poster-design is an open-source design project by palxiao (palxiao/poster-design on GitHub). It has 4,901 GitHub stars and 751 forks, is released under the AGPL-3.0 license, and was last updated on GitHub on 10 September 2026.
Use the hosted demo to evaluate, or self-host the open-source edition for your own design site or internal tool.
Get the source from GitHub.
Run the prepare script, then start the dev server.
Visit the local site, sign in, and create your first poster; the admin backend lives under /admin.
Drag, group, scale, align, and distribute elements freely, with layers, rulers, snap guides, undo/redo, and multi-board support.
Fonts, sizes, colors, spacing, and CSS-based effects such as shadows, outlines, and gradients, plus decorative text compositions.
Free AI image generation and copywriting, and one-click AI background removal (matting) with brush repair/erase — no separate deployment needed.
Parse PSD design files to help recreate designs as editable templates.
Generate QR codes with custom colors, sizes, gradients, and embedded logos.
User registration and saved works, plus admin management of templates, assets, fonts, categories, users, and AI provider configuration (any OpenAI-compatible API).
Clone the project and enter its directory.
git clone https://github.com/palxiao/poster-design.git
cd poster-designRun the project's prepare script as documented in the README.
npm run preparedStart the site and open it in your browser.
npm run serve
# then open http://127.0.0.1:5173/Developer palxiao and contributors; a paid 'Plus' enterprise edition with private deployment and support is offered separately by the same team.
The open-source edition in this repo is free under the AGPL-3.0 license, which includes the full editor, admin backend, and AI capabilities; the AGPL's copyleft terms apply if you distribute modifications.
Core design features do not. AI generation features can be configured in the admin backend with any OpenAI-compatible API (the default points at Zhipu's open platform), which may require your own key.
It offers a similar browser-based, template-driven design experience but is self-hostable and open source, with your data in your own SQLite database — at the cost of running and maintaining the deployment yourself.
Clone the repo, run `npm run prepared` and `npm run serve`, then open http://127.0.0.1:5173/ (admin backend at /admin).
