AI Developer Toolkit (developertoolkit.ai) is a learning platform for professional developers, sold as a one-time purchase for 12 months of access, with no subscription. Content is bilingual (English and Polish) and organized by tool and by level of the autonomy ladder — the /start/ and /ladder/ sections are free, no account required.
## Product and author
- [Pricing](https://developertoolkit.ai/en/pricing/): The Toolkit is $59.99 once: the Setup Pack for your stack, 12 months of 400+ guides and all eight books. Nothing renews on its own. 30-day refund on a first purchase.
- [For teams](https://developertoolkit.ai/en/services/): Up to 8 developers, one repository, one tool. The agent config, task template, test expectations and review checklist stay in your repo.
- [Setup Pack](https://developertoolkit.ai/en/setup-pack/): Nine questions, then your CLAUDE.md, AGENTS.md, Cursor rules, MCP config and TESTING.md — the Level 2 to 3 move, generated for your stack, installed in about 20 minutes.
- [Books](https://developertoolkit.ai/en/books/): All eight books ($383 at the median price of comparable ebooks): the Handbook, a book each on Cursor, Claude Code and Codex, and four role paths. In the Toolkit.
- [Examples](https://developertoolkit.ai/en/examples/): One walkthrough of the artifact chain, then the recipes: frontend, backend, databases, DevOps and mobile.
- [Contents](https://developertoolkit.ai/en/contents/): All 400+ guides in one list: Cursor, Claude Code, Codex, the Ladder, MCP, Skills, workflows and the cookbook.
- [About](https://developertoolkit.ai/en/about/): Who writes AI Developer Toolkit and why: the ladder from AI autocomplete to a software factory, in Claude Code, Codex and Cursor — by a CTO who ships with agents.
- [Developer Scorecard](https://developertoolkit.ai/en/scorecard/): A free 25-question scorecard that places you on the autonomy ladder, Level 1 to 4 — and names the one move that takes your workflow up a rung.
- [Tech Lead Scorecard](https://developertoolkit.ai/en/lead-scorecard/): A free 25-question scorecard for tech leads: the level your whole team ships at, across six dimensions — plus a 30/60/90 plan that moves it up a rung.
- [C-Level Scorecard](https://developertoolkit.ai/en/cto-scorecard/): A free 25-question scorecard on your org’s level — adoption and spend, shared infrastructure, quality gates, parallelism, ROI — with a 30/60/90 plan and a risk register.
- [MCP](https://developertoolkit.ai/en/mcp/): A public Model Context Protocol endpoint over 1100+ guides on Cursor, Claude Code and Codex. Two tools: search and fetch.
- [What's New](https://developertoolkit.ai/en/whats-new/): Level 5 of the autonomy ladder, the state of agentic engineering in 20

Claim my listing on Agent Web Map for developertoolkit.ai:
1. POST https://agentwebmap.com/v1/sites/developertoolkit.ai/claims and keep claim_id and claim_secret private.
2. Publish the verification line "AgentWebMap verification: <token>" (token from step 1) in https://developertoolkit.ai/llms.txt, or use the DNS, meta-tag or well-known method the response describes. This only verifies the listing; your website and domain remain yours.
3. POST https://agentwebmap.com/v1/sites/developertoolkit.ai/verify with {"claim_id": "...", "claim_secret": "..."}.
4. Save the api_key from the answer; it manages the listing (PATCH https://agentwebmap.com/v1/sites/developertoolkit.ai).
