WhenFor.us VS CloudCLI

WhenFor.us's answer

• Vanilla JavaScript frontend, no framework
• Server-rendered pages with per-language subfolders

CloudCLI's answer:

CloudCLI is built with a modern JavaScript/TypeScript stack:

• Frontend: React with Vite for fast builds, Tailwind CSS for styling, and CodeMirror for the in-browser code editor with syntax highlighting
• Backend: Node.js powering the server and session management
• Infrastructure: Docker for containerized cloud sessions, with support for self-hosting
• Mobile: A dedicated mobile app for managing sessions on the go

The entire codebase is open source under AGPL-3 and available on GitHub.

WhenFor.us's answer

• vs. When2meet: same idea, but it works on a phone, looks like it was made this decade, and handles time zones.
• vs. Doodle: no account, no paywall, no ads, no "upgrade to see results."
• vs. Calendly / Cal.com: those are for booking one person's time. WhenFor.us is for finding when a group is free.
• vs. LettuceMeet / Rallly: comparable features, with a cleaner mobile experience and five languages.

CloudCLI's answer:

Compared to tools like GitHub Codespaces, CloudCLI is purpose-built for agentic development rather than traditional coding. Here's what sets it apart:

• AI-agent-first: While competitors give you a cloud IDE, CloudCLI gives your AI agents a persistent home in the cloud. Your agents keep working even when your laptop is closed.
• Open-source web UI and mobile app: No other CDE ships with both a browser-based UI and a native mobile app for managing sessions on the go. And it's all open source.
• Cross-device continuity: Start planning on your phone, continue in VS Code at your desk, or kick off from a Linear ticket. Your session context carries over seamlessly.
• Multi-agent support: Run Claude Code, Cursor CLI, OpenAI Codex, and Gemini CLI from one platform instead of managing separate setups.
• Affordable: Starting at €7/month for the managed service, or self-host for free with Docker.

WhenFor.us's answer

• Nobody needs an account. Not the organizer, not the participants. The link is the whole product.
• Built for the group chat, not the desktop. Most people open a scheduling link on their phone from WhatsApp, Discord or iMessage. The availability grid is designed for a thumb, not a mouse.
• The answer is visual. Everyone's free times overlay into a heatmap, so the best slot is obvious without reading a table.
• Nothing to clean up. No ads, no upsells, events delete themselves after they're over.

CloudCLI's answer:

CloudCLI is one of the only cloud development environments built specifically for AI coding agents. Where Codespaces and Gitpod give you a cloud editor, CloudCLI gives your agents a persistent home that stays alive 24/7. What makes it particularly valuable for teams: shared MCP servers and environment configs mean every developer starts from the same baseline. A full REST API means sessions can be triggered from automation tools, not just opened manually. Background agents can run overnight and produce PRs for review in the morning. And the entire platform is open source (AGPL-3) so teams can self-host on their own infrastructure.

WhenFor.us's answer

Anyone who has to get 4-15 people in the same place at the same time: D&D and board game groups, bands, sports teams, study groups, volunteer coordinators, families planning a dinner, and small remote teams scheduling a call across time zones. The common thread is that they organize in a group chat and nobody wants to install an app or create an account for it.

CloudCLI's answer:

CloudCLI is built for engineering teams that use AI coding agents as part of their daily workflow. This includes teams adopting agentic development practices with tools like Claude Code, Cursor CLI, or Codex who need shared environments where MCP servers, context files, and configurations stay consistent across every developer. It also serves engineering managers looking to integrate AI agents into existing workflows through API-driven automation with tools like Linear, Jira, and n8n. Solo developers and open-source contributors who want persistent remote access from any device are also a core audience, along with organizations that need to self-host for data sovereignty or regulatory compliance.

WhenFor.us's answer

Built out of frustration with the existing options: When2meet is unusable on a phone, Doodle keeps pushing paid plans, and everything else wants a login before you can do anything. The goal was a tool you can hand to a group chat and get an answer back from without anyone asking "what is this and why do I need an account." It launched in October 2026 and will stay free and ad-free.

CloudCLI's answer:

CloudCLI started as an open-source project to solve a problem every developer using AI coding agents hits: your agent ties up your terminal and stops working when your laptop sleeps. We built a cloud-native environment where agents run persistently, paired with an open-source web UI so anyone could manage sessions from a browser or phone. As teams started adopting it, the focus shifted to shared environments, where team-wide MCP servers, configurations, and context files could be maintained in one place instead of duplicated across every developer's machine. The project grew to 9,000+ GitHub stars organically with no marketing. Today CloudCLI offers both a free self-hosted option and a managed cloud service starting at €7/month.
