-count.

Diaz Editor's Founding tier at diazatlas.com/beta is €99 lifetime (1 seat). That stays the lowest price ever — marketplaces have higher prices with exclusive bonus content (priority support, premium SVG icons, BAM-import templates).

Step-by-step stack flow

Redeem first code at diazatlas.com/redeem. Enter email + name. You get a license key via welcome email.
For 2nd code: go to /redeem again. Paste new code + exactly the same email as 1st time.
Backend sees same email → seat_count auto-increases. No new license key — you keep the same key.
You receive a stacking-confirmation email with new seat total.
Open Diaz Editor → menu License → Manage seats → see total seats + all stacked codes.

⚠ Critical: use the same email on every redemption. Different email = separate new license (no stack). When in doubt: email juan@diazatlas.com before redeeming.

Team rollout

One license key works on N devices (where N = seat_count). Each device fingerprints on first launch.

Send the license key + welcome email to each teammate
They paste the key on first launch via menu → License → "Enter key"
Their device shows up in your "Manage seats" list
Revoke: "Manage seats" → click "Revoke" next to a device (frees a seat for someone else)

Seat limit reached?

When activating an N+1 device without free seat:

Automatic: oldest device inactive ≥30 days drops automatically
Manual: revoke a device via "Manage seats"
Stack-up: buy an additional code on the marketplace and redeem it for +N seats

Common errors

"Code already redeemed"

The code was redeemed before (by you or someone else). Check welcome emails or email juan@diazatlas.com with the code to investigate.

Second code doesn't add seats

Usually: different email used. Check your inbox — did you receive 2 different welcome emails? Then 2 separate licenses were created. Email support for merge.

Seat-count is wrong in the app
