A ready-made Logo Maker UI you can fork, run, and customize with the prompt pack below.
What's actually inside
The honest engineer's breakdown — what the Logo Makertemplate does, how it's wired, and where it's opinionated.
The template builds a logo through four steps — pick an icon, set text, choose colors, pick a layout — and shows all four decisions live on the LogoPreviewCanvas. The IconPicker renders a searchable grid of Lucide icons (tree-shaken from lucide-react, so no heavy bundle impact) plus an SVG upload option for custom marks. The TextInput pairs a company name field with a font selector backed by next/font/google, which loads Google Fonts at build time rather than via a runtime API call — this eliminates layout shift and font flash that plague most canvas-based logo tools.
The ColorSchemePanel uses three react-colorful pickers for primary color, secondary color, and background. The LayoutSelector toggles between icon-left-text-right, icon-above-text, text-only, and icon-only compositions. LogoPreviewCanvas renders all of this using HTML5 Canvas drawImage() and fillText() at multiple aspect ratios (square, horizontal, vertical) so users can see how the logo looks across different placement contexts. ExportPanel downloads the result as PNG at 1x, 2x, or 4x resolution, or copies the SVG markup to clipboard.
Honest caveat: this is a compositor, not an AI generator. It can only combine an existing icon with text and color — it cannot generate novel logomarks, abstract shapes, or vector paths. Set this expectation clearly with users who might expect Stable Diffusion-style generation. The canvas also has a known font-loading race condition (see Gotchas) where the first render may show the fallback system font instead of the selected Google Font.

Fork it and get it running
No env vars, no API keys, no backend — this template is 100% client-side. Fork, preview, and publish in under 5 minutes.
Fork the template in V0
Open https://v0.dev/chat/community/BxfohKRtQuk and click the 'Fork' button in the top-right of the chat. V0 copies the template into your own workspace and opens the editor with a Preview panel on the right.
Tip: Sign in to v0.dev first — the free tier is enough to fork and publish.
You should see: The Logo Maker template opens in your V0 workspace with the Preview tab showing the canvas.
Verify the LogoPreviewCanvas updates live
In the Preview tab, type a company name in the TextInput and click any icon in the IconPicker. The LogoPreviewCanvas should update immediately with the selected icon and text. Use the ColorSchemePanel pickers to change the primary color and verify the canvas reflects the change in real time.
Tip: If the canvas appears to show the wrong font, this may be the font-loading race condition — see Gotchas. Refreshing the preview usually fixes it.
You should see: The canvas updates in real time as you type a name and select an icon.
No env vars needed — skip the Vars panel
Open the Vars panel in the V0 sidebar and confirm it is empty. This template is fully client-side — the HTML5 Canvas API and lucide-react run entirely in the browser. You do not need to add NEXT_PUBLIC_ prefixed variables unless you are extending the template with a Supabase backend.
You should see: Vars panel is empty and the template runs without any configuration.
Add custom Google Fonts to the default set
If you want fonts beyond the template's defaults, open the Code tab and find the next/font/google imports in layout.tsx (or wherever font loading is configured). Add new font families using the same import pattern — for example: import { Playfair_Display } from 'next/font/google'. Each added font needs a CSS variable assigned and passed to the font selector options in TextInput.
Tip: next/font loads fonts at build time, not runtime — no API calls or layout shift.
You should see: Custom fonts appear in the TextInput font selector and render on the LogoPreviewCanvas.
Publish to Vercel
Click Share (top-right) → Publish tab → 'Publish to Production'. V0 deploys to Vercel in 30–60 seconds and returns a live URL. Open the URL on your phone too — the ExportPanel's PNG download should work on mobile browsers.
You should see: A live Vercel URL is returned; the logo maker is publicly accessible and functional.
Optional: connect to GitHub for version control
Open the Git panel → Connect → enter a repo name → V0 creates branch v0/main-{hash} and auto-commits all files. Open the GitHub pull request and merge to main. This is useful if you plan to continue iterating on the template or embed it into a larger application.
You should see: GitHub repo created with logo maker code and first PR merged to main.
The prompt pack
Copy-paste these straight into v0's chat to customize the Logo Makertemplate. Each one names this template's own components — no generic filler.
Add 10 popular Google Fonts to the font selector
Expands the font selection to 10 popular Google Fonts, all loaded at build time via next/font with no layout shift or runtime API calls.
Import Inter, Poppins, Roboto, Playfair Display, Montserrat, Lato, Oswald, Raleway, Merriweather, and Space Grotesk from next/font/google in layout.tsx. Assign each a CSS variable (e.g., --font-poppins). In the TextInput font family dropdown, add all 10 as options with their CSS variable name. When a font is selected, apply the corresponding CSS variable to the LogoPreviewCanvas canvas fillText() font string so the preview updates immediately. Show a live miniature preview of each font option in the dropdown using the font itself.
Add a gradient background option to ColorSchemePanel
Lets users add gradient backgrounds to their logo — a common request for modern SaaS branding.
Add a toggle button in ColorSchemePanel that switches the background from a solid color fill to a linear gradient. When gradient mode is active, show two react-colorful pickers (gradient start and gradient stop) and an angle slider (0° to 360°). In LogoPreviewCanvas, update the canvas context fill to use ctx.createLinearGradient() with the angle converted to x1,y1,x2,y2 coordinates using trigonometry (x2 = Math.cos(angle * Math.PI/180), y2 = Math.sin(angle * Math.PI/180)). Apply the gradient as the canvas background before drawing the icon and text layers.
Add SVG icon upload for custom logo marks
Lets users bring their own SVG icon or existing logo mark into the compositor — useful for brand refinement rather than starting from scratch.
Add a file input in IconPicker that accepts SVG files (accept="image/svg+xml"). When a file is selected, read it with FileReader.readAsText() and convert to a data URL using btoa() on the SVG string. Create an Image element from the data URL and draw it on LogoPreviewCanvas using ctx.drawImage() scaled to match the selected layout's icon size proportions. Store the uploaded SVG data URL in component state alongside the Lucide icon selection so switching between the two is seamless. Show the custom upload as a special entry at the top of the IconPicker grid.
Add a brand kit system with save/load
Lets users save and switch between multiple brand kit variations — ideal for agencies testing options for a client.
Create a BrandKits panel (a shadcn Tabs panel adjacent to ColorSchemePanel) that stores up to 5 named brand kits in localStorage. Each kit saves the selected Lucide icon name, font family, primary/secondary/background colors, and layout mode as a JSON object. Add Save Kit and Load Kit buttons; display saved kits as colored swatches showing the kit's primary color. When a swatch is clicked, restore all kit settings to the corresponding controls and immediately re-render the LogoPreviewCanvas. Wrap all localStorage reads in useEffect with [] deps — never read localStorage directly in the component body to avoid Next.js SSR errors.
Save logos to Supabase Storage and generate shareable links
Persists generated logos to Supabase with shareable permalink URLs — the foundation for a logo generator SaaS.
Create a Supabase Storage bucket called 'logos' with public read access enabled. Add a Supabase client using NEXT_PUBLIC_SUPABASE_URL and NEXT_PUBLIC_SUPABASE_ANON_KEY from the Vars panel. On ExportPanel download click, additionally convert the LogoPreviewCanvas to a PNG Blob using canvas.toBlob(), upload it to the 'logos' bucket with a unique UUID filename, and get the public URL. Save the public URL plus metadata (font family, primary color hex, secondary color hex, icon name, layout mode) to a `logos` table in Supabase (columns: id uuid, font text, primary_color text, secondary_color text, icon_name text, layout text, image_url text, created_at timestamptz). Generate a shareable /logo/[id] route in app/logo/[id]/page.tsx that fetches the record and renders the image_url in a preview.
Gotchas when you extend it
The failures people actually hit when they push this template past its defaults — and the exact fix for each.
LogoPreviewCanvas renders the fallback system font instead of the selected Google Font on first loadWhy: next/font/google loads fonts asynchronously at build time, but the browser still needs to register the font before the first paint. If the LogoPreviewCanvas useEffect fires and calls ctx.fillText() before the font is registered in document.fonts, the browser falls back to the system font.
Fix: Wrap the canvas render function inside document.fonts.ready.then(() => renderCanvas()) to defer the canvas paint until all loaded fonts are confirmed available. Add this inside the LogoPreviewCanvas useEffect that depends on the fontFamily state.
In the LogoPreviewCanvas useEffect, wrap the entire canvas render function in document.fonts.ready.then(() => { /* canvas draw calls here */ }) so fonts are guaranteed loaded before any ctx.fillText() call fires.ReferenceError: localStorage is not defined when loading saved brand kitsWhy: If the BrandKits component calls localStorage.getItem() directly in the component body or in useState initializer, Next.js SSR executes that code on the server where localStorage does not exist.
Fix: Move all localStorage.getItem calls into a useEffect with an empty dependency array. Initialize brand kit state as null or an empty array and hydrate it inside the effect after the component mounts in the browser.
Move the brand kit localStorage load into a useEffect with [] deps in the BrandKits component. Initialize kit state as an empty array and set it inside the effect: useEffect(() => { const kits = localStorage.getItem('brandKits'); if (kits) setKits(JSON.parse(kits)); }, []);PNG export is blurry on retina displaysWhy: The LogoPreviewCanvas HTML element's CSS size is set in CSS pixels, but on retina screens each CSS pixel maps to 2 or 3 physical pixels. The canvas internal resolution defaults to the CSS size, producing a low-resolution PNG that looks blurry when viewed at full size.
Fix: Before drawing, multiply canvas.width and canvas.height by window.devicePixelRatio. Call ctx.scale(dpr, dpr) to scale all subsequent drawing operations, then draw the logo at the physical resolution. The download will be sharp on all screens.
Add devicePixelRatio scaling to the LogoPreviewCanvas export function: const dpr = window.devicePixelRatio || 1; canvas.width = displayWidth * dpr; canvas.height = displayHeight * dpr; ctx.scale(dpr, dpr); before any draw calls. This produces a retina-quality PNG.
The component at https://ui.shadcn.com/r/styles/new-york-v4/color-picker.json was not foundWhy: shadcn does not include a color-picker in its base registry. V0 may reference it when generating ColorSchemePanel, causing a build error on the missing component import.
Fix: Replace the missing import with react-colorful's HexColorPicker, which is already listed in the template's stack and has an identical two-prop API (color, onChange).
Replace the missing shadcn color-picker with react-colorful HexColorPicker in ColorSchemePanel: import { HexColorPicker } from 'react-colorful'; then use <HexColorPicker color={color} onChange={setColor} /> for each of the three color inputs.Template vs. custom — the honest call
A forked template gets you far, fast. Here's where it holds up, and where you'll outgrow it.
The template is enough when
- You need a branded quick-compose tool for SaaS onboarding where users create a team logo on signup.
- The logo use case is constrained — icon + text + color is enough and your users don't need bezier editing.
- You need it shipped this week with no design budget.
- You're building a freemium tool and plan to gate premium export formats (vector, HD) behind a Stripe paywall later.
Go custom when
- You need vector editing with bezier paths and anchor point control — this template is canvas-only, not SVG-editable.
- You need AI-generated logo concepts from Stable Diffusion or DALL-E as a starting point.
- You need a full brand guidelines system with typography scale, spacing tokens, and multi-page export.
- You need batch logo generation for multiple clients or product lines from a spreadsheet.
RapidDev can wire this logo maker to an AI generation backend, Supabase asset storage, and a Stripe subscription — turning the v0 prototype into a monetizable SaaS tool.
Frequently asked questions
Is the Logo Maker v0 template free to use?
Yes. It is a free V0 community template. lucide-react, react-colorful, shadcn/ui, and next/font are all MIT-licensed or ISC-licensed. There are no runtime costs for the base client-side composer.
Can I use logos created with this template commercially?
Yes for the template itself — you own the output. However, if you use Lucide icons as your logo mark, check Lucide's MIT license terms. MIT allows commercial use, but if you plan to trademark the logo, consult a trademark attorney about using an open-source icon as a distinctive mark.
Why does my fork show the wrong font on the LogoPreviewCanvas?
This is a font-loading race condition. next/font loads fonts asynchronously, and if the canvas draws before the font is registered in document.fonts, the browser falls back to the system font. The fix is to wrap the canvas render in document.fonts.ready.then(() => renderCanvas()). See the Gotchas section for the exact prompt to paste into V0.
Can I use this to generate AI logo concepts?
Not out of the box — this template is a compositor (icon + text + color), not an AI generator. It produces deterministic output from your selections. To add AI generation, you would need to integrate a Stable Diffusion API or DALL-E as a separate step, which is a custom extension covered by the Supabase advanced prompt as a starting point.
How do I add my company's existing icon instead of a Lucide icon?
Use the SVG icon upload prompt from the prompt pack above. The medium-difficulty prompt adds a file input to IconPicker that accepts SVG files and draws them on the LogoPreviewCanvas alongside the text — paste it into V0 chat and it adds the feature in one step.
Why is my exported PNG blurry on a retina MacBook?
The canvas internal resolution defaults to CSS pixels, which are half the physical pixels on retina screens. Apply devicePixelRatio scaling (see Gotchas) to render at the full physical resolution. The PNG export prompt in the pack also includes this fix.
Can RapidDev turn this logo maker into a full SaaS product?
Yes — RapidDev commonly extends v0 prototypes like this into monetizable tools. Typical additions are Supabase Storage for logo persistence, Stripe subscription gating for vector export, AI generation via an external API, and Clerk user accounts. Reach out for a build estimate.
Outgrowing the template?
RapidDev turns v0 prototypes into production apps — real auth, database, and payments — at $13K–$25K.
