Numbers move. Before you promise a client “unlimited,” screenshot the vendor’s pricing page.
What “free” should mean for your first app
Free is a strategy, not a personality trait. I use free tiers to prove behavior: will someone schedule a call, submit a form, or complete a workflow five times? If yes, I happily move money to hosting, domains, and paid rows. If no, I do not upgrade my way out of a bad idea.
The tools below differ in where friction appears. Glide hits row ceilings. Bubble hits branding and production deployment. Airtable hits record counts. None of those limits are moral failures—they are guardrails that keep infrastructure subsidized for learners.
1. Bubble (free development)
Why it is on this list: Bubble’s free side is not a toy demo—it is where I learned privacy rules, repeating groups, and API workflows without gambling rent money.
What you get: A real development environment to build responsive web apps, model a database, and simulate user flows. You can go surprisingly far before you pay.
What you do not get: A polished production story without trade-offs—expect Bubble branding and platform limits around going live at scale. Treat free Bubble as school and prototype, then budget roughly $32/month and up when you need production-grade hosting and capacity.
Best first project: A two-role web app—admin and customer—with five screens and fake payments stubbed as status fields.
Watch-out: Performance habits start on day one. Do not train yourself to “search everything every time.”
2. Glide (free)
Why it is on this list: Glide turns a spreadsheet into something people will actually tap on their phones. The free tier is one of the fastest “moments of wow” in no-code.
What you get: App layouts, basic actions, and enough polish that non-technical stakeholders believe you.
What you do not get: Generous headroom on rows, monthly updates, and users once real traction hits. Branding may appear on free apps depending on current policy.
Best first project: Internal request tracker, event RSVP, or partner directory backed by Google Sheets.
Watch-out: Row math matters. A “small” sheet explodes when every automation duplicates lines.
3. Softr (free)
Why it is on this list: If your brain lives in Airtable, Softr is the shortest path to a customer-facing portal without writing React.
What you get: Block-based pages wired to Airtable with authentication patterns that feel grown-up compared with pure site builders.
What you do not get: High record counts, many published pages, or white-label polish on the free end. Expect Softr branding on free projects.
Best first project: Client portal where each customer sees only their linked records.
Watch-out: Your Airtable base quality is your product quality—garbage in, garbage portal out.
4. Airtable (free)
Why it is on this list: Airtable is the stealth database for a generation of makers. Interfaces on free/low tiers let you ship operational UIs without a separate app server.
What you get: Relational tables, views, automations, and enough Interface Designer access to run real internal workflows on small teams.
What you do not get: Large record counts, heavy attachment history, and advanced governance without upgrading—Plus commonly lands around $20 per user/month annually when you need breathing room.
Best first project: CRM-lite with pipeline stages and an Interface for daily standup metrics.
Watch-out: Automations are addictive. Count runs before you chain seven triggers.
5. AppSheet (free for personal)
Why it is on this list: For individuals building tools for themselves—inventory at home, hobby projects, personal field logs—AppSheet can stay at $0 in personal contexts while teaching model-driven thinking.
What you get: Apps with forms, views, and offline-friendly patterns that beat a naked Google Form.
What you do not get: A free lunch for a 40-person company on regulated data. Business use typically intersects Google Workspace pricing—think ~$6–14 per user/month as a common Workspace band before you layer AppSheet licensing for serious org use.
Best first project: Inspection checklist with photos and a map view for a solo operator.
Watch-out: Enterprise expectations creep fast. Decide early if this is personal learning or company infrastructure.
6. Google Sites
Why it is on this list: Sometimes your “app” is actually a documented workflow plus links—and Sites is free inside Google accounts, dead simple, and fine for internal hubs.
What you get: Fast pages, access control via Google sharing, and zero design paralysis.
What you do not get: Relational logic, transactional backends, or mobile-app distribution. Pair with Google Sheets and Apps Script if you need light automation.
Best first project: Team handbook + request form links + embedded Sheet charts.
Watch-out: Do not mistake a Site for a database. You will regret billing logic in a static page.
7. Carrd (free)
Why it is on this list: Carrd is the fastest credible landing page on the internet. Free gets you a sharp one-pager for idea validation.
What you get: Clean templates, fast publish, and a free .carrd.co subdomain so you are not stuck in localhost fantasy.
What you do not get: Multi-page information architecture without Pro; advanced forms and widgets often wait behind paid.
Best first project: Waitlist page with a clear headline, three bullets, and one CTA.
Watch-out: If you need a blog or CMS, jump to Webflow paid tiers or a static site—see Webflow review when budget opens.
8. Notion (free)
Why it is on this list: Notion is not a replacement for Bubble, but it is a shockingly good operating system for early teams—docs, light CRM, project boards, and public pages.
What you get: Databases with views, relations, and templates that feel like software if you squint.
What you do not get: Hardcore enforcement, complex auth models, or mobile-store distribution. Paid Plus ~$10 per member/month and Business ~$15 unlock collaboration features teams eventually need.
Best first project: Founder CRM + content calendar + investor update log in one workspace.
Watch-out: Do not build financial transactions purely in Notion unless you enjoy audit anxiety.
Five mistakes I see on every free-tier project
-
Mistaking branding for failure. Users forgive *.carrd.co on a waitlist more than they forgive a broken signup. Ship.
-
Duplicating truth across three tools. Pick one canonical table—usually Airtable, Sheets, or Bubble’s DB—and let everything else read from it.
-
Skipping analytics. Even a free GA4 property or privacy-friendly Plausible trial tells you if anyone cares. Flying blind is expensive.
-
Over-automating before manual works. If you cannot fulfill ten orders with a spreadsheet and email, Zapier will not save you.
-
Buying seats before buying clarity. Notion Business at $15 per member/month adds up when half the workspace is empty philosophy docs.
Sample two-week sprint (still $0 core)
Day 1–2: Carrd landing + plain-language offer.
Day 3–5: Notion or Airtable intake form substitute + manual fulfillment.
Day 6–9: Glide or Softr self-serve view for early users (still you in the loop).
Day 10–14: Bubble only if logic truly outgrew sheets—otherwise tighten copy and distribution.
That sequence mirrors How to Build an MVP Without Code but optimized for broke-week energy.
The first dollars I spend after free
When revenue or conviction appears, I spend in this order: custom domain ($10–15/year), email on a real domain (often bundled with Workspace), then one paid builder tier that removes the bottleneck—usually rows in Glide, records in Airtable, or production capacity in Bubble ($32/month). I do not buy five tools at once. One unlocked constraint beats five half-open accounts.

How I would chain these for a real MVP
- Carrd for the promise in one screen.
- Notion or Airtable for the manual back office while humans do the work.
- Glide or Softr when users need self-serve views.
- Bubble when logic outgrows spreadsheets.
That sequence keeps you honest: you only graduate tools when pain appears, not when Twitter hype appears.
FAQ
Which free tool is the most “serious” for real apps?
Bubble on the web side—if you accept that free is for learning and staging, not stealth-scale production. For mobile-friendly data apps, Glide’s free tier often wins the demo.
Why not list Webflow as free?
Webflow’s Starter workspace is free to learn, but real custom domains and production hosting sit on paid site plans. When you are ready, budget ~$18–49/month depending on CMS and business features—details in Webflow review.
Do free tiers hurt SEO?
Subdomains and branding can dilute trust. For a public marketing site, I still prefer a paid domain and a builder meant for content.
When do I stop being cheap?
The day support tickets, data integrity, or uptime risk real money. Until then, free is rational.
