PortAura is a native macOS utility that shows which processes are listening on which ports, where they’re exposed, and what has changed since your trusted baseline. It helps you understand local services without digging through Terminal commands. Everything runs locally on your Mac.

A mission-control dashboard for teams shipping on Vercel. Connect your account and every project fills in live: traffic, deploys, uptime, and PageSpeed scores. Search Console and Bing show clicks, rankings, and indexing. SSL and domain renewals get a countdown, and failing GitHub checks get flagged. When a build fails, the menu-bar F turns red and a notification fires, even with the window closed, so you know a site's down before your clients do. Tokens stay on your Mac. One-time purchase.

jurniti is a private always-on box for your AI agent. Each agent gets its own Firecracker microVM with a KVM hardware boundary, the same primitive AWS uses for Lambda, not a shared Docker container. Bring your own model keys. They stay inside the guest. Pay, and the box is live in about three minutes: in-browser terminal, persistent disk, your subdomain. Claude Code, Codex, Hermes, OpenClaw, and other upstream agents. From $25/mo. 30-day money-back on the first purchase. No free trial.

Mailyte is the only platform combining team inboxes, transactional/API email, and marketing campaigns in one place — on your own domain. Most teams stitch together Workspace, Postmark, and Mailchimp; Mailyte replaces all three. It's also open source (AGPL-3.0): self-host free on your own hardware, or let us manage it — same product, no lock-in either way. Built-in SPF/DKIM/DMARC checks and a live delivery view keep your mail out of spam, out of the box.

The Minimalist Entrepreneur as 10 open-source Claude Code skills by Sahil Lavingia. Install the plugin, then run slash commands like /validate-idea, /mvp, /pricing, and /minimalist-review to apply the book to your own business. Free and MIT-licensed on GitHub.

Run Cloud Agents, control VS Code and JetBrains sessions, review Pull Requests, and respond to coding agents from your iPhone, iPad, or Android.

Developers wait on AI all day. That wait is an ad slot. One network, three doors. If you code: install the VS Code, Cursor or Chrome extension. A native ad while the model thinks. You keep 70%. We don't read your prompts. If you sell a developer tool: you show up in the IDE and the browser, targeted by the stack they actually use (React, Python, AWS). Pay €200, get €400 this week. If you shipped a chat app: npm i @idlen/chat-sdk. Three lines. Ads optional. No key, no ads. You keep 70%.

Give AI agents secure access to your infrastructure and workflow. With Buddy MCP agents can run pipelines, inspect logs, deploy apps, create sandboxes, publish artifacts and manage domains. Control exactly what they can access with workspace permissions and tool scopes. Works with Claude Code, Cursor, Codex, Copilot and other MCP clients.

OpenAI's managed version of the Codex harness to build cloud agents with one API call instead of your own orchestration. Handles long sessions, smart tool use, and subagents working in parallel. Runs on OpenAI or partner sandboxes. No extra fees beyond token and tool usage. Open source harness, public beta now.

One system for auth, payments, customer data, and analytics. One command to install. Launch a paid product the same day you start building.

Drop in your screens, frame them in the latest iPhone, iPad or Mac, add headlines, backgrounds and stickers, and export at the exact sizes App Store Connect asks for. Design the whole set side by side, tilt and scale devices, or start from a community template. Unlimited exports, no watermark, and no account needed to start.

Give your README a signature, your Discord a mascot, or your next blog post a character-art cover. Turn photos and logos into ASCII locally in your browser—free, with no signup or image upload. Start with a built-in example, compare before/after, and tune presets, detail and color. Copy text or Markdown; export TXT, PNG, SVG, HTML or ANSI. Text formats keep editable characters; image exports preserve the look. Try the neon jellyfish or make an 80-column fox README mark.

Developers use your APIs. Now agents do too. Elva discovers APIs from code, lets you choose what each audience can use, and runs your MCP servers with auth and analytics. Track agent activity and review changes as your code evolves

Web Search Agents are expert web crawling and research agents for your specific domain (company enrichment, regulations research, etc.). They self-learn your use case to go deeper into the sources that matter most to you, giving your AI deeper and more relevant web context. To get started, give your AI this link: https://docs.nimbleway.com/agent-onboarding.md

Stop writing a parser for every service. Pascal’s Pager uses AI to turn raw webhook JSON into clear iPhone Alerts.
