Catalog
1,301 developer tools across AI, design, development, and more. Start with the latest additions.
catalog / recommended
Editor-selected tools from the public catalog. Review scores and evidence status are disclosed separately, so a recommendation does not imply a Verified hands-on review unless the linked record says so.
Anthropic's agentic coding CLI
Anthropic's agentic CLI coding tool that delegates complex tasks to Claude directly from the terminal. Understands entire codebases via automatic context gathering, edits multiple files, runs shell commands, and manages Git workflows autonomously. Supports CLAUDE.md for persistent project instructions, integrates with VS Code and JetBrains, and uses Claude Opus/Sonnet with extended thinking for complex architectural decisions. Built for terminal-first developers.
OpenAI coding agent for app, editor, terminal, and cloud work
Codex is OpenAI's coding agent for software development across the Codex app, editor, terminal, and cloud tasks. It helps write, review, debug, refactor, and automate code, with ChatGPT plan access for managed surfaces and API-key usage for CLI, SDK, and IDE workflows. The open-source CLI and SDK support local repository work, while cloud features add GitHub review, Slack/Linear integrations, worktrees, skills, MCP, and automations.
Persistent AI teammates for cross-app work
Grok Bot is SpaceXAI's beta workspace for persistent AI teammates that use apps, websites, files, terminals, plugins, and MCP on a user-scoped cloud computer. Bots can learn routines, coordinate in parallel, and, when enabled by team policy, launch Cursor Cloud Agents that work on code in isolated environments and return pull requests and verification artifacts.
Autonomous AI software engineer by Cognition
Devin is Cognition's managed AI software engineer for delegating engineering tasks to cloud and desktop agents. It can plan work, navigate codebases, write and run code, test changes, open PRs, review/autofix issues, and collaborate through GitHub, GitLab, Bitbucket, Linear, Jira, Slack, and Teams. Current Devin surfaces include Devin Cloud, Devin Desktop, Devin CLI, Devin Review, Windows VM support, DeepWiki, Ask Devin, and team/enterprise controls.
The AI-first code editor
AI-first code editor built as a VS Code fork that deeply integrates LLMs into every part of the development workflow. Features Tab autocomplete with multi-line predictions, Cmd+K inline editing, AI chat with full codebase awareness, and Agent mode for autonomous multi-file edits with terminal execution. Supports GPT-4, Claude, and more with automatic context from project files and docs. Includes privacy mode for SOC 2 compliance. The leading AI-native IDE with 100K+ paying users.
Agentic coding tool by Sourcegraph (formerly Cody)
Amp is a multi-model coding agent for terminal, web, macOS/iOS, and IDE-connected workflows. Vendor docs describe the same agent and threads across surfaces, with remote Orbs, local Runners, Dial modes (low / medium / high / ultra), shared threads, MCP, plugins, and BYOK / linked ChatGPT subscriptions. Pricing spans a free Hobby tier, optional Megawatt ($20/mo) and Gigawatt ($200/mo) Individual plans, no-extra-charge Teams workspaces, pay-as-you-go credits, and Enterprise.
editorial / latest
Long-form reviews, head-to-head comparisons, and completed weekly diffs with visible sources and verification dates. Reviews disclose when hands-on evidence is complete, partial, missing, or still unclassified.
Aider vs Goose: Git-Native Pair Programmer or Extensible MCP Agent?
Aider and Goose are both free, Apache-2.0 terminal AI agents that run on your own model keys, and they differ mainly in workflow. This page compares them on documented features and existing Score reviews.
Amp vs Goose — Multi-Surface Agent or Open Local MCP Agent?
Amp and Goose both help developers run agentic coding workflows, but they emphasize different product shapes. Amp is Sourcegraph’s multi-surface coding agent spanning terminal, web, macOS/iOS, and IDE-connected threads, with freemium plans and BYOK options. Goose is Block’s AAIF-aligned open-source local agent — Desktop and CLI — built around MCP extensions, recipes, and model-agnostic BYOK or Ollama. Existing Scores: Amp overall 85 (Score date 2026-03-25); Goose overall 84 (Score date 2026-03-29). Overall is close; choose on multi-surface commercial agent vs open local MCP depth. Treat the scoreboard as review evidence with those dates, not the whole decision.
OpenCode vs Cline — Terminal Coding Agent or VS Code HITL Agent?
OpenCode and Cline both deliver open-source agentic coding help, but they live in different shells. OpenCode is an MIT coding agent spanning terminal, IDE extension, and desktop, with any-provider models and a polished coding-agent loop. Cline is an Apache-2.0 coding agent for editor, terminal, and SDK workflows that reads and edits files, runs commands, and asks for explicit approval unless you enable auto-approve. Existing Scores: OpenCode overall 83 (Score date 2026-09-05); Cline overall 84 (Score date 2026-03-25). Overall is close; choose on terminal coding-agent DX vs editor human-in-the-loop control. Treat the scoreboard as review evidence with those dates, not the whole decision.
Goose vs OpenCode: Local MCP Agent or Open-Source Coding Agent?
Goose and OpenCode both run open-source AI agents that help developers ship work from the terminal, but they emphasize different product shapes. Goose is an open-source, model-agnostic local agent from the Agentic AI Foundation (AAIF) lineage — Desktop, CLI, and API — built around MCP extensions, recipes, and BYOK or local Ollama. OpenCode is an open-source coding agent spanning a terminal interface, IDE extension, and desktop app, with any-provider models and a polished coding-agent loop. Use Goose when you want a privacy-forward local agent with deep MCP extensibility across code and broader workflows. Use OpenCode when you want a coding-agent surface across terminal, IDE, and desktop with strong day-to-day developer experience. Existing aicoolies Scores: Goose overall 84, speed 80, privacy 95, developer experience 78 (Score date 2026-03-29); OpenCode overall 83, speed 81, privacy 90, developer experience 86 (Score date 2026-09-05). Overall is close; choose on product shape first, and treat the scoreboard as secondary review evidence with those dates.

Using Devin Max across desktop and web, I delegated a cloud task and merged a PR. Screenshots, recordings, Fusion routing, and integrated review made the handoff easier to follow; ACP support offers a shared interface for other agents.
Read the Field Note →catalog / how it works
The shared rubric and evidence states behind scores, source checks, and verification dates.
scoring
aicoolies Score v1 defines overall quality, speed, privacy, and developer experience on a public 0–100 rubric. Reviews marked Verified also expose the test date, version, environment, artifact, and source-check dates; older scores are labeled separately.
freshness
Pricing and plan limits move constantly. A page shows a source-check or last-verified date only when that editorial check was recorded; routine CMS updates are not presented as verification.
honesty
Discontinued products leave the recommendations and move to the Graveyard with the date they shut down and what replaced them, instead of quietly rotting in a list.
open data
The catalog is published as CC-BY 4.0 JSON, an OpenAPI-described API, and an MCP server. Supported public catalog and guide URLs also answer in markdown on request, so agents can read the same published facts without scraping presentation markup.
community / most stacked
The tools developers actually put in their stacks.
build with us
Listings are free. The dataset is CC-BY 4.0. Agents can read the same published facts without scraping the page.
aicoolies Score v1 defines four 0–100 axes: overall, speed, privacy, and developer experience. Each review now discloses whether its test evidence is Verified, Partial, Not yet evidenced, or Legacy, and the full rubric is published on the methodology page.
Records display source-check and last-verified dates only when those checks have been completed. Missing verification metadata is left visibly unclassified rather than inferred from a routine edit. Confirmed discontinued tools can move to the Graveyard instead of lingering as live recommendations.
Yes. The tool, comparison, and review datasets are published as JSON under CC-BY 4.0, so you can use them with attribution to aicoolies.com. There is no API key and no signup.
Yes. Supported public catalog and guide URLs answer in markdown when requested, and the catalog is published as an OpenAPI-described JSON API and an MCP server. Public reads need no token at all.
No. Listings, scores, and recommendations cannot be bought and outbound tool links carry no affiliate parameters. aicoolies does sell clearly labeled sponsored placements (a sponsor rail and one sponsor per category); those never affect scores, verdicts, or rankings. The scoring rubric is published precisely so a ranking can be argued with instead of taken on trust.
A single editor, working from Izmir, Turkey, publishes the catalog under a named byline. The editorial team page lists who assigns the scores and how to reach them, and corrections sent with a source land in the next editorial pass.
Submit it with links to the official documentation and pricing. An editor checks the supplied claims and writes the entry; a review is called hands-on or Verified only when its reproducible test evidence is complete. Listings are free either way: aicoolies does not sell rankings, editorial recommendations, or removal from the Graveyard; sponsored placements are labeled and separate.
