Paul Sawers writes that Zed has launched Delta, a collaborative development platform now in public beta that replaces pull requests with shared threads preserving the full conversation between developers and coding agents. The move responds to both volume pressure on GitHub — monthly commits jumped from roughly 1 billion in 2025 to 2.9 billion by August 2026 — and a structural mismatch: when much of the reasoning behind a change happens inside an agent conversation, a bare diff gives reviewers little context. Zed has already disabled pull requests on Delta's own repository, where 33 developers have landed 570 changes to main through threads, and co-founder Nathan Sobo expects the company to fully leave GitHub within a few months.
- DeltaDB, the version control layer beneath Delta, records individual edits and conversation events between Git commits, a finer granularity than Git's commit-based model; Zed calls these individual records "deltas."
- Sobo predicts the thread will replace the commit or branch as the fundamental unit of software development, with commits remaining only as checkpoints.
- Competitors share the thesis: SpaceX-owned Cursor launched Origin in August 2026, and GitLab has Project Switch in private beta.
- Delta works with existing Git repositories, so contributors who don't adopt it can still submit conventional pull requests; the platform is free during public beta with paid plans to follow.
- Zed raised $32 million from Sequoia Capital in August 2025, a round that also teased DeltaDB.

Oh-my-mermaid is a tool designed to bridge the gap between rapid large language model code generation and human comprehension by automatically generating architecture documentation. It scans codebases to produce various perspectives, such as data flow or system structures, which are rendered into Mermaid diagrams and Markdown files stored within a local `.omm` directory. By visualizing these structures through an interactive viewer, it transforms complex software architectures into navigable maps for developers.
- Integrates with tools like Cursor and Claude Code via specialized commands
- Offers cloud synchronization for private or public sharing on ohmymermaid.com
- Uses a recursive filesystem structure where complex nodes become expandable groups in diagrams
- Provides a command-line interface to manage configuration, updates, and viewing

Open Code Review is an AI-powered CLI tool designed for automated, high-precision code reviews. Originally developed as Alibaba Group's internal assistant, the project uses a hybrid architecture that combines deterministic engineering with LLM agents to provide stable and accurate feedback. Unlike general-purpose agents, it employs smart file bundling and fine-grained rule matching to maintain context and prevent issues like position drift or incomplete coverage on large changesets.
Key features:
- AI-driven line-level review comments
- Hybrid architecture combining hard constraints with dynamic decision-making
- Support for various LLM endpoints including OpenAI and Anthropic
- Seamless integration with CI/CD pipelines and coding agents like Claude Code
- Customizable rule sets for specific project requirements

graphify is an AI coding assistant skill that transforms codebases, documents, and images into a structured, queryable knowledge graph. By utilizing deterministic AST parsing via tree-sitter for code and multimodal LLM capabilities for unstructured data like PDFs and screenshots, it creates a comprehensive map of concepts and relationships. This allows developers to understand complex architectures faster and find the "why" behind design decisions. A key advantage is its massive reduction in token usage per query compared to reading raw files, making it highly efficient for large-scale projects. The tool supports 19 programming languages and integrates seamlessly with platforms like Claude Code and Codex, providing an interactive, persistent, and highly organized way to navigate any codebase or research corpus.
An open-source background coding agent. Designed to understand, reason about, and contribute to existing codebases. Licensed for open-source use under MIT License. It sets up isolated execution environments for AI agents to work on GitHub repositories with tools to understand code, edit files, and much more.
OpenHands is an open platform for AI software developers as generalist agents. It allows agents to modify code, run commands, browse the web, call APIs, and more, aiming to automate software development tasks.
GitHub Copilot Extensions allow developers to use natural language to query documentation, generate code, retrieve data, and execute actions on external services without leaving their IDEs. They support public extensions from companies like Docker, MongoDB, Sentry, and allow developers to create their own extensions for internal libraries or APIs.
