Skills (Vercel Labs) alternatives (2026)

Skills (Vercel Labs): MIT skills CLI when you need one installer across harnesses — not Addy/Matt/BMAD content packs and not Skillbox self-host; treat the star spike with caution.

Its Catch: ★32871 in about 37 weeks (~889 a week): judge it on the CLI/ecosystem substance, not the star count.

Below: 8 free or free-tier tools from the same category (agent skills packs), free and open source first, then the closest match by shared tags. Each keeps its own Catch.

  1. 1.video-useVideo-editing skill stack for coding agents

    Free / OSS · OSS/MIT · 29.3k GitHub stars

    VerdictMIT local video-editing skills for coding agents. Keep it when you want inspectable FFmpeg workflows; do not mistake it for a browser agent or a turnkey editor.

    CatchVs HyperFrames and Browser Use: video-use is a video-editing skill stack, not browser automation or a general web-use agent. The useful path needs shell access and FFmpeg, and transcription needs ElevenLabs unless you supply another compatible route; Cloud is optional, but the local setup is not zero-dependency or zero-credential.

  2. 2.CC SwitchMIT desktop All-in-One manager for Claude Code, Codex, OpenCode, and peers

    Free / OSS · OSS/MIT · 146k GitHub stars

    VerdictMIT desktop switchboard when you juggle many coding-agent configs and MCP/skills; skip if you live in one harness with one provider.

    CatchVs editing each harness config by hand or using a single-vendor settings UI: CC Switch is a cross-harness desktop manager, not a coding agent and not an API gateway. Extreme star velocity (~136k aria-label) and a long sponsor/relay block on the README — treat momentum and affiliate banners as noise; verify releases from the GitHub/ccswitch.io path you trust.

  3. 3.InsForgeApache agent-native backend with MCP self-host

    Free / OSS · Freemium · 13.1k GitHub stars

    VerdictApache agent-native backend when coding agents should own DB/auth/storage over MCP — not plain Supabase; cloud Free is capped, Compose is the unlimited OSS path.

    CatchCloud: Free is capped and pauses; Pro (~$20–25/mo) plus separate InsForge Compute and model-gateway usage. Vs Supabase: Supabase is the general Postgres+auth+storage Firebase alt; InsForge’s catch is agent-native MCP/CLI control of the same class of backend, not a better dashboard alone. Self-host still means you run Postgres and the compose stack.

  4. 4.Google Workspace CLIApache-2.0 first-party gws CLI — Drive, Gmail, Calendar, agent skills

    Free / OSS · Apache-2.0 · 31.7k GitHub stars

    VerdictApache-2.0 Workspace CLI. First-party org tooling for agents; not a Google support SLA.

    CatchFirst-party googleworkspace org surface — but the README states it is not an officially supported Google product. Vs raw Workspace REST / Apps Script: this is the CLI/agent skill layer, not a new API. Needs a GCP project + OAuth; unverified apps hit scope limits; Workspace/Admin API quotas still apply.

  5. 5.SuperpowersComposable agent skills that force brainstorm → plan → TDD → subagent review

    Free / OSS · OSS/MIT · 302k GitHub stars

    VerdictMIT agent methodology. Install when your agent skips specs and tests; not a replacement for the harness itself.

    CatchYou still need a strong coding harness and model budget; Superpowers is process, not an agent runtime. Optional visual-companion telemetry (opt out via SUPERPOWERS_DISABLE_TELEMETRY / Claude DisableTelemetry). Vs agent-skills (Addy Osmani lifecycle pack) and ECC (multi-host skill ecosystem): Superpowers is the opinionated SDLC methodology that hijacks the session start, not a general skill library or host-agnostic plugin bag.

  6. 6.Agent Skills (Addy Osmani)Production lifecycle skills — /spec /plan /build /test /review /ship

    Free / OSS · OSS/MIT · 108k GitHub stars

    VerdictMIT production skill pack. Reach for it when you want explicit /spec→/ship gates across many harnesses.

    CatchPer-skill installs can miss shared `references/` checklists — prefer whole-repo or full pack install. Still markdown discipline, not a runtime that forces compliance if the host ignores skills. Vs Superpowers (session-hijacking SDLC methodology) and knowledge-work-plugins (Anthropic official packs): this is the Google-flavored lifecycle library you pick skill-by-skill, not an automatic brainstorm→subagent loop.

  7. 7.Stitch SkillsGoogle Labs agent skills and plugins for the Stitch design MCP

    Free / OSS · Apache-2.0 · 8.5k GitHub stars

    VerdictApache-2.0 Stitch-oriented agent skills. Use when coding agents should drive Google Stitch design/build flows.

    CatchVs generic agent-skills packs: this library is Stitch-specific — useful when you are on Google Stitch, not a universal design system. Stitch product access and quotas remain Google-side constraints; the skills repo does not replace that.

  8. 8.ImpeccableApache design language/skills that make AI harnesses better at UI

    Free / OSS · Apache-2.0 · 82.8k GitHub stars

    VerdictApache design skill when your coding agent ships samey SaaS UI and you want PRODUCT.md + detectors in-loop; not a substitute for an agent runtime.

    CatchVs Superpowers and agent-skills packs: Impeccable is a design-language/skills layer for UI quality, not a coding agent and not a general agent-skills monorepo. Node ≥22.18 for the npx installer path; star count is extreme (~70k) — treat momentum as discovery noise until the skill actually changes your harness output.
