TooManyTabs
Ever tried having 20 tabs or more open in Chrome? You can’t even see the favicon of the tabs, not to mention the tab titles. If that happens to you, TooManyTabs is a must-have extension that manages your tabs, reduces your tab overflow, and saves your sanity. Suspend idle tabs and save memory, organize with custom columns. Remember recently closed tabs (within TMT). With TMT you're going to have a clear preview of each tab's content (fills up gradually as you use), be able to sort tabs by creation time, domain or title, and suspend idle tabs and save memory, organize with custom columns.

Osaurus
Osaurus is a native AI harness for macOS that lets users run open models entirely on their Mac, connect cloud models when greater capability is needed, and carry shared memory across them. Built in Swift for Apple Silicon, it works fully offline with local models through Ollama, MLX, or LM Studio, keeping conversations, code, files, settings, agents, skills, and provider keys on the device unless the user explicitly chooses a cloud provider. A system-wide chat overlay provides quick access from any app, while separate agents can be created for coding, research, file organization, and other jobs, each with its own prompt, history, and memory. Osaurus distills past conversations into relevant facts, loads packaged skills when tasks require them, and gives agents scoped access to working folders, file search, Git, and other tools. Agents can run code in an isolated sandbox, delegate work to subagents, operate on schedules, respond to folder changes, use voice input, and generate images.

Smart Jelly
Smart Jelly is a macOS personal AI assistant that brings together work context from apps and websites a user allows, meetings, messages, email and notes. It builds encrypted memory on the Mac that users can query by text or voice, with answers linked to sources. Features include cross-app dictation, voice assistance, meeting preparation, in-call prompts, meeting notes and follow-up task tracking. Through a connected Google account, it can draft emails and create documents, spreadsheets, slides and calendar events for review. Optional browser agents carry out web tasks with visible steps and confirmation before payments. Users can expose selected memory read-only to other assistants through MCP. Designed for individual knowledge workers, Smart Jelly runs on Apple silicon Macs with macOS 14 or later. Usage allowances vary by plan; agents are in early access.

Agent Substrate
Agent Substrate is an open-source runtime for operating isolated, stateful agent and code-execution sandboxes on Kubernetes. It coordinates actor and worker lifecycles, places active workloads on a shared pool of ready capacity, and can suspend idle environments while preserving memory and filesystem state for later resumption. Sandboxes use gVisor or Cloud Hypervisor microVM isolation, with per-actor identity and network controls. Agent Substrate is designed for platform and infrastructure teams building agent-hosting services, coding environments, and other workloads that execute untrusted or intermittent tasks. The core project is Kubernetes-portable; Google Cloud also provides GKE-optimized deployment tooling. Optional Filestore agent volumes can persist workspaces across suspend and resume cycles.
