saschagrunert/demo — A framework for performing live pre-recorded command line demos in the wild 📼

Description and use

**Brief summary**
saschagrunert/demo is a Go‑based framework that lets engineers run live, pre‑recorded command‑line demos that behave like real terminals, making it easy to showcase scripts, CI pipelines, or database workflows. With 329 stars, recent commits and a clear CLI/SDK surface, it is positioned as a practical tool for speeding up development, review, and CI feedback loops.

**Value**

• **Time savings** – Developers can record a demo once and replay it on demand, eliminating repetitive manual steps in onboarding, documentation, or CI verification.
• **Consistency** – Because the demo runs in a controlled, reproducible environment, the output is predictable, reducing “works on my machine” issues.
• **Improved feedback** – CI jobs can embed demo runs to illustrate what a pipeline does, giving reviewers visual context without extra narration.

**Practical adoption path**

1. **Evaluate the CLI/SDK** – Clone the repo, run the provided examples, and verify that the demo output matches your own scripts.
2. **Integrate into local workflows** – Replace ad‑hoc shell scripts with demo run <script> calls; store the generated demo files in your repo for versioning.
3. **Add to CI pipelines** – Use the CLI as a step in GitHub Actions, GitLab CI, etc., to generate a video or terminal transcript that is attached to build artifacts or pull‑request comments.
4. **Roll out to teams** – Document the standard pattern (record → commit → run) and provide a small wrapper script or Makefile target to make adoption frictionless.

**Production readiness**
The project scores high on readiness: it has recent activity (last commit 2026‑05‑13), a healthy star/fork count, and clear implementation signals (CLI, Go SDK, well‑defined topics). While the license and security posture still need a final check, the active maintainer base and ecosystem signals suggest it is safe for a pilot in production environments, especially for internal tooling or CI augmentation.

Problem

saschagrunert/demo helps engineers save time in daily development and review loops.

Outcome

High for an OSS candidate: recent activity, adoption, and ecosystem signals are strong enough for a serious pilot.

Workflow

• speed up developer workflows
• automate local engineering tasks
• improve CI feedback
