Detailed Introduction

Leantime is an open source project management system built specifically for non-project managers. It combines strategic planning, goal tracking, and daily execution in one simple interface. Designed with ADHD, dyslexia, and autism in mind, Leantime offers kanban boards, Gantt charts, timeline views, tables, calendars, wikis, goal dashboards, time tracking, and retrospective tools. It supports unlimited subtasks, dependencies, milestones, sprints, and integrations with Slack, Mattermost, Discord, LDAP, OIDC, and more. Available in 20+ languages and extendable via plugins and API. Compared to Trello, it provides rich project planning features; compared to Jira, it offers much simpler usability.

Troubleshooting & FAQ (2)

Troubleshooting
How to fix 'could not find driver' error when connecting Leantime Docker image to PostgreSQL?

The official Leantime Docker image (v3.6.0 and earlier) lacks the PostgreSQL PDO driver, causing 'PDOException: could not find driver' when LEAN_DB_TYPE=postgres is set. As a workaround, rebuild the image with the driver:

FROM leantime/leantime:3.6.0
USER root
RUN apk add --no-cache libpq libpq-dev && docker-php-ext-install pdo_pgsql && apk del libpq-dev
USER www-data

A proper fix is staged in PR #3447 and will be included in v3.7.0+ releases. For now, use the custom Dockerfile or wait for the official update.

GitHub Issue #3212
Troubleshooting
Why does Leantime throw 'duplicate key value violates unique constraint' on first user login with PostgreSQL?

After a fresh install on PostgreSQL, the installer inserts seed data (admin user, demo tickets) with explicit IDs, but doesn't update the BIGSERIAL sequences. When a new user signs in for the first time, the next auto-generated ID collides with the existing row. Workaround: manually resync sequences by running SETVAL for each table to the current max(id)+1, e.g. SELECT setval(pg_get_serial_sequence('zp_user','id'), (SELECT MAX(id) FROM zp_user)); repeat for zp_clients, zp_projects, zp_canvas, zp_canvas_items, zp_relationuserproject, zp_tickets. A permanent fix is staged in PR #3447.

GitHub Issue #3380
