Open-source AI visibility tools
Open-source AI visibility tools let you self-host your brand tracking and read the exact code behind every metric. It is a small, early space: Elmo is the most complete option, with a handful of smaller projects alongside it. If none fit, you can also script your own checks against the AI model APIs.
Why open source matters here
Most AI visibility tools are closed and hosted. You send them your prompts, and you trust the score they hand back. Open source changes both halves of that deal. You can read how a metric is built, and you can run the whole thing on your own infrastructure, so your prompts and history never leave your environment.
For a number that might land in a board report or shape a content budget, being able to audit it matters. So does owning your data outright, with no vendor holding your visibility history and nothing to migrate off if you decide to leave.
The open-source options
The honest picture is that this is a thin, early space. Elmo is the most complete open-source option, released under the MIT license with broad engine coverage. The other open-source projects we track are below. They are smaller and earlier, but they are real and worth knowing about.

Build it yourself: scripting AI visibility checks
If no existing tool fits, the underlying job is not complicated to script. Send your prompts to the model APIs, directly or through a router like OpenRouter, then parse each response for your brand name and any links back to your site. Store the results and repeat on a schedule, because a single run is a snapshot and answers shift over time.
The catch is everything around that loop. You have to cover enough engines, handle the ones without clean APIs, keep it running, and build some way to actually read the output. That upkeep is most of what you pay for when you buy a tool, or skip by self-hosting one that already does it.
Open source vs managed: the real tradeoffs
Neither path is free of cost. Self-hosting trades a subscription for your own setup and infrastructure. A managed tool trades transparency and control for someone else doing the work.
| Open source, self-hosted | Managed, paid | |
|---|---|---|
| Cost | No license fee. You pay for infrastructure and AI provider API usage. | A subscription, often metered by prompt or seat. |
| Setup | You deploy and maintain it yourself. | Sign up and start tracking. |
| Transparency | Read the code and verify how every metric is built. | The scoring is usually a black box. |
| Data ownership | Prompts and history stay on your infrastructure. | Your data lives in the vendor's dashboard. |
| Coverage and upkeep | On you, or the project's maintainers. | The vendor handles engine coverage and updates. |
/ FAQ
Frequently Asked Questions
- Is there an open-source AI visibility tracker?
- Yes. Elmo is an open-source AI visibility platform released under the MIT license, and you can self-host it for free. A few smaller open-source projects exist too, though the space is still early. For anything they don't cover, you can script your own checks against the AI model APIs.
- Can I build my own AI visibility tool?
- You can. The core loop is straightforward: send your prompts to the model APIs, directly or through a router like OpenRouter, parse each answer for brand mentions and citations, and log the results over time. The work is in maintaining it, covering enough engines, and running it at scale, which is what a finished tool handles for you.
- What is the best DIY way to track AI mentions?
- Define a small set of the questions your buyers ask, run them across the engines you care about on a schedule, and record whether each answer mentions or cites you. You can do this by hand for a quick read or script it against the provider APIs. Self-hosting Elmo gives you the same loop without building it yourself.
- Is Elmo really open source?
- Yes. Every line of Elmo is open source under the MIT license and available on GitHub. You can read exactly how each metric is collected and computed, self-host it on your own infrastructure for free, and export your data at any time.
