Can Headliner be vibe coded?
Create captioned audiograms and short social clips from user-owned audio
The core loop is buildable, but a dependable replacement becomes a substantially larger project. For Headliner, create captioned audiograms and short social clips from user-owned audio. The hard boundary is rendering infrastructure, templates, media hosting, and platform-specific presets, plus audio infrastructure, distribution, and production polish.

The achievable core
- Import user-owned spoken-word audio, perform practical cleanup, assemble captioned audiograms and short social clips, and export production files plus show notes.
- Publish episodes with an RSS feed, chapters, and reliable audio hosting.
- A responsive interface with real empty, loading, success, and error states.
The parts a prompt cannot buy
- rendering infrastructure, templates, media hosting, and platform-specific presets
- remote studio reliability
- licensed music libraries
- hosting distribution
- Reliability at the vendor's scale is an operations problem, not a prompt.
- The last 20 percent is sync, migration fidelity, speed, and edge cases.

$19.99/mo
People still pay for Headliner because creators pay to remove fragile audio plumbing and publishing chores from a release schedule. The recurring cost buys codec support, loudness standards, transcription, storage, feeds, analytics, and deliverability to directories, not just the visible interface.

Build brief — a focused alternative to Headliner
Context
Headliner — Create captioned audiograms and short social clips from user-owned audio. It currently costs $19.99/mo.
The core loop is buildable, but a dependable replacement becomes a substantially larger project. For Headliner, create captioned audiograms and short social clips from user-owned audio. The hard boundary is rendering infrastructure, templates, media hosting, and platform-specific presets, plus audio infrastructure, distribution, and production polish.
This brief describes a focused, single-operator replacement for the part of Headliner that is genuinely reproducible. It is deliberately narrower than the product it replaces, and it says so in writing. Build the useful core; do not pretend to have rebuilt the rest.
What you are building
Import user-owned spoken-word audio, perform practical cleanup, assemble captioned audiograms and short social clips, and export production files plus show notes.
Publish episodes with an RSS feed, chapters, and reliable audio hosting.
A responsive interface with real empty, loading, success, and error states.
Requirements
Functional
Ffmpeg.
Local audio files.
Sufficient disk space.
Data and integrations
Optional transcription API key.
Each of these needs a real account, credential, or quota. Set them up before writing feature code.
Non-functional
Accessibility: semantic markup, labelled controls, visible focus, and reduced-motion support.
Security: server-side secrets, validated input, and no credentials in the client bundle.
Reliability: retries with backoff on external calls, and a clear failure state when a provider is down.
Portability: the operator can export their data and leave without losing it.
Implementation brief
Build a personal replacement for Headliner in an empty repository.
Use Python 3.12, FastAPI, ffmpeg, SQLite, and an HTMX interface; do not offer alternative stacks.
The core loop is: import user-owned spoken-word audio, perform practical cleanup, assemble captioned audiograms and short social clips, and export production files plus show notes.
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.
Create an upload queue and preserve originals in a read-only media folder.
Generate waveforms and non-destructive edit markers instead of rewriting source files.
Implement silence trimming, loudness normalization to -16 LUFS, fades, and noise-gate presets.
Add chapter markers, intro and outro slots, and a simple two-track timeline.
Produce a transcript and draft title, description, chapters, and social excerpts.
Export MP3, WAV, transcript, chapters JSON, and a complete project manifest.
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.
Deliberately leave out real-time remote recording.
Deliberately leave out podcast hosting and directory analytics.
Deliberately leave out licensed stock music and voice cloning.
Finish by running the tests and listing the exact commands used.
Delivery standard
Inspect the repository first, then write a short implementation plan before writing code.
Deliver the smallest complete end-to-end workflow first; every primary control must work against persisted data.
Use real validation and storage; never substitute fake dashboards, decorative controls, hard-coded success states, or mock integrations.
Include responsive layouts plus genuine empty, loading, success, validation, and failure states.
Keep secrets server-side in environment variables, provide .env.example, and never commit credentials or user data.
Add structured logs around every external call and return actionable errors without leaking sensitive details.
Write unit tests for the core logic and one automated test of the main user journey.
Finish with a README covering setup, architecture, data location, backups, tests, deployment, and known limitations.
Acceptance criteria
A clean install starts the app using only the README and .env.example.
The primary journey works from first visit through saved result, reload, edit, export, and deletion where applicable.
Invalid input, missing configuration, provider failure, and an empty database each have a usable state.
The interface works at 390px and 1440px, is keyboard navigable, and shows visible focus on every control.
Tests, type checking, linting, and a production build all pass with no ignored failures.
No part of the interface implies a live integration, security guarantee, or scale capability that was not actually built and verified.
Non-goals
Do not build these, and do not claim to have replaced them:
Rendering infrastructure, templates, media hosting, and platform-specific presets.
Remote studio reliability.
Licensed music libraries.
Hosting distribution.
Advanced mastering and support.
What you still own after launch
Secure credentials, rotate secrets, and handle provider rate limits.
Run migrations, backups, restores, and dependency updates.
Test the critical journey after every model, API, or hosting change.
Monitor failures and fix the edge cases a first prompt will miss.
Risk
Operational risk. The code is achievable; dependable data, integrations, and ongoing operations are the real cost.
Editorial confidence in this assessment: medium. No reviewed project implementation is linked yet.
