Port Radar for macOS
Juan Sebastian Solano
Free open-source Mac menu bar app that lists every listening localhost port and uses on-device Apple Intelligence to explain what each process is.
Key features
- Menu Bar Port Scanner: Lists every listening localhost port in the menu bar with port number, PID, owning project, runtime, and the exact command line.
- Apple Intelligence Explanations: Ask in plain language what a process is, why it has been running, and whether stopping it is safe; answers are generated on-device with no cloud call.
- Project Grouping: Groups processes by the project directory that owns them and flags shared or orphaned processes with no obvious parent.
- One-Click Cloudflare Tunnels: Share any local port as a public URL through a Cloudflare quick tunnel, auto-installing cloudflared with no CLI, ngrok, or account setup.
- Clean Process Control: Stop a process gracefully or force-quit it with a confirmation step, directly from the menu bar.
- Live Tunnel Management: See which tunnels are currently live and public, copy their URLs, and stop them at any time.
- Fully On-Device Privacy: All inspection and AI explanation happens locally; no process data or command lines are sent off the machine.
- Open Source Under Apache 2.0: The full source is published on GitHub, so the app can be audited or built from source.
Best for
- Port Conflict Debugging: Finding out which forgotten process is holding port 3000 before starting a new dev server.
- Runaway Process Triage: Identifying a Node or Python process quietly eating CPU and deciding whether it is safe to kill.
- Preview Sharing: Handing a teammate or client a live public URL for a work-in-progress local app in seconds.
- Multi-Project Development: Keeping track of which of several simultaneously running projects owns each active port.
- Onboarding and Handover: Letting a developer new to a codebase understand what the local stack actually starts up.
- Privacy-Sensitive Environments: Getting AI assistance about local processes in settings where sending command lines to a cloud model is unacceptable.
SubtitleGenerator
SubtitleGenerator
A browser-based AI subtitle generator that flags low-confidence words for fast correction and offers 33 caption styles, with no signup to start.
Key features
- Confidence-Flagged Corrections: Automatically flags every low-confidence word with its confidence percentage so you review only the cues that are actually uncertain instead of proofreading the whole transcript.
- Per-Cue Re-Transcription: Re-runs transcription on a single cue rather than the entire video, letting you fix one misheard name or term without reprocessing the file.
- 33 Caption Styles in Six Families: Ships clean, creator, karaoke, cinematic, pop and branded style families where typography, framing, highlighting and motion are designed together, from Clean Lower Third to Karaoke Fill to Comic Burst.
- On-Device Video Handling: Keeps the uploaded video on your own device through the browser workflow rather than requiring an upload to a media server.
- No-Signup Free Tier: Lets you upload, transcribe, style and export without creating an account, with all 33 styles unlocked from the start.
- Full-Track Translation: Paid plans add translation of the entire subtitle track inside the same editor, so styling and timing carry over rather than being rebuilt per language.
- Multi-Format Export: Exports to eight subtitle formats plus HD video without a watermark on paid plans, covering Premiere Pro, TikTok and YouTube caption workflows.
- Saved Brand Styles: Paid plans allow custom fonts and saved brand styles so a team's caption look stays consistent across every video.
Best for
- Short-Form Social Captions: Add TikTok, Reels or YouTube Shorts captions in a creator or pop style without opening a video editor.
- Podcast and Interview Clips: Caption conversation-paced audio and quickly correct proper nouns and names that transcription models routinely mishear.
- Course and Tutorial Videos: Produce accurate captions for dense explanatory content and screen recordings where technical terms need checking.
- Premiere Pro Handoff: Generate and correct a subtitle file in the browser, then export it in the format an existing NLE timeline expects.
- Multilingual Distribution: Translate a finished subtitle track into additional languages in the same editor to publish one video across markets.
- Accessibility Compliance: Produce reviewed, human-corrected captions for published video so content meets closed-captioning expectations.
