Pencil2D vs Oxygen
A side-by-side editorial comparison of Pencil2D and Oxygen — release velocity, themes, recent moves, and the top alternatives to consider.
Pencil2D vs Oxygen: at a glance
What is Pencil2D?
Pencil2D's 0.7.1 candidates are mostly about not losing the user's work
Two release candidates for 0.7.1, twenty months apart, plus the earlier 0.7.0 candidate. The substantive changes are data-integrity fixes — a ClipboardManager memory leak, frame data loss when copying bitmap keyframes, project recovery dialog improvements, backups on polyline completion — alongside macOS codesigning and notarization and a reworked toolbox layout that reflows into rows or a single column.
What is Oxygen?
Oxygen 6.2 beta adds an MCP server, making the WordPress page builder AI-agent controllable
Oxygen is deep in the 6.2 beta cycle (now at Beta 8), with the headlining feature being an MCP Server — meaning AI agents can directly drive Oxygen's page builder via the Model Context Protocol. Alongside the beta track, stable releases 6.1.2 and 6.1.3 addressed a security issue in the Design Library import flow and a regression fix. The 4.9.8 RC 1 branch keeps the legacy Classic version compatible with WooCommerce 11.

Pencil2D's 0.7.1 candidates are mostly about not losing the user's work
◆ Current state
Two release candidates for 0.7.1, twenty months apart, plus the earlier 0.7.0 candidate. The substantive changes are data-integrity fixes — a ClipboardManager memory leak, frame data loss when copying bitmap keyframes, project recovery dialog improvements, backups on polyline completion — alongside macOS codesigning and notarization and a reworked toolbox layout that reflows into rows or a single column.
◆ Where it's heading
For a hand-drawn animation tool the recurring subject is protecting in-progress work, and that is where these candidates spend their effort. The platform work sits alongside it: signed and notarized macOS builds and an updated Qt6 runner are the cost of shipping a desktop app users can install without warnings.
◆ Prediction
A general 0.7.1 release is the natural next step once the candidate cycle settles, though the twenty-month gap between candidates makes timing hard to call.

◆ Current state
Oxygen is deep in the 6.2 beta cycle (now at Beta 8), with the headlining feature being an MCP Server — meaning AI agents can directly drive Oxygen's page builder via the Model Context Protocol. Alongside the beta track, stable releases 6.1.2 and 6.1.3 addressed a security issue in the Design Library import flow and a regression fix. The 4.9.8 RC 1 branch keeps the legacy Classic version compatible with WooCommerce 11.
◆ Where it's heading
The MCP Server is the most directional move Oxygen has made in recent history. Once GA, it puts Oxygen in the category of AI-agentic design tools — a page builder that an LLM can compose, edit, or debug programmatically. Beta 3's UI localization signals that international market expansion is happening in the same release, broadening the addressable user base alongside the AI capability.
◆ Prediction
Oxygen 6.2 GA is the immediate next move; the question is whether MCP integration depth expands post-launch to cover template generation, responsive breakpoints, and component discovery — the scenarios where AI-driven page building would actually save time.
