Show HN: Cosmic CLI – Build, deploy, and manage apps from your terminal with AI

Hacker News - Tue, 02/10/2026 - 2:01pm

Hi HN, I'm Tony, founder of Cosmic (a headless CMS). We just open-sourced a CLI that covers the full lifecycle of a content-driven app from creating the content model to deploying to production to updating the codebase all without leaving the terminal.

Here's what the full workflow looks like:

# Create a project with an AI-generated content model cosmic projects create # → "A recipe blog with recipes, categories, and authors" # Generate content cosmic content -p "Create 5 recipes with images across different categories" # Build a full-stack app wired to your content cosmic build -p "A modern recipe blog with search and category filtering" # → Generates a Next.js app, pushes to GitHub # Deploy cosmic deploy start --watch # → Deployed to Vercel # Later: update the existing codebase with natural language cosmic update recipe-blog -p "Add dark mode and a favorites feature" -b feature-branch # Create a PR and merge cosmic repos pr create cosmic repos pr merge 1 # → Auto-deploys to production That's the part I think is interesting: it's not just one step, it's the full loop. Create content, build the app, ship it, iterate on it, merge and redeploy. Each step is a single command.

A few of the more technically interesting pieces:

AI agents. You can create three types: content agents (CMS operations), repository agents (code changes on branches), and computer use agents (browser automation via Puppeteer with AI vision). Chain them into multi-step workflows with scheduling.

Interactive shell. "cosmic shell" drops into a REPL where you navigate workspaces and projects like a filesystem: cd, ls, pwd. System commands with ! prefix. No cosmic prefix needed.

Multi-model. Supports Claude Opus/Sonnet/Haiku, GPT-5/5.2/5-mini/4o, and Gemini 3 Pro. Set a default or specify per-command.

It also handles the day-to-day stuff you'd normally do in a dashboard: billing, team roles, webhooks, domain/DNS config, environment variables.

Built with TypeScript and Commander.js. MIT licensed.

Show HN: Multimodal perception system for real-time conversation

Hacker News - Tue, 02/10/2026 - 1:58pm

I work on real-time voice/video AI at Tavus and for the past few years, I’ve mostly focused on how machines respond in a conversation.

One thing that’s always bothered me is that almost all conversational systems still reduce everything to transcripts, and throw away a ton of signals that need to be used downstream. Some existing emotion understanding models try to analyze and classify into small sets of arbitrary boxes, but they either aren’t fast / rich enough to do this with conviction in real-time.

So I built a multimodal perception system which gives us a way to encode visual and audio conversational signals and have them translated into natural language by aligning a small LLM on these signals, such that the agent can "see" and "hear" you, and that you can interface with it via an OpenAI compatible tool schema in a live conversation.

It outputs short natural language descriptions of what’s going on in the interaction - things like uncertainty building, sarcasm, disengagement, or even shift in attention of a single turn in a convo.

Some quick specs:

- Runs in real-time per conversation

- Processing at ~15fps video + overlapping audio alongside the conversation

- Handles nuanced emotions, whispers vs shouts

- Trained on synthetic + internal convo data

Show HN: Traction – Security readiness framework for scaling SaaS teams

Hacker News - Tue, 02/10/2026 - 1:57pm

I'm so tired of vendors showing up with a SOC 2 thinking that closes the deal. Great, you passed an audit — but you don't support SSO, I can't get logs out of your platform, and your engineers have access to all my data. I don't care about your SOC 2. Yes, you need it to prove to me you aren't some vibe-coded app running on the side (some of these actually do have SOC 2s too), but what I care about beyond that is that I can secure your tool according to my stack and my requirements. Use Traction to show me what product security you've implemented. Please.

Show HN: Tasty A.F. – Turn Any Online Recipe into a 3x5 Notecard

Hacker News - Tue, 02/10/2026 - 1:56pm

I built an app that turns any online recipe into a printable 3x5 index card.

If you cook from the internet, you know the pain: scrolling past a 2,000-word story about someone's grandmother just to find the ingredient list. Then trying to read it off your phone with wet hands.

So I built Tasty A.F. — paste a recipe URL, and it uses AI to extract the essentials and format them onto a clean, printable notecard.

How it works: - Paste any recipe URL - AI scrapes the recipe and generates a concise 3x5 card - Print it, stick it on the fridge or a notecard, and cook

Built with Python/Flask and the Anthropic Claude API, hosted on Railway.
