Concurrent Delivery

Delta is a multiplayer environment for coding with agents, developed by the creators of Zed. It keeps agent conversations, code changes, reviews, and teammates in shared threads so that reasoning remains associated with the resulting work. Teammates can be @-mentioned into threads, review changes line by line and send feedback to the agent, mirror terminals in real time, and check out a teammate's work locally. The service is offered as native macOS, Linux, and Windows applications with a mobile app, and the videos describe it as model- and harness-agnostic, with cloud deployment and cloud runners; it was in private beta at the time described.

ChatDev is an open-source multi-agent framework from OpenBMB. Its original ChatDev 1.0 design models a virtual software company in which role-based agents such as a CEO, CTO, and programmer collaborate through specialized functional seminars to carry out software development tasks including design, coding, testing, and documentation. The current ChatDev 2.0, called DevAll, is a zero-code multi-agent orchestration platform. Users configure agents, workflows, and tasks to build and run customized multi-agent systems for scenarios such as software development, data visualization, 3D generation, and deep research.

In Parallel is a platform that turns the conversations, documents and decisions around an initiative into persistent business context that teams and their AI tools and agents can use. It is positioned to provide living context for collaboration and for AI-driven workflows.

Deft is a self-hostable, open-source workspace where people and AI agents share chat, tasks, knowledge, calendar context, approvals, and action history. Its core workflow captures discussions as durable knowledge, lets the Defty agent use workspace context to propose task details, and routes proposed agent actions through configurable approval and trust policies before recording the approved work and its receipts. It also provides real-time conversations, task views, notes, knowledge graphs, calendar features, personal MCP connections, agent employees, native workspace tools, scoped access, revocation, and provider-neutral support for hosted or local AI providers. Deft can run without an AI provider as a conventional workspace. The self-hosting path uses Docker and PostgreSQL with pgvector; the repository is an alpha intended for technical evaluation, internal use, and controlled pilots. It is licensed under AGPL-3.0-only.

Kandev is an open-source, self-hostable AI Kanban and development environment for orchestrating coding agents and reviewing their work. It organizes tasks in Kanban and pipeline views, supports parallel execution and multi-step agentic workflows, and isolates concurrent work with Git worktrees. Its integrated workspace combines a file editor, file tree, terminal, browser preview, chat, and Git changes for reviewing and iterating on agent output. Agents can run through local, Docker, SSH, or cloud runtimes, with support for multiple agent providers; the project also provides configurable workflows, agent profiles, prompts, review gates, scheduled or webhook-triggered automations, and no telemetry.
