What is Spectra?
Spectra spins up a standalone Gutenberg block plugin — with a paid tier from day one.
Spectra just launched Spectra Blocks, a standalone Gutenberg-native block plugin, alongside a commercial Spectra Blocks Pro tier on the same day (July 13). Four days later it shipped a 1.0.1 patch adding a version rollback option and fixing the Button block. This is a brand-new v1.0 product line still stabilizing, with a freemium structure already baked in.
What is Kittl?
Kittl goes agentic: design by intent, with the tools you use wired in.
Kittl is a browser-based design tool that has moved aggressively into AI-native creation. Its weekly product-update cadence carries steady craft improvements (brand kits, on-brand generation), but the last two headline releases are directional: an Apps panel that pulls external tools into the canvas, and now an Agentic AI mode that shifts creation from manual prompt-and-parameter tuning toward stating intent and letting the system drive. Kittl is compressing the distance between idea and finished design.
Spectra vs Kittl: editorial side-by-side
Spectra
6.3DESIGN
Spectra spins up a standalone Gutenberg block plugin — with a paid tier from day one.
◆ Current state
Spectra just launched Spectra Blocks, a standalone Gutenberg-native block plugin, alongside a commercial Spectra Blocks Pro tier on the same day (July 13). Four days later it shipped a 1.0.1 patch adding a version rollback option and fixing the Button block. This is a brand-new v1.0 product line still stabilizing, with a freemium structure already baked in.
◆ Where it's heading
The same-day free-plus-Pro launch signals Spectra is treating Blocks as a monetizable product line rather than a side experiment. Expect rapid point releases as early adopters surface issues — the 1.0.1 rollback feature reads as a safety net for shaky updates. The near-term arc is stabilization and filling out the Pro block catalog to justify the paid tier.
◆ Prediction
Next likely move is a steady run of 1.0.x patches plus new Pro-only blocks. With only three releases visible, the pace and ambition beyond early stabilization are still unclear.
Kittl
7.5DESIGN
Kittl goes agentic: design by intent, with the tools you use wired in.
◆ Current state
Kittl is a browser-based design tool that has moved aggressively into AI-native creation. Its weekly product-update cadence carries steady craft improvements (brand kits, on-brand generation), but the last two headline releases are directional: an Apps panel that pulls external tools into the canvas, and now an Agentic AI mode that shifts creation from manual prompt-and-parameter tuning toward stating intent and letting the system drive. Kittl is compressing the distance between idea and finished design.
◆ Where it's heading
The product is consolidating the whole design workflow inside one surface — first by integrating outside tools (Apps), then by automating the decision-making inside creation (Agentic AI). Together they point at Kittl as an AI design environment where the user sets direction and the agent handles model, format, and style choices, with connected services feeding assets and distribution.
◆ Prediction
Expect Kittl to widen the Apps ecosystem and give the agent more reach — chaining multi-step design tasks and acting across the connected apps rather than generating single artifacts.
