ActiveCollab vs Leantime: at a glance
What is ActiveCollab?
ActiveCollab went AI-native by shipping an MCP Server — your AI assistant can now act inside the workspace.
ActiveCollab has been shipping at a high cadence: a Model Context Protocol (MCP) server that lets external AI assistants log hours, comment, and mark tasks done; a redesigned Cost Summary Report with period and job-type/team-member grouping; a new Capacity and Utilization report; revamped Add-Ons; and a cleaner API-token management experience. The self-hosted 8 release (early February) brought over 100 features and a lighter installer for customers who run their own deployment.
What is Leantime?
Leantime lands a major architecture rebuild, then spends a week stabilizing its API auth
Leantime is working through the aftermath of 3.9.0, a large architectural release that introduced a native permission engine, a JSON-RPC API layer, consolidated 16 canvas variants into a unified Blueprints domain, and added mobile push notifications. The subsequent 3.9.1-3.9.5 train is dominated by fixing Bearer/token authentication regressions that release introduced.

The self-hosted 8 release (early February) brought over 100 features and a lighter installer for customers who run their own deployment.
◆ Where it's heading
ActiveCollab is taking the unusual position of being AI-action-ready before AI-summary-ready: the MCP server treats the product as a tool callable by Claude, ChatGPT, or Copilot rather than baking in its own LLM. In parallel, the team is investing in services-firm primitives (capacity planning, utilization, cost reports, invoicing) and a viable self-hosted SKU. That combination — agency operations, AI-tool-callable, self-hostable — is a credible niche against Asana, Monday and ClickUp, none of whom currently expose an MCP surface.
◆ Prediction
Watch for an MCP-server marketplace listing or template gallery (so it shows up in Claude/ChatGPT directories), MCP-aware UI affordances inside ActiveCollab to surface AI-driven activity, and continued self-hosted polish to keep that audience loyal. AI-generated subtask suggestions are the obvious bolt-on.

Leantime lands a major architecture rebuild, then spends a week stabilizing its API auth
◆ Current state
Leantime is working through the aftermath of 3.9.0, a large architectural release that introduced a native permission engine, a JSON-RPC API layer, consolidated 16 canvas variants into a unified Blueprints domain, and added mobile push notifications. The subsequent 3.9.1-3.9.5 train is dominated by fixing Bearer/token authentication regressions that release introduced.
◆ Where it's heading
The open-source PM tool is modernizing its foundation (thin controllers, typed exceptions, fail-closed authorization, Blade migration) to support a mobile app and third-party integrations. The near-term cost is a visible bugfix tail as token-based auth gets hardened path by path.
◆ Prediction
Expect the patch cadence to settle once Bearer-auth coverage stabilizes, with mobile endpoints and the JSON-RPC surface becoming the focus, given the mobile API work threaded through these releases.
