Aha!
Aha! is hardening Builder from a PM prototyping toy into a governed internal-app platform.
A side-by-side editorial comparison of Vikunja and Notesnook — release velocity, themes, recent moves, and the top alternatives to consider.
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.
Notesnook ships steady point releases across desktop and Android, with hotfixes close behind
Notesnook is on a tight release cadence across desktop and Android, moving through the v3.3.x line. The recent window is dominated by maintenance: a desktop and an Android hotfix both addressing a 'file size is 0' attachment-upload bug, plus routine point releases whose details live on the changelog blog.

User-facing feature work has slowed; the visible energy is in plumbing and audit cleanup.
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.
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.
Notesnook is on a tight release cadence across desktop and Android, moving through the v3.3.x line. The recent window is dominated by maintenance: a desktop and an Android hotfix both addressing a 'file size is 0' attachment-upload bug, plus routine point releases whose details live on the changelog blog.
The pattern is incremental hardening of the encrypted-notes clients rather than headline features — frequent small releases with fast hotfix turnaround when regressions surface. The attachment-upload bug appearing on two platforms suggests a shared sync/upload path the team patched quickly.
Expect the v3.3.x point-release stream to continue at this pace, with cross-platform parity and prompt hotfixes as the operating norm; larger feature work isn't visible from these version-only entries.
