An integrated, three-part platform built around BigBlueButton, the open-source video-conferencing engine behind many LMS platforms. BluePanel Academy is the classroom layer institutions use directly — HD video, whiteboard, screen sharing, live polling and chat, automatic recording, multi-institution tenancy with role-based access (system admin / institution admin / instructor / student), passwordless direct-login links for students, bulk/Excel user import, attendance and performance analytics, and Persian-calendar-aware scheduling. It currently runs 500+ classes for 2,000+ active students in production with a 99.9% uptime target.

Convertor is the companion pipeline that batch-converts raw BigBlueButton recordings into shareable MP4 — up to 200 recordings in a single batch — using FFmpeg, and can pull straight from a live BBB player without a manual export step. Monitor closes the loop with a real-time ops dashboard across every connected BBB server: CPU/memory/load, live session and webcam counts, a searchable recording library with publish/unpublish/rename/delete controls, historical charts and instant alerts — wired up purely through BigBlueButton's official API, so onboarding a new server is just an address and a shared secret.

• Multi-tenant classroom platform: role-based access, bulk import, passwordless student links
• FFmpeg-based batch pipeline: up to 200 recordings converted to MP4 per run
• Real-time multi-server monitoring dashboard with historical charts and alerting
• Bilingual (Persian/English) UI with Persian-calendar-aware scheduling
• In production today: 500+ classes, 2,000+ active students, 99.9% uptime target

A tutorial platform, written entirely in Farsi, that teaches SQL and relational database design from first principles through to professional topics — SELECT, WHERE and JOINs, then transactions, indexing, execution plans and SQL injection. The curriculum runs 12 chapters and 60+ lessons, ordered the way SQL Server is actually used in production: querying and aggregation first, then database design, T-SQL programming (views, stored procedures, functions), transactions and isolation levels, indexing and query optimization, and security.

Every lesson pairs with a real, in-browser SQL playground — no install, no server, no signup. Learners write and run actual queries against sample schemas and see results instantly, then apply what they've learned to four realistic capstone projects: a school, an online store, a library and a staff-management system. Progress saves automatically in the browser, and the whole project is free and open-source.

SELECT s.full_name, ROUND(AVG(e.score), 2) AS avg_score
FROM students s
JOIN enrollments e ON e.student_id = s.id
GROUP BY s.id
ORDER BY avg_score DESC;

• In-browser SQL playground — write and run real queries with no install, server or signup
• 12 chapters, 60+ lessons: querying, JOINs, transactions, indexing, execution plans, security
• Four capstone projects on realistic schemas: school, online store, library, HR
• Native Persian-language curriculum with automatic progress tracking, 100% free and open-source

A free, no-signup IP intelligence tool. Visitors get their public IP address plotted on an interactive map alongside country, region, city, ISP, ASN, carrier, timezone and currency data. A built-in security panel flags whether the address is exiting through Tor, a known proxy or VPN, a datacenter, or a security blocklist — useful for fraud checks and access-control decisions.

Because a lot of real usage happens outside a browser, the same data is available straight from the shell: plain curl requests return plain text, the bare IP, or a full JSON payload — handy inside shell scripts, SSH sessions, container entrypoints or headless servers where opening a browser isn't an option. A companion subnet calculator takes an IPv4 address plus a mask or CIDR and instantly returns the network address, broadcast address, usable host range and host count.

curl show-ip.ir
curl show-ip.ir/ip
curl show-ip.ir/json

• Content-negotiated CLI output via curl — plain text, IP-only, or JSON
• Interactive map-based geolocation: country, region, city, ISP, ASN, carrier
• Security check for Tor, proxy, VPN, datacenter and blocklist exit nodes
• IPv4 subnet & CIDR calculator built in

A self-serve repository that bundles Linux software and every one of its dependencies into a single downloadable archive, so it can be installed on servers with no internet access at all — common in air-gapped, high-security or bandwidth-restricted environments.

Pick a distribution — Ubuntu 22.04/24.04, Debian 11/12, Rocky Linux 8, CentOS 7/Stream 8/9, Fedora or openSUSE Leap — and a tool: PHP, Python, Node.js, Java, Go, Docker, or a database engine like MariaDB, MySQL or PostgreSQL. Download the archive, copy it across on a USB stick or an internal transfer, and run a single install script. No dependency resolution at install time, no partial installs, no internet required.

• One archive per distro/tool combination, with dependencies pre-resolved
• Single install.sh — no manual dependency chasing on the target host
• Covers 6+ major distro families and the runtimes/databases teams actually run
• Built for air-gapped, sanctioned-bandwidth or high-security networks

A tutorial platform, written entirely in Farsi, that teaches 32 popular JavaScript and CSS libraries and frameworks — from Vue.js and Alpine.js to Bootstrap and Tailwind CSS, jQuery, Lodash, Axios and Day.js, Chart.js, D3.js and Three.js, GSAP, Anime.js and Swiper — through hands-on interactive examples instead of static documentation.

Every library page ships with a live, editable code playground: change the code and see the rendered output instantly, with no build step and nothing to install. The whole platform also runs fully offline, so it doubles as a self-contained reference a developer can keep on a laptop with no internet connection at all.

• Live, editable code playground per library — instant visual feedback, no build step
• Covers 32 libraries: frameworks (Vue.js, Alpine.js), CSS (Bootstrap, Tailwind), utilities (jQuery, Lodash, Axios, Day.js), visualization (Chart.js, D3.js, Three.js) and animation (GSAP, Anime.js, Swiper)
• Fully offline-capable — zero internet connection required to learn or reference
• Native Persian-language tutorials, built for Farsi-speaking developers

An open-source terminal UI, written in Go, that replaces raw ovftool command lines and repetitive vSphere web-client wizards with a fast, keyboard-driven cockpit. It shows a live tree of datacenters, clusters, hosts, VMs, templates and datastores with real-time usage gauges, and a guided 7-step deploy wizard reads the target OVF/OVA descriptor to prompt only for the properties it actually needs — from a local file or a URL.

Cloning and exporting VMs are single keystrokes (F5 / F6) with streamed progress bars, connection profiles are saved with AES-GCM encrypted credentials at rest, and it works against both standalone ESXi hosts and full vCenter inventories, with auto-refresh and four built-in themes.
