Atarim vs Leantime: at a glance
What is Atarim?
Atarim's AI experts now propose changes to live pages as drafts, and the app runs on phones.
Atarim 5.1.4 extends the draft-first rule from new pages to edits on live pages: an AI specialist's fix comes back as a draft copy with a preview link, and the task waits in Pending review until a person approves it. Atarim now also works on phones and tablets and installs as an app. The previous release, 5.1.3, rebuilt Boards with a timer on every stage.
What is Leantime?
Leantime is stabilizing its big 3.9 rewrite while extending cross-project planning and a mobile API
Leantime is deep in a modernization cycle. The 3.9.0 release rebuilt the app around a native, fail-closed permission engine, a JSON-RPC API, and a consolidated Blueprints domain; the releases since then mostly stabilize that foundation. Recent point releases fix regressions (repeated Bearer/PAT auth fixes) while adding cross-project program views and a mobile app backend.
Atarim vs Leantime: editorial side-by-side
Atarim
5.0PM
Atarim's AI experts now propose changes to live pages as drafts, and the app runs on phones.
◆ Current state
Atarim 5.1.4 extends the draft-first rule from new pages to edits on live pages: an AI specialist's fix comes back as a draft copy with a preview link, and the task waits in Pending review until a person approves it. Atarim now also works on phones and tablets and installs as an app. The previous release, 5.1.3, rebuilt Boards with a timer on every stage.
◆ Where it's heading
Atarim keeps pairing more AI autonomy with more human control: readable memory in 5.1.2, stage clocks in 5.1.3, and now mandatory approval on live changes. The mobile app moves that approval step to wherever the agency owner is, which fits a model where AI does the work and people sign off.
◆ Prediction
Expect approval and review to tie into Boards, for example pending AI drafts showing up as a stage with its own clock.
Leantime
6.3PM
Leantime is stabilizing its big 3.9 rewrite while extending cross-project planning and a mobile API
◆ Current state
Leantime is deep in a modernization cycle. The 3.9.0 release rebuilt the app around a native, fail-closed permission engine, a JSON-RPC API, and a consolidated Blueprints domain; the releases since then mostly stabilize that foundation. Recent point releases fix regressions (repeated Bearer/PAT auth fixes) while adding cross-project program views and a mobile app backend.
◆ Where it's heading
The work is consolidation over expansion: hardening the new auth/permission and API layers, closing security IDORs domain by domain, and building the surface a mobile app and program-level planning need. The steady stream of small patch releases reflects shaking out regressions from the 3.9.0 refactor rather than opening new product directions.
◆ Prediction
Expect continued point releases fixing regressions from the permission-engine and JSON-RPC migration, plus buildout of the Leantime Mobile app now that its Bearer-authenticated backend API is landing.
