A maintained list of 1,432 directories, launch platforms, registries and marketplaces that accept product submissions. 1,134 of them are free or have a free tier, and 192 are quick wins — free, low effort, and worth doing first. Every row shows cost, effort and priority, and links straight to the submission page.
Create an accessible, openly licensed handbook or course text with structured chapters, exercises, citations, and relevant links, then make the webbook public for directory discovery.
Curate a thoughtful public channel on local-first privacy, scam safety, or accessible-tool design, adding your tool only among diverse high-quality resources with original annotations.
Publish original sanitized essays on privacy engineering, safe document processing, or accessible product design, using your tool only as a relevant implementation example.
Start your small human-written lab notebook with original build lessons, accessibility fixes, and privacy experiments, linking to tools only when they support the post.
Launch a public-interest digital-safety community and publish substantial methods, reports, and tutorials with contextual your tool references.
Publish your original research, privacy or accessibility deck with useful citations and contextual links.
Apply with a code-heavy observability, Node, Ruby, Python, or Elixir tutorial using your real engineering problem as the case study.
Launch a consistent Trustworthy Tools digest that mixes independent sources with occasional relevant your tool research, adding original commentary to every selected link.
Send one current, technically substantive frontend or accessibility article/tool after publishing it, explaining the concrete reader value and disclosing your tool ownership.

Submit your founder-written product or privacy case study with concrete decisions, evidence, failures, and lessons for product practitioners.
Use your tool or founder social-web identity to publish original technical/privacy articles with relevant references.
Create your original engineering field-notes publication with human-approved privacy, accessibility, and local-first essays rather than republished marketing copy.
Create your publication or original Japanese engineering article with reproducible examples and contextual links to source or documentation.
Behind the list
Every row here starts as a line in a sheet, gets normalised into one of 15 groups, scored for cost, effort and impact, and written up with the steps to actually submit. The floor below represents that pipeline.
Open the sheet viewAn illustration of the AltF Backlinks floor: opportunities sourced at the back, vetted for cost and effort by the engineering pod, written up for outreach by the design pod, then tracked to placement along a line.
One-shot launches where timing and preparation decide the outcome.
Fast-growing listings specifically for AI-powered tools.
Extension, plugin and integration stores. Real review processes, real distribution.
Startup listings, beta lists and founder media.
General tool and software catalogues with real search traffic.
B2B review sites. Slow to approve, strong once live.
Package, image and docs hosting that carries real authority.
Showcases judged on craft. A good screenshot matters more than copy.
Write once, link back. Editorial standards vary widely.
Get quoted or distribute a release. Slower, higher ceiling.
Company and local listings. Unglamorous, consistently indexed.
Owned pages you control: company, founder, knowledge-panel entities.
Answer real questions. Never drop a bare link.
Brand surface and referral traffic more than link equity.
Everything that does not fit the buckets above.
