Mock up gallery wall layouts to scale with your photos before hanging real frames.
u/Individual_Plane5170 · Reddit
I built a free, open-source gallery wall planner because the good ones are paywalled My wife and I were decorating a big wall and couldn't agree on a layout. I wanted to place real frame sizes with our own photos and see it to scale before drilling. Tools exist (GalleryPlanner, Suprtiles…), but the good ones paywall the useful bits or felt heavier than I needed. So I vibe-coded a stripped-down one over a evening.

I built 3 AI video tools into one platform. Would love some honest feedback. I’ve been building Veerframe , a platform with 3 different AI video tools: Generate animated visual graphics from a simple prompt Turn long videos into Shorts, Reels, or TikToks Generate a full video from an idea or your own script, including graphics, stock footage, transitions, and AI or cloned voiceovers I’m at the point where I’d really like feedback from people who haven’t been staring at it for mon

做了个 Codex Desktop 主题预览和切换工具,先调好再安装 最近一直在用 Codex Desktop ,觉得默认界面看久了有点单调,就顺手做了个主题编辑工具,分享一下: [Codex Skin]( https://getcodexskin.com) 可以先在网页里预览主题,调整背景透明度、面板透明度、颜色、模糊和圆角等参数,满意之后再下载并切换到 Codex Desktop 。 目前支持: - 自定义 JPG 、PNG 、WebP 背景 - 在线实时预览主题效果 - 调整透明度、颜色、模糊、圆角 - 预览满意后生成安装命令 - 不喜欢了可以恢复默认外观 目前主要面向 macOS 上的 Codex Desktop ,还是个人项目,功能和兼容性都在继续打磨。 欢迎试试,也想听听大家对主题参数、预览效果和安装流程的反馈。 直接网址: https://getcodexskin.com [轻喷 轻喷,可能还有些 bug

I've been slowly adding some new free tools to Moxie Docs (partly for SEO, partly to illustrate some of our feature sets before any commitment) for some reason this mermaid editor one blew up on Google rankings so I figured I'd share in case people find it useful! We also have ADR, AGENTS.md, LLMs, and a few other free tools.

做了一个视频生成工具,送大家一些积分体验体验 最近做了两个 AI 生成相关的小站,想发出来给大家试试,也顺便收一些真实反馈。 做了几个烂东西,满满的沉淀为现在的样子,实在是太不容易了。 图片站: https://flux3image.pro 视频站: https://flux3video.online 两个站的定位不太一样: Flux 3 Image 主要偏图片工作台,支持文生图、参考图生成、图片编辑、比例和分辨率选择,也接了一些不同风格的图片模型。 Flux 3 Video 主要偏视频生成,支持文本/图片输入生成视频,可以调时长、比例、分辨率、帧率,也有 Fast / Pro 这类模式。 独立 AI image / video workspace ,接第三方模型和自己的账号、积分、任务记录流程。 现在基础功能已经能用了,新用户登录后会有一些 starter credits ,可以先体验,不用一上来付费。具体积分和消耗以站内显示为准,避免我帖子里写死后面配置调整。 我自己知道现在还比较早期,尤其是两个站之间的定位、模型命名、价格解释,还
