What is Aha!?

Elle stops being Aha's assistant and becomes where teams encode their own standards.

Aha! publishes a steady run of concrete, narrow features across Roadmaps and Builder as one-line update posts, interleaved with occasional product-management essays. This window covers user groups for mentions and assignment, a design system for AI-generated apps, long-document handling, virtual user testing for prototypes, and user-defined skills for the Elle assistant. Aha! Builder, which turns plans into working applications, is absorbing most of the AI investment.

What is Vikunja?

Vikunja crossed the v1.0 finish line and pivoted hard into security hardening.

Vikunja shipped two v1.0 release candidates through late 2025 and early 2026, then jumped to a v2 series whose first widely-tagged point release, v2.2.1, is dominated by security work. The latest release patches multiple SSRF and IDOR vulnerabilities, enforces disabled/locked-account semantics across every auth surface (OIDC, API tokens, CalDAV, LDAP), and adds a shared SSRF-safe HTTP client that webhooks and migrations now route through. User-facing feature work has slowed; the visible energy is in plumbing and audit cleanup.

Aha! vs Vikunja: editorial side-by-side

A6.3

Elle stops being Aha's assistant and becomes where teams encode their own standards.

◆ Current state

Aha! publishes a steady run of concrete, narrow features across Roadmaps and Builder as one-line update posts, interleaved with occasional product-management essays. This window covers user groups for mentions and assignment, a design system for AI-generated apps, long-document handling, virtual user testing for prototypes, and user-defined skills for the Elle assistant. Aha! Builder, which turns plans into working applications, is absorbing most of the AI investment.

◆ Where it's heading

The arc is legible across three months: Aha! held the product data, then exposed it through an MCP server in May, then acted on it when Builder began generating applications in June, and now lets customers define how the assistant behaves. Skills make Elle configurable by the teams using it rather than only by Aha!, which repeats for the assistant what Builder did for applications. The Roadmaps side meanwhile keeps receiving unglamorous collaboration and document work, so the classic tool is not being starved while the AI half expands.

◆ Prediction

Skills are the obvious thing to extend next, most likely with sharing or governance controls, since Aha! sells to organizations that standardize process. On the Builder side, testing landed in July and deployment and handoff remain the visible gaps.

V0.0

Vikunja crossed the v1.0 finish line and pivoted hard into security hardening.

◆ Current state

Vikunja shipped two v1.0 release candidates through late 2025 and early 2026, then jumped to a v2 series whose first widely-tagged point release, v2.2.1, is dominated by security work. The latest release patches multiple SSRF and IDOR vulnerabilities, enforces disabled/locked-account semantics across every auth surface (OIDC, API tokens, CalDAV, LDAP), and adds a shared SSRF-safe HTTP client that webhooks and migrations now route through. User-facing feature work has slowed; the visible energy is in plumbing and audit cleanup.

◆ Where it's heading

The arc moves from feature-completion (S3 storage, drag-and-drop project moves, hover previews in late 2025) toward platform credibility — closing security gaps a self-hosted task tool needs to clear before serious team adoption. The rapid version-number jump from v1.0.0-rc4 to v2.2.1 in two months suggests v1.0 shipped and the team tagged a v2 line aimed at addressing accumulated authz debt. Expect the next several releases to keep the security-first posture rather than return to a feature push.

◆ Prediction

The next release will likely continue closing remaining authz edges (more IDOR audits, additional credential-stripping in API responses) and bundle a translations and dependency sweep. A user-facing feature push probably waits until the security work plateaus.
