AI tools developers can use now

A practical directory of coding agents, agentic IDEs, app builders, frameworks, evaluation systems, and inference tools. Links point to official project or company pages; Pagish summaries are original and kept concise to avoid republishing vendor copy.

Coding agents and agentic IDEs

Tools that inspect repos, edit files, run commands, create diffs, and help developers move from prompt to reviewed code.

commercialOpenAI product
OpenAI Codex

multi-agent software work across local apps, CLI, IDE, cloud tasks, reviews, and long-running implementation

Strong fit when teams want supervised coding agents with logs, tests, diffs, and ChatGPT account integration.
commercialAnthropic product
Claude Code

terminal-native Claude coding workflows, repo edits, debugging, tests, and model-context-driven development

Good option for developers who already use Claude and want a command-line coding agent with local project context.
commercialproprietary editor
Cursor

AI-first code editing, codebase chat, autocomplete, agent edits, and VS Code-like workflows

Useful when developers want an AI-native editor rather than a separate terminal agent.
commercialGitHub product
GitHub Copilot

IDE completions, chat, CLI help, code review, GitHub-native agent workflows, and PR-oriented software work

Strong default for teams already centered on GitHub, especially with Copilot agent and review workflows.
commercialproprietary editor
Windsurf

agentic IDE workflows, Cascade, multi-agent command center, and model-flexible code editing

Worth tracking for teams comparing agentic IDEs and cloud/local agent coordination.
commercialCognition product
Devin

autonomous cloud software engineering, backlog tasks, migrations, PRs, tests, and multi-repo projects

Best evaluated on scoped engineering tasks where the team can review plans, logs, and pull requests.
commercial/open-core editorZed product
Zed AI

fast editor-native agent workflows, external agents, MCP, and real-time review of AI edits

Relevant for developers who care about editor speed and want to bring agents such as Codex, Claude, or OpenCode into Zed.
commercialSourcegraph product
Sourcegraph Amp

agentic coding in VS Code-compatible editors and the terminal, with team collaboration around threads

Useful for teams pairing AI coding with Sourcegraph code intelligence and MCP integrations.
5 tools

Open-source coding agents to watch

Open-source or source-available agents developers can run, inspect, extend, or pair with multiple model providers.

4 tools

App builders and browser development

Prompt-to-app tools for prototypes, web apps, hosted IDEs, and product teams that need working software quickly.

5 tools

Agent frameworks and app SDKs

Libraries and SDKs for building AI agents, RAG apps, tool use, workflows, and production AI applications.

4 tools

Evaluation, observability, and prompt operations

Tools for evaluating, tracing, monitoring, debugging, and improving AI applications after the first demo works.

5 tools

Local models, inference, and deployment

Developer tools for running models locally, serving models, routing providers, and deploying inference workloads.

Build stack

The AI builder stack is consolidating around model routing and evals

Frameworks, hosted inference, observability, vector retrieval, and eval harnesses are becoming the practical layer between model releases and production apps.

SDK adoption, repository velocity, model-provider support, and repeatable evaluation workflows.
Open source

Open repositories can reveal momentum before polished launches

Stars alone are noisy. Pagish weighs release cadence, issues, forks, maintainers, examples, and whether practitioners are actually building with a project.

New releases, docs quality, community examples, and production integrations.
Inference

Developer experience increasingly depends on inference economics

Tool choices are being shaped by latency, batch APIs, caching, quantization, GPU availability, and the ability to swap models without rewriting apps.

Pricing, rate limits, model catalogs, structured outputs, and deployment portability.
