Rube is an AI-powered universal connector that plugs 500+ apps directly into your favorite chat (VS Code, Cursor, Claude, Slack, etc.) without writing code or managing tokens. Built on Composio’s secure MCP gateway, it turns natural-language requests into instant cross-app actions—summarizing merged PRs in Notion, aliasing emojis in Slack, syncing Gmail to Jira, or orchestrating any workflow you can describe. Bring your own API keys or use shared credentials; once an app is connected, every teammate can invoke it from any client with the same URL. Personal makers start free, teams scale with granular roles and audit logs, while enterprise customers self-host for SOC 2-grade compliance. Zero setup, zero context switching, zero limits on tool calls—just chat and watch Rube glue your stack together.

JsonGrid
JsonGrid is an all-in-one online toolkit that turns raw JSON into an editable, filterable spreadsheet-style grid, making data exploration, editing, validation and sharing dramatically faster for developers, analysts and product teams. Built as a zero-install web app plus a Chrome DevTools extension, it delivers instant visualization of any JSON payload—from API responses to config files—through an intuitive table that supports inline edits, advanced search, collapse/expand nested nodes, one-click format/minify, real-time validation, and direct file import/export. The core engine parses deeply nested structures without flattening, preserves data types, and syncs changes back to clean JSON in real time. A freemium plan offers unlimited grid viewing and basic edits, while paid tiers unlock enterprise collaboration, schema enforcement, history, and on-prem embedding through a headless React component. No registration is required to start, and every operation happens client-side, ensuring privacy and sub-second performance even on multi-megabyte payloads. Whether you are debugging a REST endpoint, cleaning analytics dumps, or teaching JSON concepts, JsonGrid collapses hours of tedious text editing into a few clicks, becoming the missing GUI for the world’s most common data format.

FreeZero Sheets
Zero Sheets is a no-code bridge that turns any Google Spreadsheet into a secure, fully-featured REST API in under a minute. Positioned as the fastest way to go from spreadsheet to backend, it lets developers, agencies and product teams skip database setup and server maintenance while still delivering production-grade JSON endpoints. Target users range from indie hackers validating MVPs to enterprise departments that need an instant internal CMS. Core features include dynamic sheet-to-endpoint mapping, token or header authentication, unlimited tabs per API, CRUD access and global CDN caching. Content-wise, the platform treats Sheets as living databases—column headers become keys, rows become objects, and cell edits are reflected in real time via webhook, giving non-technical stakeholders a familiar editing interface while preserving developer ergonomics. UX is deliberately minimal: paste a Sheet URL, tick the tabs you want to expose, copy the generated base URL and you’re live. Under the hood, an OpenAPI 3 spec is auto-generated, rate-limit tiers are enforced through edge workers, and every request is validated against inferred column types to prevent dirty writes. This makes Zero Sheets ideal for rapid prototyping, deploy-less backends, beta-user management, content-heavy landing pages and lightweight e-commerce catalogs.

FreemiumAppShots
AppShots is a lightning-fast, browser-based designer that turns raw app screens into polished, store-ready screenshots for iOS and Android.

Built for indie devs, marketers and agencies, it delivers consistent branding, higher conversion tests and store approval on the first submission.

Freemiumnanochat
nanochat is a bite-sized, end-to-end LLM stack that lets anyone train and chat with their own ChatGPT clone for roughly the cost of a nice dinner. Built by Andrej Karpathy as the capstone for the upcoming LLM101n course, the repo packs tokenization, pre-training, fine-tuning, RL, evaluation, and a web UI into a single, 8 k-line Python/PyTorch codebase that runs start-to-finish on one 8×H100 cloud node in under four hours. The default “speedrun” produces a 1.9 B-parameter transformer (d32) that’s competitive with GPT-2 while remaining fully hackable—no sprawling config factories, no black-box binaries, just concise scripts you can read, modify, and fork in minutes. A simple bash speedrun.sh downloads data, trains the model, saves checkpoints, prints a report card (CORE, MMLU, GSM8K, HumanEval, etc.), and launches a Gradio chat interface on port 8000. Larger tiers (~$300, ~$1 k) are one-line tweaks away, and everything gracefully downscales to a single GPU or even CPU/MPS for tinkering. MIT licensed, dependency-lite, and intentionally minimal, nanochat is the fastest path from curiosity to “I trained my own LLM.”
