Muse Community Roundup: What the First 228 Builds Show

The first 228 builds in this catalog show three things: the open-weights Muse Glimmer model drew the most builder attention, connectors became the fastest-growing kind of build once Meta opened the platform on September 18, and the personal agent's most-shared wins are about money. Tools and apps is the biggest category with 88 builds, and more than half of everything was filed after the Muse agent launched on September 8.

The counts below come straight from the catalog's seed data as of September 25, 2026. They measure what people shared publicly and what we filed, not total usage.

Builds by category

Category	Builds
Tools and apps	88
Research and data	52
Agents and browsers	39
Games and real time	18
Content and growth	14
Triage and routing	9
Robotics and devices	4
Trading and markets	4

Tools and apps is large because it collects infrastructure: editor bridges, runtimes, connector templates and platform listings. Research and data is second because Glimmer's release produced a wave of benchmarks. Trading and robotics are thin, which is a gap more than a verdict.

Of the 45 Reddit posts, 31 came from r/MuseAgent and 9 from r/LocalLLaMA. That split mirrors the two audiences: agent users trading errand stories, and local-model users benchmarking Glimmer. Skills (31) is almost entirely connectors and plugins; 21 of them sit in tools and apps.

Which Muse product gets built on most?

Counting by tags, an entry can count toward more than one product:

Product	Tagged builds
Muse Glimmer	63
Muse agent	45
Muse Spark	40
Connectors	40
Muse Code	20

Glimmer leads despite being the least marketed product. It is free, it runs locally, and the local-model community tests everything. The launch week alone produced a pile of hardware reports, from an RTX 4090 fitting 130K context to a Qualcomm board running it at 2.84 tok/s. We collected those in running Glimmer on a consumer GPU.

How the catalog grew week by week

By filing month: 7 builds from April (the original Muse Spark launch), 1 from June, 5 from July, 63 from August and 152 from September. The two spikes line up with releases:

• August 10 to 16: 44 builds in one week, almost all Glimmer. Day-0 support from Ollama, SGLang and transformers, plus Unsloth's fine-tuning notebooks.
• September 8 onward: 125 builds, more than half the catalog, after the Muse agent launched. The busiest single days were September 22 (15 builds), 21 (13) and 24 (11), right around the Amazon block, the payment partnerships and Meta Connect.

Connectors took over after September 18

Before September 18, custom connectors were something Muse wrote for you. Once Meta opened muse.ai/platform, builders started shipping them as products. Meta says it received more than 1,500 applications in under a week (TechCrunch).

The catalog shows the same shift in miniature. Connector builds filed after the platform opened include an HVAC booking connector, a payee-change verifier, a wardrobe stylist, a Slack bridge, an India-focused hub and a catalog of 150 connector skills. One earlier collection, 150 one-paste skills, landed two days before the platform opened. Templates followed: Cloudflare Workers and a multi-target deployable.

What the agent builds are actually about

Among the agent builds, the recurring pattern is errands with a dollar figure attached: an AT&T bill halved, a $250 Delta credit, $113 a month off car insurance, $88.92 in unclaimed property. An outside count agrees: Agents Breakroom sorted about 500 real Muse use cases and found 20% were about money. More in real errands people delegated.

The other agent theme is people poking at the machine itself. Builders exported the agent's filesystem, mapped its on-disk architecture, probed for undocumented device tools and ran Claude Code inside its VM.

Spark builds split between games and skepticism

Muse Spark 1.3 builds fall into two piles. Games: a pirate platformer its author says worked on the first shot, and a Minecraft-style world he says cost 10 cents. And checks on Meta's claims: DataCamp found a net 12% cost increase across three tasks, and MindStudio got "a cube shooting at other cubes." Both are fair; the community is doing the testing Meta's benchmarks cannot.

Muse Code's 20 builds are mostly about using it somewhere else: Zed and JetBrains, VS Code, a desktop app, a remote web terminal, and delegation from Claude Code.

Research builds are doing Meta's homework

Research and data is the second-largest category, and most of it is independent testing. On Spark 1.3 alone the catalog has a CVE rediscovery benchmark (19 of 32 at pass@1), a 105 planted-bug test where max effort fixed 33, a writing benchmark placing it 24th of 87, and a VulcanBench run that found serious issues at lower effort levels. On Glimmer, the tests range from Magic: The Gathering tournaments to a calorie-estimation benchmark. For a summary of the vendor numbers, see Muse Spark benchmarks.

What is missing

Four builds each in trading and robotics. No accessibility builds at all, despite a clear review of VoiceOver gaps. Almost nothing from outside the US, which follows from the launch region. If you have built in one of those gaps, submit it.

Frequently asked questions

How many Muse builds are in the shipwithmuse catalog?

There are 228 builds as of September 25, 2026, across eight categories and seven source types. Tools and apps is the largest category with 88, and X posts are the most common type with 52.

Which Muse product do builders use most?

Muse Glimmer, the open-weights model, is tagged on 63 builds, more than any other product. The Muse agent follows with 45, then Muse Spark and connectors with 40 each.

When did most Muse builds appear?

Most came after the Muse agent launched on September 8, 2026, which accounts for 125 of 228 builds. The other big spike was Glimmer's release week, August 10 to 16, with 44 builds.

What are people doing with the Muse agent?

The recurring uses are money errands like bill negotiations, flight compensation and subscription audits, followed by household admin and experiments that explore the agent's own VM. An outside survey of about 500 use cases found 20% were about money.
