Reviewed October 9, 2026 for 2027 planning. The plans below are current at the review date, not a prediction of what each company will offer throughout 2027. This is a comparison of published plan terms, not six hands-on tests.
A free builder can let you make an app without giving customers a dependable way to use it. For a small service team, the question is practical: can a customer submit a request, return to check its status, and see only their own records?
Define a Viable Free Build Goal
Use one small brief for every candidate: a service team's request tracker. A customer submits a request, signs in later to see its status, and staff update that status. A second customer must never see the first customer's records. Finally, the customer needs a stable link, not an editor preview.
This tests data, access, and publication. Use fictional records until permissions are checked. The best free no code app builder for this job is the one that passes those checks, not the one that produces the prettiest first screen.
What Counts as a Usable Free Plan in 2027
Trial, Forever-Free Tier, and Open-Source Option
A trial can show paid features that disappear. A free tier can change its limits. Open-source software shifts hosting, backups, and support to you. None means zero cost.
Separate editing, preview, public subdomain publishing, and publishing on your own domain. A "free ai app builder without coding" may offer only the first two. Searches such as "free ai app builder no code" and "ai app builder no code free" express a reasonable wish, but neither tells you whether customers can use the result.
HappySeeds - Start an AI-Built Web App With a Focused Free Test
What You Can Build Within the Current Free Allowance
HappySeeds fits a founder who wants to describe the customer journey rather than draw each screen. Its Free plan allows unlimited projects and publishing, with 30 credits on first login rather than a stated monthly refill. The free credits are the main constraints on building and revising the app. Use that allowance on the form, saved request, customer view, and staff update before polishing colors.
Test the access rule with two fictional accounts; conversation alone cannot prove it works.
Publishing Rules and the First Upgrade Decision
HappySeeds Free users can publish, and the number of projects is not capped. Preview links expire after 30 minutes, but that limit does not apply to the published URL. Share and test the published URL before inviting customers. Custom domains, code export, and GitHub sync remain features of applicable paid plans.
Bubble - Test Custom App Logic Before Paying to Go Live
Bubble Free includes a development version, API connector, one editor, 50,000 workload units monthly, and six hours of server logs. A live website begins on an eligible paid plan. Bubble suits difficult access or status logic, not a zero-subscription public launch.
A plausible list does not prove records are private. Try the tracker with a second account, and budget time to learn the logic and monitor workload.
Glide - A Free Workspace for Data-Driven App Experiments
A team with an existing requests table may find GlideOS a natural place to explore staff views. GlideOS Free currently lists two team members, ten projects, limited credits, and zero published apps or enabled workflows. Older Glide plan descriptions are not interchangeable with GlideOS.
This is a workspace experiment, not a customer portal. A polished interface will not repair a source table that exposes one customer's records to another.
Softr - Launch a Small Portal on a Free Subdomain
Softr is a direct fit for the shared portal-shaped brief. Its Free tier lists five app users, three builders, and 5,000 database records, and allows publishing on a Softr subdomain. A custom domain is paid.
The three builders can also use the app without taking any of the five app-user places. Count customers and other non-builder app users against that separate allowance. Inspect access with two accounts; a live link proves reachability, not privacy.
Adalo - Publish Free on the Web, Pay for Your Domain or App Stores
Adalo Free lists unlimited test apps, one editor, and 500 records per app. Its pricing grid shows zero paid "published apps" on Free, but the publishing FAQ permits Web apps on an Adalo subdomain. Do not mistake that for a custom domain or Apple and Google store distribution; those need eligible paid plans.
The free Web link can serve a narrow pilot. Check the record ceiling and staff edits; do not assume a free app-store listing.
FlutterFlow - Free Web Publishing With Paid Code Export
FlutterFlow Free includes Web publishing and up to two projects. Its Basic tier adds code download, custom-domain Web publishing, and one-click app-store deployment. That is a meaningful free Web test, but not a free source-code or native-release promise.
A published interface may still need separately configured data and authentication. FlutterFlow fits founders with technical help or an appetite for that build path.
Compare the 2027 Free Shortlist
Build Limits, Credits, and Project Caps
| Builder | Current Free allowance | Public Web on Free | Likely first upgrade |
| HappySeeds | 30 first-login credits; unlimited projects | Yes, published URL | More credits, own domain, or code/GitHub handoff |
| Bubble | Development version; one editor; 50,000 workload units/month | No live site | Live deployment |
| GlideOS | Ten projects; limited credits; two team members | No published app | Publishing or workflows |
| Softr | Three builders; five separate app users; 5,000 records | Softr subdomain | More app users or own domain |
| Adalo | Unlimited test apps; 500 records/app | Adalo subdomain | Own domain or app stores |
| FlutterFlow | Two projects | Web publishing | Code export or own domain |
These are plan limits, not observed build results.
Publishing, Branding, Domains, and Data
A vendor subdomain can serve invited users but is not your domain. Check branding, record limits, app-user counts, and whether you can retrieve data if you leave.
Upgrade Triggers and Ongoing Cost
Write the trigger beside the pilot: "We pay when user six needs Softr access" or "We pay before Bubble goes live." GlideOS needs an upgrade for publishing. HappySeeds Free can publish; more generation credits, a custom domain, or code handoff may be the reason to upgrade. Recheck every plan before purchase; October 2026 terms do not guarantee 2027 terms.
What You Can Realistically Launch for Free
A small Web pilot is plausible on HappySeeds, Softr, Adalo's subdomain, or FlutterFlow Web, subject to each limit and your own access checks. Bubble and GlideOS Free are better for building and evaluation. On HappySeeds, use the published URL rather than a temporary preview link.
Start with fictional records, two customer accounts, one staff update, and a support contact. This is more informative than a crowded demo.
When Paying Earlier Saves Rework
Pay before a real client depends on something the free tier cannot provide: a branded domain, enough user places, live deployment, or code handoff. For Softr, a builder using the app does not consume an app-user place; the relevant Free-plan trigger is a sixth app user.
The builder subscription is not the whole bill. Domain registration, email, payment processing, integrations, and support time remain. "Free app builder no code" is a starting condition, not an operating budget.
Trade-Offs and Exit Risks
The painful exit is losing request history or discovering nobody can reconstruct the access rules. Before storing real records, check export formats, downgrade behavior, connected accounts, and what happens to authentication identities. Code export does not necessarily carry data, secrets, or an independent hosting setup.
Keep a map of fields, roles, and status changes outside the builder.
How the HappySeeds Free Entry Point Fits
As a free no-code app maker, HappySeeds is worth testing when the bottleneck is turning a verbal workflow into a usable Web app. Spend its first-login credits on the request tracker and a meaningful revision. That tells you more than generating five polished home screens.
Free users can publish without a project-count cap. Test the published URL and the request tracker's access rules before inviting customers. If you need your domain, more credits, or GitHub handoff, compare the applicable paid tier. It is a distinct route, not an automatic winner.
Choose the Free Test That Answers Your Launch Question
Need a public link now? Start where the free terms clearly allow one, and test two-user privacy. Need to settle difficult logic first? A development-only tier may be enough. HappySeeds lets you probe the workflow through conversation and publish a Free pilot; test the published link and two-customer access rules before inviting anyone. The right free plan lets you learn something important before it asks you to pay.

FAQ
How can I check that customer A cannot open customer B's request?
Create two fictional accounts and one request under each. While signed in as A, try B's request link and ID directly, not just the visible list. Repeat on the published app. Hiding a row is not enough if its detail page still opens.
Can I diagnose a failed status update before upgrading?
Interrupt a test update and check three things: the error shown to staff, the status actually saved, and the logs available on your plan. If the cause cannot be inspected, define a manual way to confirm and correct uncertain updates before customers rely on the tracker.
Will the tracker stay available when a trial or AI credits end?
AI-building credits and access to a published app may have different rules. Check what the plan says about the live URL and saved records after a trial ends or a downgrade takes effect. If it is unclear, do not promise customers uninterrupted access.
Can customers receive a notification when their request status changes?
A working status page does not prove that email or other notifications are included. Check the free tier's automation and integration limits, then test one change with fictional contact details. If notifications are unavailable, tell pilot users how they should check their status.
What if two staff members update the same request?
Have two permitted staff users open one fictional request and submit different status changes. Check which value remains, whether either person sees a warning, and whether you can identify the final change. If the free tier cannot support that test, treat it as an unanswered rollout question.
