LeanZero

Two people in Romania doing Atlassian migrations, Forge apps and practical AI work for teams that would rather talk to the person doing the job. Most of what we learn ends up on this site.

LeanZero's first year: four Forge apps on the Atlassian Marketplace

Gabriela and I have spent our careers in consultancies watching what goes wrong, so we started LeanZero. Ten months after the website went live, the two of us have four Forge apps on the Atlassian Marketplace, and I had our AI agents rewind the site to show how we got here.

“This app might stop working soon”: what admins do before Connect end of support

Connect end of support begins on 31 January 2027. On our test site the Connected apps page tagged 4 of 57 entries Legacy, said January 2027 in its banner and December 2026 in its tooltip, and had no column or tag saying Connect or Forge. Here's how to find your affected apps and what to ask each vendor.

Find inactive users in Jira and Confluence: the free way, and the Cost Slasher beta

Atlassian bills every user with app access, and list prices rose on 13 October 2026. You can find inactive users in Jira and Confluence for free with Atlassian's export. Cost Slasher, our new beta, adds per-app inactivity policies and time away. It removes no one for inactivity until you verify it.

Atlassian license management by prompt: what CogniRunner's Jira AI agents can do now

A CogniRunner AI agent set up from one paragraph, then given a plan I tightened by hand, counted 32 Atlassian products on 17 sites. A second agent took one Confluence license away only after a person approved. Plus a workflow validator that stopped Claude Code twice, a Forge app deployed through Bitbucket Pipelines, the safety design and the token bill.

Atlassian Team '26 Europe on demand: the keynotes and sessions worth watching

Atlassian Team '26 Europe on demand: six keynotes are free on Atlassian's YouTube channel, the rest is in the on-demand library behind a free sign-in, and these are the sessions I'd watch as a Forge builder or Jira admin.

Atlassian Team '26 Europe Founder Keynote: agents on the Jira board, then a power cut

The Team '26 Europe Founder Keynote as I saw it from the hall in Amsterdam on Wednesday 7 October: agent sessions from Cursor, Codex and Claude Code on a Jira board, AMP, a lot of Rovo, a power cut, and a day showing our Forge apps to Atlassian's people.

Atlassian Partner Accelerate at Team '26 Europe: Forge, revenue share and who we met

Atlassian Partner Accelerate, the partner-only day before Team '26 Europe, was for us a day of meeting solution partners and other Forge app builders. Here is what was on the screens about Forge and Teamwork Graph, the Marketplace revenue share that applies from 1 October 2026, the partner tiers, how we shared LeanZero by QR code, and a little of Amsterdam.

"Uncaught (in promise) Error: Unable to emit ready event." in a Forge Confluence macro

You added emitsReadyEvent to a Confluence macro to speed up PDF export, called view.emitReadyEvent(), and every normal page view now logs "Unable to emit ready event." The shipped @forge/bridge source says why it happened, why it was harmless, and which version made it stop.
