What changed on 3DLogo.io
User-facing changes, newest first, with the page each one lives on. Plan limits and credit amounts quoted here were true on the date shown; the pricing page is always current.
The MCP server speaks the current protocol, shows previews inline, and signs assistants in the modern way
The connector now serves the 2026-07-28 revision of the Model Context Protocol on the same URL as the previous one, so newer clients such as Claude Code get the stateless, cache-hinted protocol while today's ChatGPT, Claude, Cursor and VS Code keep working unchanged. Hosts that render MCP Apps get an inline card for previews, share links, example looks and generated meshes, with an interactive 3D viewer for the meshes. Assistants that publish a client metadata document (Claude, Claude Code, ChatGPT, Codex, VS Code) register through it instead of dynamic registration, and the consent screen names the host that published it. Renaming, publishing and restyling a saved project are now one update_project tool.
Connector tokens for hosts that cannot sign in
Workflow tools and the model vendors' API-side MCP clients cannot complete an OAuth sign-in, so Account now mints connector tokens: pick a name, the scopes and an expiry, copy the token once, and send it as a bearer header to the MCP server. Each token acts as you within its scopes, shows when it was last used, and can be revoked at any time.
The MCP server shows, shares and restyles, and no longer asks you to sign in first
An assistant connected to the MCP server can now show a picture of a saved design or a generated mesh, hand back a share link with the embed snippet and a poster image, restyle a saved logo or coin (material, room, motion, text; coins their look and colours), copy one for a variant, and browse the example looks with a render each. Connecting no longer starts with a sign-in: the catalogue and studio-link tools work at once, and the first account tool asks you to connect. Every tool now declares the shape of what it returns, the consent screen names the three connector scopes, and a machine-readable server card is published for directories.
Light, dark, or follow the device
The header has a theme control. Pick Light or Dark and every page keeps it in this browser, across tabs; pick System and the site follows your device as it did before. The choice is applied before the page paints, so nothing flashes, and native controls, scrollbars and the browser bar follow it. On a phone the same three options sit in the menu.
Feedback from the studios too
The editor, the coin studio and Generate carry a Feedback entry in the bar beside the support address, and a shared design has one in its footer beside Report. Same dialog, same reasons; the note records the page it came from. Nothing floats over the viewport.
Feedback from any page
A Feedback control sits at the bottom-right of marketing and account pages. Pick a reason, add a note if you want; closing it sends nothing. Studios keep the support address in the bar. The note includes the page you were on.
Cancel asks why, and /report covers billing too
Leaving Stripe checkout, or cancelling a plan from Account, now asks an optional one-tap reason so we can tell price from product from a card that failed. Skip is always there; cancel still confirms on Stripe. The report form also takes billing problems, unauthorized charges, and abuse that is not a share link.
Pages that describe a 3D logo now show one, and every page got lighter
Forty-one pages described something visual and showed nothing: the style pages named a material without rendering it, the surface pages explained where a logo goes without showing it there, and the two source pages are entirely about what the input looks like. All but five now carry a render of their own subject, and the animated page plays the real five-second loop rather than a still of one. The five without are the legal and contact pages, where a picture would be decoration. Every page also got lighter: the site logo in the header was a 116 KB file drawn at 32 pixels on all 88 pages, the press kit rendered its full-resolution downloads as its own thumbnails, and the converter pages shipped a sample image eight times larger than the copy already on the site.
Terms cleaned up, and a page for logos in an email signature
The Terms answered refunds in two places and the two disagreed, one of them pointing at a policy document that did not exist. There is now a single clause, and the pricing page answers the question directly. A new page covers putting a 3D logo in an email signature: transparent PNG at twice the display size, a solid finish rather than chrome, and why a good share of recipients will never load the image.
A guide to sharing and embedding a 3D logo
Sharing and embedding were in the product and documented nowhere. A new page covers creating a share link, what the embed snippet contains, the four switches you can set before copying it, which platforms unfurl a bare link through oEmbed, how long a guest link lasts, and what embedding will not do. Topic clusters are also now expressed in the structured data, so each hub lists the pages under it.
A main landmark on every page, and the specs behind the measurements
Thirty-nine pages, including every studio, converter and viewer, had no main landmark, which left the skip-to-content link pointing at nothing in particular and gave screen readers no primary region to jump to. There is now exactly one on every page, defined once. The measurement page also cites the glTF, STL, OBJ and PLY specifications that define what each format can carry, so its claims can be checked rather than trusted.
Readable by agents: Markdown versions, machine-readable pricing, a contact page
Every guide page now serves a clean Markdown version at the same URL to clients that ask for it, and at a /md address for those that do not negotiate. Pricing is published as a machine-readable file at /pricing.md, the whole guide is available in one file at /llms-full.txt, and there is a proper contact page. A broken MCP resource was also fixed: its URI scheme started with a digit, which is invalid, so no standards-compliant client could read it.
The coin studio gets a guide: challenge coins, blanks, and relief
Two pages explain the coin studio rather than only running it. One covers designing a challenge coin, what makes a struck mark read well, and the other jobs the same three blanks cover. The other compares the reeded, milled, and smooth blanks, explains striking one metal into another, how deep a relief should go, and the four things the studio will not do, including that both faces carry the same mark.
Every material in one place, and the measurement data as a download
A new page lists all 68 material presets across 14 families, what each family is for, which need Pro, and what metalness and roughness actually change. It also answers the surface textures, the eight lighting environments, and why the font list is short. The measurement data behind the conversion and geometry-cost pages is now downloadable as JSON.
Measured: converting a 3D file does not change the shape
Every conversion was run and then read back, and the surface came out identical: the same triangle count and the same surface area on a 498,734-triangle mesh, with no coordinate truncation in any format. So a 3D conversion is not lossy the way re-saving a JPEG is; what you lose is the colour, materials and scene structure the target cannot carry. A new page also covers 3D logos for streaming and gaming: Twitch avatar, panels, offline banner, and alert stings.
Answers where the questions were: pricing, privacy, and when not to use a 3D logo
Pricing now answers what it costs, what Pro includes, how credits work, and how to cancel, as questions rather than a billing table. The privacy policy carries the same facts in plain language. A new guide page covers where a 3D logo is the wrong choice: favicons, embroidery, engraving, single-colour print, and small sizes. Exporting now publishes measured geometry cost, and every glossary term has its own link.
Measured: what a 3D conversion actually keeps
A new page publishes original measurements rather than claims. The same loaders and exporters the browser converter runs were run headlessly over a controlled reference scene and real meshes, and the attributes were read back out of the written bytes. GLB and glTF keep everything; OBJ keeps separate objects and material names but drops vertex colour; STL keeps only triangles; PLY keeps vertex colour but merges the scene. A press and brand kit page publishes the approved description in three lengths.
Generate guide: image to 3D, text to 3D, and mesh density
Three pages explain the Generate studio rather than only running it. One covers which photos make a good mesh and what the GLB contains, one covers writing a prompt and how long it can be at each density, and one compares Fast, Standard, High, and Ultra on face ceiling, wait, and credits, including how many generates a monthly or yearly allowance covers.
Guide: starting files, exporting, glossary, license, and troubleshooting
Six new pages close the gaps in the 3D logo guide. Two explain how a mark becomes 3D depending on what you start from: an SVG extrudes its paths directly, while a PNG or JPEG is traced in the browser first. The rest answer what to export and at what size, what every term in the editor means, who owns the result and whether it can be used commercially, and what to do when an upload is refused or a render looks wrong.
Connector: 3D logos from an uploaded image
An AI assistant can now hand the editor an existing logo image, not only a wordmark: an attached file, a public image URL, or a one-shot upload URL for files on the user's machine. The image is stored for seven days and traced into 3D in the browser when the editor link opens; signed-in connections can save it straight to Projects.
Guide pages show the finishes; converter routes grouped by source file
The 3D logo guide shows the chrome, gold, and glass renders on its style grid, the coin look pages carry the coin render, the pricing page opens with one sentence, and the converter hub lists its 25 routes grouped by the file you have. AI search crawlers (ChatGPT search, Perplexity, Claude) can now fetch every page.
Head-to-head comparison pages
Six pages under /3d-logo/vs set 3DLogo.io beside Canva, Sloyd, Meshy, Looka, Wix Logo Maker, and 3DLogoLab on the same dimensions, quoting each product's own page and dated. The 3DLogoLab page states that the two sites are unaffiliated.
Knowledge pages: what a 3D logo is, styles, use cases, kinds of makers, viewers
New pages under /3d-logo explain the six styles, what an app icon, a social clip, a website hero, and print need from a 3D logo, and how browser extruders differ from template makers and AI generators. /3d-viewer lists which viewer opens which file. An About page states what 3DLogo.io is and is not.
Generate tiers: Fast is free; Standard, High, and Ultra on Pro
Fast returns a textured draft for 30 credits and is the free rung, one a month per account. Standard (68), High (120, PBR, extra views included), and Ultra (203, 1M faces) run on Pro credits. Provider engines are not named in the product.
Share links follow the design
Reopening Share on a restyled design updates the existing link in place, so a posted URL always shows the current version. Remix applies the shared look in the studio. The share page renders the design as authored, still or moving, and social clips frame the mark at half the frame instead of edge to edge.
Free tier: one Fast generate a month, per account and per network
Signup welcome credits are off. Free accounts get one Fast generate a month; the same allowance applies per network address so one household or office shares it. Failed jobs still return their credits.
Sharing and embeds
Every design can be shared at /s/{link} with a poster and a short clip, embedded with an iframe at /e/{link}, and posted to X, Threads, Bluesky, LinkedIn, Reddit, Pinterest, WhatsApp, Telegram, Facebook, Instagram, TikTok, Shorts, Discord, and Xiaohongshu. Guests get a 14-day link; signing in keeps it. oEmbed is supported, and a report form covers abuse.
Sign-in protection
Cloudflare Turnstile guards signup and sign-in, sessions were hardened end to end, and free-credit grants are rate-limited per address.
MCP server, agent skill, and studio deep links
AI assistants can open the editor or the coin studio with text, material, look, colours, and motion set, list materials and plans, read and publish saved projects, and run Generate on the account's credits. Listed in the official MCP registry.
Save and share from every studio
Logos, coins, and Generate results save as projects and share from the same panel; the free export watermark is on every free file, not only video.
480p MP4 is free; HD video is Pro
A 5-second 480p MP4 loop exports on Free with a small 3dlogo.io mark. Pro exports 720p and 1080p with nothing on the clip.
3D coin generator aligned with the live reference
One metal in two colours (blank and relief), reeded, milled, and smooth blanks, a raised border so the coin reads as struck, and motion presets with previews.
Material catalogue audit
Every preset was matched against its reference render, and finishes people reach for on 3D type were added: brushed and machined metals, precious metals, holographic, glass variants, gradients, plastics, clay, neon, velvet, carbon, wood, and stone.
Studios, tools, and header
The logo editor, the coin studio, Generate, the 3D converter, and the viewers share one header that matches how people move between them.
