Inbox Zero Launches Open-Source Superhuman Alternative

Inbox Zero Mail is a free, open-source email client for Gmail and Outlook with keyboard-first workflows, unified inboxes, split inboxes, team comments, and cross-platform apps. Its optional AI tier sorts messages and drafts replies in the user’s voice. [Product Hunt](https://www.producthunt.com/products/inbox-zero-2)

// ANALYSIS

Inbox Zero’s strongest differentiator is ownership: it brings Superhuman-style speed and AI assistance to an open-source, self-hostable codebase.

–Web and desktop clients are open source, while the iOS app remains proprietary.
–The project already has meaningful traction, with 12.6K GitHub stars and 1.6K forks.
–Self-hosting gives privacy-conscious teams more control, but deployment still requires technical infrastructure.
–Its AI pricing undercuts premium email competitors, though the launch page lists $20/month while the current pricing page shows an $18 Starter plan.

AgentDecision-4B Makes Agent Loops 89% Cheaper

AgentDecision-4B is a LoRA-tuned Qwen3-4B adapter that handles bounded tool, argument, and completion choices inside agent harnesses, deferring uncertain states to larger language models. The paper reports 81.1–89.0% lower costs and up to 2.5× faster execution on familiar tasks, plus 91.5% success on shifted tasks. [Paper](https://arxiv.org/abs/2610.21412)

JevAgentHarness routes agent decisions with confidence gates

JevAgentHarness is an open-source proxy that routes routine agent decisions to fast models while escalating uncertain steps to stronger LLMs. Its AgentDecisionBench research reports major cost and latency reductions using per-choice confidence thresholds and the open AgentDecision-4B model.

git-ai brings server-centric Git to agents

git-ai is an MIT-licensed, open-source Git platform built for concurrent coding agents. It centralizes history, sparse data access, landing, and configurable conflict resolution on a server while retaining Git underneath. ([GitHub repository](https://github.com/feder-cr/git-ai))
