Development & Technical covers the agents and infrastructure that developers use to build, run and extend AI agents. AI Platforms & Frameworks is the foundation: hosted agent environments, orchestration frameworks, multi-agent systems and protocol servers that connect models to tools and data. Development Environment and Model Services add SDKs, runtimes, model-serving engines and the plumbing for deploying agents at scale. Coding Assistance agents write, refactor, test and review code, from editor extensions to agents that work through a whole issue and open a pull request. Web Tools agents act on the internet: they browse sites, fill forms, scrape data and move information between web apps.
Choosing here is mostly an engineering decision. Check supported languages and models, whether you can self-host, and how the framework handles tool calls, memory, retries and observability once agents run in production. Look at the maturity of the project, including documentation, release history, issue response and license, since many entries are open source and some licenses restrict commercial use. For coding agents, confirm what access they get to your repositories and terminals and whether changes always go through review. For browsing agents, check how they handle logins and site terms, and keep them away from credentials they do not need. Costs usually come from the model calls an agent makes, so estimate token usage on realistic tasks.

A framework is a library you build with: it gives you building blocks for prompts, tools, memory and multi-agent coordination, and you host the result yourself. A platform is a hosted service that runs agents for you, usually with a visual builder, integrations, monitoring and billing included. Many products in AI Platforms & Frameworks offer both. Frameworks give more control; platforms get something running faster.
Give autonomy gradually. Coding Assistance agents can complete well-defined tasks such as fixing a failing test or updating a dependency, but they can also make wide, confident changes that are wrong. Run them in a branch or sandbox, require pull requests and human review, keep production credentials out of reach, and make sure your tests cover the code they touch before relying on them for larger tasks.
Most of the cost comes from model usage, which grows with the number of steps, the length of the context and retries when something fails. Run a few realistic tasks, log tokens per task, then multiply by expected volume. Add hosting, vector storage and any per-seat or per-run platform fees. Model Services tools that support caching, or smaller models for simple steps, can lower costs considerably.
Each agent gets one combined score. Popularity carries the most weight, measured by monthly visits to the agent's own website or by GitHub stars, since many projects in this group are open source. The score also reflects how many Development & Technical subcategories the agent covers and how often Creati.ai users save it. Each agent is listed once, only agents whose main focus is this group qualify, and advertising does not affect the order.
