Leantime is a self-hostable project management platform designed around Lean and Agile practices. It helps teams plan strategy, define goals, manage projects, and track execution using a mix of roadmaps, boards, and task workflows. Leantime targets small-to-mid sized teams and agencies that need a lightweight PM tool with client-friendly collaboration features.

Key Features

  • Strategy and planning modules (ideas, goals, milestones/roadmaps) to connect execution to outcomes
  • Kanban-style task boards with statuses and swimlanes for day-to-day work management
  • Backlog and sprint-style workflows for iterative delivery
  • Time tracking and timesheets per task/project for billing and reporting
  • Project documentation features (wikis/notes) to keep context with work items
  • Role-based access and multi-user collaboration across multiple projects
  • Client collaboration options (invite external users to selected projects)
  • Integrations via webhooks/API support (where configured) and email notifications

Use Cases

  • Manage product development with a roadmap → backlog → sprint/board workflow
  • Run an agency with per-client projects, task-level time tracking, and shared status visibility

Limitations and Considerations

  • Feature depth is typically lighter than enterprise suites (advanced portfolio management and extensive native integrations may require customization)

Leantime provides an opinionated Lean/Agile structure that connects higher-level planning to tasks and delivery. It is suitable for teams wanting an integrated roadmap/kanban/time-tracking tool without adopting heavier enterprise project platforms.

Wakapi is a self-hosted server that collects coding activity from IDE/editor plugins using the WakaTime API protocol, then stores and visualizes the data in a web UI. It is designed as a privacy-focused alternative to hosted time-tracking/telemetry services, with multi-user support and exportable reports.

Key Features

  • WakaTime-compatible API for seamless use with existing WakaTime editor/IDE plugins
  • Web dashboard with time stats by project, language, editor, operating system, and time ranges

  • Goal tracking and summaries (e.g., daily/weekly targets and progress)
  • Export and reporting (e.g., JSON/CSV-like exports and shareable views depending on configuration)
  • Optional integrations (e.g., Prometheus metrics endpoint / observability hooks where supported)
  • Multiple database backends (commonly SQLite by default; can be configured for others)
  • Container-friendly deployment (Docker/Docker Compose images and straightforward configuration)

Use Cases

  • Track personal coding time across devices without sending data to third-party SaaS
  • Provide an internal coding-activity dashboard for a team or organization
  • Maintain historical engineering activity data for retrospectives and personal improvement

Limitations and Considerations

  • Requires editor plugins that speak the WakaTime protocol; feature parity depends on plugin capabilities
  • Some advanced analytics found in commercial services may be limited or require external tooling

Wakapi is a practical drop-in backend for WakaTime-compatible clients that prioritizes data ownership and local control. It fits individuals and teams who want transparent, exportable coding-activity insights with minimal setup overhead.
