Start with task duration
A ten-minute launch demo can tolerate more spectacle than a full day of implementation work.

Codex themes by workflow
Codex themes for the way you build.
A founder demo, an eight-hour debugging session, and a livestream do not need the same workspace. These guides start with the job to be done, then work backward to contrast, artwork, branding, and delivery choices.
How to use this library
Choose with the finished workspace in mind.
Persona pages should answer operational questions, not simply attach an audience name to a generic theme. Each guide identifies what viewers notice, what the operator must read, and which visual choices can become a liability during real work.
The outcome is a narrower brief: which assets to prepare, how much brand presence is appropriate, which preview states to inspect, and when a free template is a better starting point than a custom pack.
Browse every guide
8 specific starting points, each with its own tradeoffs.
01 · Developers
Codex themes built for long development sessions.
A developer theme earns its place after the novelty wears off. It should make the active task obvious, keep code and diffs readable, and leave enough visual identity to make the workspace feel personal through a full day of building.
Open guide →02 · StartupsA startup Codex theme that looks ready to ship.
For a startup, the theme often appears in more places than the founder expects: launch videos, support clips, investor demos, workshops, and screenshots. It should feel recognizably yours without turning the development surface into a marketing banner.
Open guide →03 · BrandsA branded Codex theme with a lighter touch.
A branded workspace should feel designed by the company, not wrapped in an advertisement. The useful brief translates brand color, atmosphere, and graphic language into surfaces that still respect code, controls, status colors, and long-session comfort.
Open guide →04 · StreamersA Codex theme that reads clearly on stream.
A streaming theme serves two people at once: the builder operating Codex and the viewer watching a compressed, possibly scaled video feed. Strong silhouettes and controlled contrast survive that journey better than tiny detail or elaborate generated scenery.
Open guide →05 · Deep focusA deep-focus Codex theme that knows when to disappear.
Deep focus does not require a visually empty workspace. It requires predictable attention: the active task is strongest, supporting controls are available without calling out, and the background creates atmosphere only around the edges.
Open guide →06 · DesignersA Codex theme for designers who notice the details.
Designers can push a theme beyond generic dark mode, but the best result still behaves like a product surface. It needs a coherent material idea, intentional spacing, accessible interaction states, and artwork that survives real window geometry.
Open guide →07 · TeamsA shared Codex theme without a one-size-fits-all rule.
A team theme is most useful as a common starting point, not a visual mandate. Shared colors and artwork can make workshops and recordings coherent while individual light, dark, and reduced-art variants preserve comfort and accessibility.
Open guide →08 · AI buildersA Codex theme for the AI-native build loop.
AI-native building involves rapid context changes: prompting, reading plans, reviewing code, scanning tool output, and moving between tasks. A useful theme reinforces those transitions without inventing a futuristic dashboard that competes with the actual product state.
Open guide →Shared principles
Separate operator and audience
Streamers and presenters need a scene that reads on video without making controls harder for the person driving.
Use branding as a system
For teams, keep approved colors and logos separate from generated art so they remain legible and replaceable.
Choose the smallest useful pack
Begin with a verified gallery theme when it solves the workflow; create and publish a new pack only when the brief truly requires it.
Practical answers
Questions worth answering before you choose.
Should every team member use the same Codex theme?
Not necessarily. Share a common token and artwork baseline, then allow light or dark variants for room conditions and accessibility. Consistency should help recognition without forcing one luminance level on everyone.
Is a branded Codex theme useful outside marketing?
It can make workshops, demos, onboarding recordings, and shared development environments recognizable. For private day-to-day work, restrained branding usually performs better than a prominent campaign treatment.
Can I preview a workflow theme without an account?
Yes. The builder can generate a prompt and preview home, task, and narrow layouts in the browser. Paid upload and packaging remain separate, and free themes can be downloaded without an account.
Build the rest of the theme brief.
Move between visual style, workflow, and platform constraints, then use the builder to generate image guidance and preview the result.
