What is Penpot?
Penpot chases Figma parity while betting on self-host and AI-agent access
Penpot is the open-source, deployment-agnostic design and prototyping tool, and its releases run on two tracks: steady Figma feature parity (background blur, design tokens, export formats) and infrastructure that sets it apart — self-hosting, an MCP server for AI assistants, and a WebGL rendering path. Development is fast and community-heavy, with each numbered release carrying dozens of enhancements and fixes.
What is Spectra?
Spectra shipped a brand-new block plugin and a paid tier for it on the same afternoon.
Spectra launched Spectra Blocks, a ground-up Gutenberg block plugin, on 13 July 2026, with Spectra Blocks Pro arriving ninety seconds later in the same changelog. The month since has been a tight 1.0.x cadence: version rollback, automatic theme colour sync, and fixes across both the free and Pro builds. Two releases landed on 7 August alone, one for each edition.

Penpot chases Figma parity while betting on self-host and AI-agent access
◆ Current state
Penpot is the open-source, deployment-agnostic design and prototyping tool, and its releases run on two tracks: steady Figma feature parity (background blur, design tokens, export formats) and infrastructure that sets it apart — self-hosting, an MCP server for AI assistants, and a WebGL rendering path. Development is fast and community-heavy, with each numbered release carrying dozens of enhancements and fixes.
◆ Where it's heading
Two bets run in parallel. One is closing the remaining gap with Figma feature-by-feature; the other leans into what a hosted competitor can't easily copy — private or on-prem deployment and agent-readable design files via MCP. The token-system depth and WebGL work suggest Penpot wants to be both a credible daily design tool and the default for teams that need control over where their design data lives.
◆ Prediction
Expect the parity grind to continue release-over-release, with the WebGL renderer maturing out of beta and the MCP and self-host story pushed harder as the differentiator against hosted rivals.
Spectra
6.3DESIGN
Spectra shipped a brand-new block plugin and a paid tier for it on the same afternoon.
◆ Current state
Spectra launched Spectra Blocks, a ground-up Gutenberg block plugin, on 13 July 2026, with Spectra Blocks Pro arriving ninety seconds later in the same changelog. The month since has been a tight 1.0.x cadence: version rollback, automatic theme colour sync, and fixes across both the free and Pro builds. Two releases landed on 7 August alone, one for each edition.
◆ Where it's heading
This is an early-life product being hardened in public, and the choices reveal the audience. Version rollback is a safety net for agencies who update client sites and need an exit; theme colour sync is about blocks inheriting the site palette instead of fighting it. Both point at Spectra Blocks being positioned as infrastructure a professional builds on rather than a set of decorative blocks.
◆ Prediction
Expect the 1.0.x fix cadence to continue for several more weeks before the block library itself starts expanding, with Pro staying a release or two behind the free edition. The changelog bodies are truncated in this feed, so which specific blocks ship next is not visible from here.
