The Vibe Plugin Family

One coordinated family of Claude Code plugins — planning, iteration, docs, tests, security, research authoring — installed independently, composed when present. Every plugin follows the same Apache-licensed playbook: self-repair, self-teach, self-evolve, so the tenth run beats the first. 14 plugins, one spine.

Celestia 3

An AI technomancer that reads the actual sky. The Swiss Ephemeris engine was rebuilt to astronomical precision — not the second-rate math most astrology apps ship — so every chart is observatory-accurate. Converse with the Athanor, an AI oracle grounded in your real natal chart, across the Natal Compass, Aura Cam, Arithmancy, Tarot, Rituals, Chronos forecasts, Celebrity Match, Synastry, and the Grimoire.

Sanduhr für Claude

Native desktop widget that shows how fast you're burning through your Claude.ai usage, so you can pace yourself instead of finding out you're out of tokens at 11pm. Burn-rate projection, pace markers, sparkline trends, five hand-tuned glass themes — plus an AI-agent theme prompt that turns a reference image into a drop-in JSON theme. The v3.1 widget overhaul rebuilt the chrome: a compact mode that collapses to the busiest tier, a hover-lift bottom icon strip with a theme flyout, a taskbar button that tracks pin state, a native rounded close button, and a range-normalized sparkline that reads even at low usage. Free on the Microsoft Store with real Win11 Mica glass, Apple-notarized for Mac with Sparkle auto-updates, single-file Python for everyone else. No telemetry — the only network call is to claude.ai with your own cookie.

SnapSnip

Automatically renames full-window snips based on metadata. Reads the active app and window title at capture time, writes a context-rich filename, and embeds structured XMP — turns 'Screenshot 2026-04-29 142301.png' into 'Outlook — Q3 forecast — 2026-04-29 142301.png'. Three on-device redaction presets (Strict / Balanced / Permissive). Privacy by default — no network calls.

RORORO

Multi-launcher for Windows — run multiple Roblox clients side by side, each signed in as a different saved account. Native .NET 10 / WPF, DPAPI-encrypted account vault tied to your Windows user, embedded WebView2 login so your password never touches the app process. System-tray UX with state-coloured ring, per-game launch routing, Velopack auto-update. Now at v1.8: a hardened plugin host — sideload-only, https-only installs, named-pipe IPC with per-capability consent — plus tray-residence recovery (clears a hidden Roblox holding the multi-instance lock, one click from the tray), Limited-account detection, idle-awareness that warns before Roblox's AFK kick, and a signed roblox-compat feed published on every release. Mac-native sibling, and a three-plugin family: Ur Task (portable, window-aware macros), Ur OCR (screen triggers that fire keybinds or Ur Task macros), and Ur AFK (one-tap keep-alive). Free on the Microsoft Store. Independent third-party tool — not affiliated with Roblox Corporation.

626 Mod Launcher

A reversible, atomic mod toggler for PC games — Bethesda, Unreal, FromSoft, BepInEx, Stardew SMAPI, and more. Disabling a mod moves its files to a holding folder instead of deleting them, so every toggle is reversible and every state change writes atomically — lose power mid-toggle and your library survives. Drag a zip onto the window and it identifies the mod, fills in the real name, author, and source link, then installs it where the loader actually expects. Free on the Microsoft Store as the signed sealed-core build (no SmartScreen warning); the GitHub build adds Nexus integration. No ads, no telemetry, no account.

Conundrum by Este

The 626 Labs merch shop — streetwear-grade prints designed by an AI pipeline and sold print-on-demand on Etsy. Gemini generates the art (always textless — type is composited after, so the lettering is real), a QA pass filters the AI slop, classical CV cuts the backgrounds, and one base artwork fans out into a full variant matrix before anything ships. Human approval gates every publish. Socks, joggers, totes, hats.

626 POD Pipeline

The open-source engine behind Conundrum by Este: a Python script library that takes a concept to a live Etsy listing in nine stages. Gemini art generation, an AI-slop QA gate, classical-CV background removal, PIL type compositing, and a variant matrix that fans one artwork into a full product line before Printify upload and Etsy publish. No app server, no build step, a JSON-backed catalog — and a human go gates every publish.

02 · The founding

626 Labs builds exact-fit software.

I build tools, because care doesn't always scale.

626 Labs builds exact-fit software. The founding argument is simple: it has never been easier to have the exact tools we need, and too much money has been going to too many companies for tools that only half fit. So we build and maintain our own, at a quality that rivals enterprise software, made to enhance the work people do instead of taking their jobs. We are here to make great products, even if only a handful of people need them. That's ok.

The line the lab was built on belongs to its founder: "I build tools, because care doesn't always scale." It is translation: take the care a person already has and build it into something that keeps working after their attention has to move on.

We hold that use converts skeptics. Not a demo, not a number, not a story: the tool working in someone's hands. The data in our tools is gathered, not assumed. The bar is a well-put-together piece of technology, and the bar is enterprise-grade. The edge of the portfolio is two words: play nice.

So the lab builds for inheritors it has not met. 626 is a phone exchange: the first three digits of the founder's parents' old phone number, digits that stood for years on unpainted buildings as he passed, leaving the neighborhood for school. The pattern has run once before: his father's sound and light company, Stage Productions, is carried on today by each of his siblings. The seven kids from his house will inherit 626 Labs the same way. Even one more is a win.

RoRoRo grew eyes, hands, and a heartbeat

The Roblox multi-launcher you could recommend on camera now has three plugins (perception, action, and a keep-alive), wired together by a consent-gated bridge that never leaves your machine.

A launcher became a platform. Three plugins, one nervous system, and a trust bar that holds at every rung.

The first 626 Labs Day

Today is 6/26/26, the first 626 Day since 626 Labs existed. The whole surface is shipped and live in one window: 14 Claude Code plugins and 6 Microsoft Store apps, one new and two with major updates this week.

The whole surface is shipped and live, and on 6/26 that's allowed to be the whole point.

2026-05-29

Same code, 3x the thinking: what I did with my first 8 hours with Opus 4.8.

I turned on max-orchestration to see what would happen. Eight sessions later the agent had burned three times the tokens and written the same amount of code. The extra went into tests it caught before I saw them, and into a run that stopped answering the wheel once it started.

3.2x the tokens, the same lines of code. The extra went into care, not output, and into a run that stopped answering the wheel.

2026-05-23 · vibe-insights

I complained that /insights wasn't insightful. Seven hours later I had a plugin that beats it.

It grabs insights from every Claude Code building surface you use, walls work from personal, and can even tell you the story of how it got built.

2026-05-23 · vibe-wrap

I said it's Evolve day. I left with a plugin I'd forgotten we'd planned.

I went in to evolve two plugins. The agent cleared the whole backlog, and out came vibe-wrap, a session-wrap plugin I'd forgotten we planned. It shipped anyway.

The plugin whose entire job is making sure you don't have to remember got finished because an earlier session left exactly that kind of trail.

How the lab runs.

Every project above lives inside a purpose-built agent OS — private, not yet open source. The plugins are the lessons it taught us.

Universe The Lab Dashboard — Universe view, every 626 Labs project as a node in a constellation.
Full expansion Trying to gain every view of our apps that we can so we understand them inside and out.
Operations The Lab Dashboard — project list with live health, recent decisions, and autopilot status.

The 626 Labs Dashboard is a private agent OS — Operation Center, decisions log, Architect AI, and Scanner / Voice / Whiteboard inputs — running as one surface across every active project. It watches the work, logs the decisions, and keeps the threads connected when we context-switch between a hotel app, a theater tool, and a plugin release in the same afternoon.

The Dashboard itself isn't open source. The Vibe plugins are — they're the lessons the Dashboard taught us, refactored so any builder on Claude Code gets the same tailwind.

New ideas to old logic.

TypeScript Swift Python Claude Code React 19 Fort Worth, TX

626 Labs builds modern tools for practices that have been running on spreadsheets, paper, and inherited habits for decades — or, in the case of astrology, a few thousand years. The brief is simple: look at a field that everyone assumes is "fine the way it is," and ship the version it should have had all along.

The proof case is Celestia 3. AI joined with tarot, numerology, and astrology in one surface. Partway through the build, we discovered the default Swiss Ephemeris engine drifted at the second-precision level. We didn't ship around it. We repaired the engine ourselves and met the NASA-grade bar. The point isn't the math — it's the posture. When the bar moves mid-build, we move with it.

That posture is what pulled us into the old empires — legacy operations, safety inspections, hotels, cinema exhibition. Off-the-shelf vendors build for the brochure. We build operator-first — the domain expert in the loop, the AI coder on the keyboard — and ship the tool the shift manager actually needed.

The Vibe plugins — Cartographer, Iterate, Insights, Keystone, Doc, Test, Thesis, Engine, Sec, Taker, Wrap, Walk, Prompt, Lingual — are the other half of the work. Vibe coding is the fastest way to turn an idea into running software right now. It's also the easiest way to end up with something that can't survive production. The plugins close that gap: planning, docs, tests, security, all built so a vibe-coded afternoon holds up in front of real users.

We See You at the Movies is the gaming wedge. Trivia and head-to-head card battles are warm-ups for bigger things on deck.

Every 626 Labs app is built like it might be seen by a thousand pairs of eyes, even when it may only ever be seen by one. That's the standard. I've deployed more apps to production than I ever imagined, and the bar keeps going up. Read the whole story.

P/01

Agents read first.

No plugin touches a codebase before it's read the codebase. Context over cleverness — always.

P/02

Operator in the loop.

The shift manager knows what the tool needs. We build with them, not at them. The domain expert stays on the keyboard.

P/03

Built for a thousand eyes.

Enterprise grade even when the app may only ever be seen by one. That's the standard. It keeps the work honest.

Keep the lab running.

Every 626 Labs plugin is MIT-licensed and maintained on nights and weekends. If the Vibe ecosystem is saving you time, GitHub Sponsors is the cleanest way to say thanks — and to keep the next plugin on schedule.
