Scheduling and meetings decision
Butter
A consolation build is possible, but the paid product's decisive value sits outside a solo rebuild. For Butter, host a facilitated workshop interface around a modest private video room. The hard boundary is workshop tools, templates, media reliability, engagement features, and integrations, plus real-time media infrastructure and reliability.

Every project below is open source and already does this job today. Fork one, self-host it, or take the parts you need — the build prompt further down assumes an empty file, and this is the shortcut past that. Licences differ; check the one on each card before you ship.
What a replacement has to do
- Host facilitated workshops in a modest private video room, issue signed room links, and keep recordings only when every participant is clearly informed.
What it still won’t have
- workshop tools, templates, media reliability, engagement features, and integrations
- global low-latency media network
- dial-in and telephony
- large webinars
- transcription, support, and compliance
What remains hard
- Infrastructure at scale
- Execution quality

Paying is—cheaper in year one.
On cash alone, building overtakes the subscription at 1 seat.

Runnable build prompt
Build a closest honest personal substitute for Butter in an empty repository. Use Docker Compose, Jitsi Meet, a small Next.js 15 control panel, PostgreSQL, and TURN; do not offer alternative stacks. The core loop is: host facilitated workshops in a modest private video room, issue signed room links, and keep recordings only when every participant is clearly informed. Make the first run work locally with one documented command. Store all user data locally by default and make export straightforward. Put secrets in .env, ship .env.example, and never commit credentials. Deploy Jitsi Meet through pinned Docker images and configure a dedicated TURN service. Build an owner panel for rooms, signed invitations, expiry, lobby mode, and participant limits. Show connection diagnostics for camera, microphone, browser, bandwidth, and TURN reachability. Make recording disabled by default and require an on-screen consent state for every participant. Store room metadata and audit events, but do not store media unless explicitly enabled. Add health checks, bandwidth dashboards, backup, restore, upgrade, and incident instructions. Include clear empty, loading, success, and recoverable error states. Add input validation, safe filenames, and graceful handling of unavailable APIs. Write focused tests for the core transformation and one end-to-end happy path. Create a README with setup, architecture, permissions, data location, and backup steps. Do not add accounts, billing, telemetry, analytics, or a hosted control plane. Do not claim to reproduce proprietary data, network liquidity, regulated access, or frontier infrastructure. Deliberately leave out a global media edge network. Deliberately leave out public webinar scale and telephony. Deliberately leave out regulated recording, enterprise compliance, and guaranteed support. Finish by running the tests and listing the exact commands used.
