02Cost & ROI Calculator

AI cost calculator and ROI calculator: work out the real cost before you commit

Three small calculators that run in your browser. Replace the example numbers with your own, because the answer depends far more on your volume and your time than on any vendor’s headline price.

The plan you would really need.
Example: a $24 server plus 20% for backups.
Updates, restarts, checking backups.
What an hour of your time is worth.
Install, secure and test it.

Result

Self-hosted cash cost
Self-hosted all-in cost (with your time)
Monthly difference (positive favours self-hosting)
Setup time as a cost
Setup pays back in
Most upkeep you can afford
12 months: subscription
12 months: self-hosted incl. setup

How to read this result

Cash cost is what leaves your bank account. All-in cost adds your upkeep hours at the hourly value you enter, which is the cost most comparisons leave out. The most upkeep you can afford is the number of monthly hours at which self-hosting and the subscription cost the same. If your real upkeep is above it, the subscription wins. This assumes both options do the same job, so check features and the licence first.

Everything you type stays in your browser. Nothing is sent or stored. Want the detailed version for one tool? Try the n8n Self-Hosting Cost Calculator, or read how much it costs to run an AI agent every month.

03Open-Source Directory

Self-hosted AI tools and open-source Zapier alternatives, by job

Each entry lists what it replaces, its licence, the hardware it needs and one thing to watch. The first nine entries come from my self-hosted software guide. The local AI entries summarise each project’s public description, so confirm details on the project’s own page before you rely on them, because licences and requirements change.

Automation

n8n

A visual workflow builder that connects apps, APIs and AI models. Run it yourself or use n8n Cloud.

Replaces
Zapier, Make
Licence
Sustainable Use License (fair-code, not an OSI open-source licence)

04Copy-Paste Workflow Hub

Free AI automation templates: prompts and workflow recipes you can copy

The prompts are written to work with any chat model, such as ChatGPT, Claude, Gemini or a local model. The four n8n files are importable JSON starters built from the recipes below, and I have not run them in a live n8n, so expect to adjust node settings and credentials on first import. These are starting points I wrote, not benchmarked or production-proven exports. I will label a template as tested only after I have run it and published the result. Replace the [BRACKETS] and {{variables}}, try each one on real examples, and keep a person in the loop before anything is sent or changed.

n8n workflow templates and recipes

  • Inbound email triage with a human approval step

    Untested starter Tools you could use: n8n, Make or Zapier, plus any AI model API.

    1. Trigger: a new email arrives in a shared inbox (IMAP or Gmail trigger).
    2. Send the subject and body to an AI model with the triage prompt above and ask for JSON only.
    3. Branch on needs_human. True goes straight to a person. False continues.
    4. Draft a reply with the reply prompt and save it as a draft, never as a sent message.
    5. Notify a person (chat message or email) with the draft and a link to approve or edit it.
    6. Log category, urgency and outcome in a sheet or database so you can measure how it performs.

    Guardrail: Nothing reaches a customer unless a person approves it.

    Main cost driver: Two AI calls per email times your monthly volume. Use the AI API cost tab with your real token counts.

  • Web form lead to CRM and alert

    Untested starter Tools you could use: Any automation platform, a form tool and a CRM or spreadsheet.

    1. Trigger: a form submission arrives by webhook.
    2. Validate the fields and remove duplicates by email address.
    3. Optional AI step: classify budget and urgency from the free-text field.
    4. Create or update the contact in your CRM or spreadsheet.
    5. Send a short alert with the lead summary to a chat channel or inbox.
    6. If any step fails, send an error alert instead of silently dropping the lead.

    Guardrail: Store only the fields you need, and say what the form is for on the form itself.

    Main cost driver: Mostly the task or execution count on your automation platform.

  • Weekly KPI digest

    Untested starter Tools you could use: A scheduler, a spreadsheet or database, and any AI model API.

    1. Trigger: a weekly schedule.
    2. Pull the numbers from a spreadsheet, database or analytics export.
    3. Calculate the changes in code or formulas, not with the AI model, so the arithmetic is exact.
    4. Give the model the calculated table together with the weekly summary prompt.
    5. Send the wording to email or chat with the table underneath it.

    Guardrail: Let code do the arithmetic and let the model do the wording.

    Main cost driver: One AI call a week, which makes this the cheapest recipe here.

  • Source monitor with a short summary

    Untested starter Tools you could use: An RSS or web trigger, a small data store and any AI model API.

    1. Trigger: a schedule or RSS feed for a short list of official sources.
    2. Remove items you have already seen by storing item IDs.
    3. Fetch the page text for each new item.
    4. Ask the model for three bullets and a list of claims worth verifying.
    5. Send the result to an inbox so a person reads the original source.

    Guardrail: Treat a summary as a pointer to the source, never as the source.

    Main cost driver: Grows with the number of sources times the number of new items, so set a daily cap.

09Our Digital Projects

What I build and maintain

So you can see the work behind the advice. More projects will be listed here once they are ready for visitors to use.

  • Beeznez Tech

    This site: cost breakdowns, buying guides and how-tos on AI and SaaS tools, written and maintained by one person.

  • n8n Self-Hosting Cost Calculator

    A stand-alone calculator that compares an n8n server with n8n Cloud, including your own upkeep time.

  • Guides hub

    The best starting articles on AI agent costs, small-business AI budgets and WordPress technical SEO.

  • Editorial Policy

    How articles are researched, how AI is used, what gets tested and how corrections work.

  • About the author

    Who builds and maintains these resources, and what he has actually built and run.

10Recently Updated Resources

Recently updated

The six most recently updated articles. I update an article when prices, licences or facts change, and I note the change on the article.

How this hub is put together

This page is a working index to the tools, calculators and guides on Beeznez Tech. I built it for founders, freelancers and small teams who want to use AI and automation without paying for more software than they need. The calculators run in your browser, the directory lists software I have written about or plan to cover, and the guides it links to show their arithmetic and their sources.

What is tested and what is not

Licence, price and hardware figures in the directory come from official documentation and are summarised in my guides, together with the date they were checked. The local AI entries are summaries of each project’s public description. The prompt templates and workflow recipes are starting points I wrote myself. I have not run them in production, so each recipe is labelled as an untested starter. When I run one and publish the result, I will change its label and link the write-up. My Editorial Policy explains how I research, test and use AI assistants, and what I will not publish.

How I choose what to list

  • A clear, published licence, so you can check whether your use is allowed.
  • A documented hosting requirement, so the cost can be estimated.
  • Relevance to small teams and solo founders rather than large enterprises.
  • No one can pay for a place in the directory.

Affiliate links and ads

This page contains no affiliate links today. If that changes, they will be marked and covered by the Affiliate Disclosure. The site may show Google ads, as described in the Privacy Policy, and ads never influence what is listed.

Corrections and suggestions

If you spot an outdated price, a wrong licence or a broken link, please contact me and I will correct it and note the change. If a tool or template is missing, tell me that too.
