Best new AI agent, design and developer resources: 1 October

1 October's additions lean towards running and securing AI coding agents, plus a big batch of design inspiration and interface components. Pick the group that matches what you're working on today. Features and pricing change, so check each tool's own page before you commit.

Running, watching and configuring your AI coding agents

First up, ccmux. It's a tmux dashboard that tracks every coding agent as idle, working or waiting, so you can jump straight to whichever one needs you.

Using more than one assistant? OpenCastle lets you write your assistant configuration once and use it in each of them. agnix lints files like CLAUDE.md, SKILL.md, hooks and MCP configs before your tools quietly ignore them. JFrog Boost trims noisy command output before it reaches your agent, which helps keep token use down. And Distill gives agents persistent, deduplicated memory without extra LLM calls.

The Pair runs a Mentor and an Executor agent that cross-check each other's code, a handy way to catch mistakes nobody checked. OpenGUI and Dais are desktop-first workspaces. OpenGUI is an open-source coding agent with durable sessions that works with any OpenAI-compatible model endpoint, and Dais manages several agent tasks at once with MCP tools and skills.

Building, testing and securing agent systems

SmythOS Studio is an open-source visual builder for agents. Tracely turns real production failures into regression tests that run in CI. Uber ADR is an open-source security system for enterprise AI agents that runs in production at Uber. Note that its prevention component isn't part of the open-source release.

AFDocs scores how well AI coding agents can read your documentation, and Atomic Mail Agentic gives an agent its own email inbox through a JMAP-based API. Awesome Jev Live is a self-updating, evidence-graded index of the TypeSafe System One ecosystem. vibe-to-ui helps an agent turn a generic AI-generated page into a deliberate design direction. These are built for developers, so start with the one that fits a problem you actually have.

Inspiration for design and type

Design for B2B collects more than 90 B2B websites by industry. SparkBites shows the fonts, colors and tech stack behind more than 270 sites, with DESIGN.md files and an MCP server for AI agents. A1 Gallery lets you filter hand-picked sites by stack, style and color palette. Browsing is free, and a Pro plan adds more saves.

Umanmade showcases digital creative work made by humans across web design, motion, 3D, branding and illustration. Logggos is a logo catalogue you can filter by type, style, color and typography. UNCUT.wtf offers 163 typefaces that are free for commercial use. SearchSystem is a curated archive of design references and tools, with a paid shop sitting next to the free archive.

Giving your interfaces some polish

Paper Shaders gives you zero-dependency canvas shaders for the web, from paper texture and fluted glass to liquid metal. tweakcn is a visual theme editor for shadcn/ui, and Anicon offers more than 500 animated SVG icons you add with one command. DialKit adds a live control panel so you can tune springs, easing and layout as you build. NumberFlow animates numbers smoothly as their values change.

ASCII Magic is a different sort of creative tool. It turns photos and videos into ASCII, pixel art, halftone and more, right in your browser, with no upload or signup.

A few picks for specialists

Myna Recorder is a Windows macro recorder that produces readable, editable scripts, and its free plan covers recording, editing and replay. ReClip is a self-hosted downloader for video and audio, so only save content you have the right to download. Mirobody pulls labs, wearables and genetic files into one self-hosted record. Treat anything it shows as information, not medical advice.

SeaLeap Amazon Skills packages Amazon selling know-how as reusable agent skills, though its documentation is mostly in Chinese. Django ORM Lens finds N+1 queries and risky migrations in Django projects without booting them. OpenDraft drafts research papers with citations checked against scholarly databases. Always verify the content and follow your institution's rules.

Don't add everything at once. Start with one agent workflow, one design resource or one interface experiment. The rest of yesterday's additions are waiting in the full directory.
