# Open source alternatives to GTM tools, built on looot The code is MIT open source. The data is not free and not self-hosted: every real run calls looot and pays per call at the catalog price shown before the run. Each repo rebuilds one go-to-market job, such as finding the technologies a website uses or scoring leads by fit. You run the code. looot supplies the data. ## Short answer These are MIT-licensed repos in the loootai GitHub organisation. Each one rebuilds one go-to-market job on top of looot, with a demo mode that needs no account. You run the code yourself. The data comes from looot and is paid per call at the catalog price shown before every run. ## Repos with a page - looot-techstack (/open-source-alternatives/looot-techstack): Ask several providers what a domain runs on and see their answers side by side.

A run costs the sum of its looot calls at the catalog price. - Every repo shows a quote before it spends anything, and enforces a spend cap you set. - Failed calls are not charged, and a call that is still running is stored as pending, not as failed. - Demo mode and the dry run need no looot account and cost nothing. ## What are these open source alternatives? They are public repos in the loootai GitHub organisation, each licensed MIT. Each one rebuilds a single go-to-market job, such as technology lookups, lead scoring or competitor ads, on top of looot's data endpoints. ## Are they free? The code is free. The data is not. Every real run calls looot and pays per call at the catalog price, which each repo quotes before it runs. Demo mode and the dry run cost nothing and need no looot account. ## Do I need a looot account to try one? No. Each repo with its own page has a demo mode with made-up data that needs no token. A real run needs a looot token with four scopes and a funded balance. ## Do they match the paid products they rebuild? We make no claim of parity, quality, coverage or accuracy. Each page says what the repo does, where its data comes from and what it does not do. Compare against your own needs before you switch. ## Do I have to host them myself? Yes. You run each one on your machine or your own server. Several keep their state in a local file and have no sign-in, so put them behind your own access control if you host them. ## Is there an open source CRM? looot-crm is an open source CRM for a small sales team with companies, people, a pipeline board and an intent tab per account. twenty-app-looot adds looot lookups to Twenty CRM. Both are listed on this page. ## Is there an open source Zapier alternative? looot is not a workflow tool. n8n and Activepieces are open source workflow tools, and looot has an n8n node and an Activepieces piece that call its data endpoints from a workflow. Both are listed on this page. ## Can an agent run these repos? Yes. Each page has a prompt you can give your agent along with the setup link https://looot.ai/skill.md. The repos ship skills that run a dry run first and never raise the spend cap on their own. ## Last read 2026-10-11. Facts come from each repository on GitHub.
