# Open Source AEO Projects & Resources

The open-source side of AEO/GEO is moving fast. This is the curated landscape — skill packs, frameworks, trackers, publisher-side tooling, and the academic work — for teams that want to build rather than buy. Star counts are a rough proxy for traction, not quality; pick on fit and license.

## Skill packs (Claude Code / Codex / Cursor)

Drop AEO/GEO audits and content workflows straight into a coding agent.

| Project | ★ | What it does |
| ------- | - | ------------ |
| [seo-geo-claude-skills](https://github.com/aaron-he-zhu/seo-geo-claude-skills) | 1,761 | 20 SEO + AEO/GEO skills for Claude Code, Cursor, and Codex. The category leader by stars. |
| [gtm-engineer-skills](https://github.com/onvoyage-ai/gtm-engineer-skills) | 961 | GTM + AEO agent workflows across 13 skill folders. MIT-licensed and clean to fork. |
| [codex-seo](https://github.com/AgriciDaniel/codex-seo) | 170 | Codex-first SEO suite: 26 workflows, 24 agents, DataForSEO / Gemini / Firecrawl integrations. |
| [ultraship](https://github.com/Houseofmvps/ultraship) | 103 | Claude Code plugin with 39 skills and 11 agents. Broader than AEO; useful ecosystem reference. |
| [claude-rank](https://github.com/Houseofmvps/claude-rank) | 34 | Tells you why your site will not get cited by AI, then fixes the issues it finds. |

## Frameworks & audit tools

The build-with-primitives layer below a managed platform like Clay.

| Project | ★ | What it does |
| ------- | - | ------------ |
| [geo-optimizer-skill](https://github.com/Auriti-Labs/geo-optimizer-skill) | 432 | Implements the Princeton KDD 2024 methodology — 47 checks across robots.txt, llms.txt, schema, entity coherence. The most academically grounded option. |
| [geo-optimizer (Go)](https://github.com/geo-team-red/geo-optimizer) | 218 | Pluggable AEO/GEO framework for embedding in Go services. |
| [eGEOagents](https://github.com/mverab/eGEOagents) | 111 | AEO/GEO skills for AI agents; pairs with Dust / Lindy / Relevance-style platforms. |
| [recomby-geo](https://github.com/recomby-ai/recomby-geo) | 101 | AEO/GEO "AI-employee" skill package with curated content. MIT. |
| [flow](https://github.com/AgriciDaniel/flow) | 41 | Evidence-led SEO playbook for the AI-search era, as 72 runnable workflows. |
| [geo-lint](https://github.com/IJONIS/geo-lint) | 22 | First open-source AEO/GEO linter — 92 rules; drops into CI. |

## Trackers (measurement)

Roll your own visibility measurement instead of buying it.

| Project | ★ | What it does |
| ------- | - | ------------ |
| [geo-aeo-tracker](https://github.com/danishashko/geo-aeo-tracker) | 132 | Local-first AI-visibility dashboard across six engines; the closest thing to a simple Profound. |
| [elmo](https://github.com/elmohq/elmo) | 113 | Open-source AI-visibility tracking. |
| [gego](https://github.com/AI2HU/gego) | 62 | Go-native tracker; schedules prompts across LLMs and does trend analysis. |
| [oneglanse](https://github.com/aryamantodkar/oneglanse) | 61 | Free, open-source AEO/GEO tracker across the major engines. |
| [xanlens](https://github.com/FayAndXan/xanlens) | 24 | Audit engine that asks real questions of seven AI engines — not static heuristics. |
| [ansvisor](https://github.com/aeohub/ansvisor) | 18 | Tracks ChatGPT, Google AI Overview, and Gemini. |
| [ai-visibility](https://github.com/sharozdawa/ai-visibility) | 6 | Explicitly framed as an open-source alternative to Otterly / AthenaHQ. |

## Publisher-side (make your site AI-readable)

A different play: serve crawlers and agents what they want.

| Project | ★ | What it does |

## Academic research (with code)

The peer-reviewed foundation. AEO/GEO was coined in Princeton and IIT Delhi's [KDD 2024 paper](https://arxiv.org/abs/2311.09735), which built the first benchmark and measured visibility lifts of up to 40%.

| Project | ★ | What it does |
| ------- | - | ------------ |
| [AutoGEO](https://github.com/cxcscmu/AutoGEO) | 152 | ICLR'26 framework that learns AEO/GEO strategies automatically, building on the Princeton paper. |
