  Emergent

  Price Free tier; Standard $20 / month, Pro $200 / month

  ★★★★★ Not rated yet

  Describes itself as an agentic vibe coding platform: a prompt becomes a deployed full-stack web or mobile app.

  Strengths

  • Deploys to a live URL with a custom domain and automatic SSL, no pipeline to set up
  • Web and Expo mobile apps come from the same platform
  • Code pushes to GitHub, and an existing repository can be imported

  Limitations

  • The stack is fixed, with no Flutter, Kotlin or Swift
  • Every deployed app draws 50 credits a month on top of the plan
  • Large gap between the Standard and Pro plans, at $20 and $200 per month

  Adalo

  Price Free plan; paid from $36 / month

  ★★★★★ Not rated yet

  Builds native iOS, Android and web apps from one visual canvas, with an AI assistant that builds and edits by prompt.

  Strengths

  • One project publishes as a native iOS app, a native Android app and a web app
  • Ada, the AI assistant, is included on every plan with no token or usage charges
  • Built-in relational Postgres database, so no external backend is required to start
  • Flat monthly price with no usage-based or per-action charges

  Limitations

  • The free plan can build and test but cannot publish an app
  • Published apps are capped per plan, so shipping several apps means moving up tiers
  • App store publishing needs paid Apple and Google developer accounts on top
  • Email support runs on a response-time SLA of three, two or one business days depending on the plan

  a0.dev

  ★★★★★ Not rated yet

  Turns a prompt into a native React Native app and ships it to the App Store and Google Play.

  Strengths

  • Generates a full React Native app and publishes it to the App Store and Google Play
  • Built-in monetization with subscriptions and one-time purchases
  • Convex backend and push notifications wired in

  Limitations

  • Primarily a mobile app builder: it generates native iOS and Android apps, with web as a secondary target
  • Output is React Native on Expo, so you work within that stack rather than a framework of your choice

  Zoho Creator

  ★★★★★ Not rated yet

  Low-code apps that ship with a native mobile app, scripted in Deluge, deployable to Zoho's cloud or your own servers.

  Strengths

  • Every app built comes with a native iOS and Android app, not only a responsive web view
  • Runs on Zoho's cloud, on AWS, Azure or Google Cloud, or on your own servers on-premise
  • CoCreator, powered by Zia, builds an application from a plain-language description
  • Payment fields are built in and route through pre-integrated gateways
  • ISO 27001, 27017 and 27018 certified and SOC 2 compliant

  Limitations

  • Zoho does not print figures on the pricing page, so plans can be compared by content but not by cost without asking for a quote
  • The Standard plan is limited to a single application; unlimited apps start at Professional
  • Custom logic uses Deluge, a scripting language specific to Zoho
  • AI model allowances and cloud function calls are capped per plan and per user per day
  • Which payment gateways are available depends on the data centre and the currency configured

  AppSheet

  Price Free for prototyping; paid plans from $5 / user / month

  ★★★★★ Not rated yet

  Google's no-code builder that turns a spreadsheet or a Gemini prompt into a mobile and web app.

  Strengths

  • Gemini app creation is included in every paid licence rather than charged separately
  • Starts from data a company already keeps, including non-Google sources such as Microsoft 365, Azure SQL and Salesforce
  • Core is bundled with most paid Google Workspace plans, so many organisations already hold the licence
  • Free tier has full platform access for prototyping with no stated time limit

  Limitations

  • Google cloud only, with no self-hosted option
  • Apps are not an exportable codebase, so leaving the platform means rebuilding
  • Enterprise data connections, machine learning modelling and the governance controls are Enterprise Plus only, and need a Workspace administrator account
  • Database row limits are tied to the plan, so heavier data pushes the tier up

  Xano

  MCP-ready

  Price Free tier; paid from $85 / month

  ★★★★★ Not rated yet

  A no-code backend that generates APIs over PostgreSQL, built to be driven by AI agents as well as by people.

  Strengths

  • Self-hosting on Azure, AWS, GCP or on-premise, not only the vendor's cloud
  • Frontend-agnostic: pairs with React, Flutter, Webflow, Framer, Lovable or Bolt rather than dictating one
  • An official MCP server, so external AI agents build against the same workspace rules

  Limitations

  • The first paid tier is $85 a month, a steep step up from the free one
  • It builds only the backend, so a second tool is needed for the interface
  • The free tier is rate-limited to 10 requests per 20 seconds and watermarks stored images

  Appsmith

  Price Free; Business $15 / user / month

  ★★★★★ Not rated yet

  Open-source low-code platform for admin panels and internal tools, self-hosted or on its cloud.

  WeWeb

  MCP-ready

  Price Free plan; paid seat and hosting plans are priced separately

  ★★★★★ Not rated yet

  Visual builder for Vue.js web apps, with code export, self-hosting and an MCP server for outside AI agents.

  Strengths

  • Exports the generated Vue.js source, so an app can be self-hosted and is not locked to the platform
  • Connects to Supabase, Xano, Airtable, Algolia, SmartSuite and any REST API, including internal databases without replication
  • Six documented authentication routes, from Supabase Auth and Auth0 to a custom token flow
  • Official MCP server, so outside agents such as Claude, Cursor or ChatGPT can build inside a project

  Limitations

  • Seat plan and hosting plan are billed separately, so the cost of a project depends on both
  • Code export and self-hosting require at least the Essential seat plan
  • MCP access needs a Pro or Partner plan once the 14-day trial on a new workspace ends
  • The MCP server does not expose plugin actions, so an agent cannot build with the Xano or Supabase plugins
  • It builds the front end and expects a backend such as Supabase or Xano alongside it

  OutSystems

  Price Free Personal Edition; OutSystems Developer Cloud quoted by the vendor

  ★★★★★ Not rated yet

  Enterprise low-code where Mentor generates the data model, logic and screens from a prompt or a requirements document.

  Strengths

  • Mentor generates a complete application, data model and server logic included, from a requirements document rather than only from a chat prompt
  • Shows a visual blueprint and asks for sign-off before applying changes, instead of building unseen
  • Runs on containerised .NET Core with Kubernetes, managed Aurora PostgreSQL and built-in CI/CD, monitoring and tracing
  • Free Personal Edition for up to 100 internal users needs no credit card
  • Self-hosting is available, unlike most tools in this category

  Limitations

  • No published prices at all, so every evaluation starts with a sales conversation
  • Pricing is metered on Application Objects and user counts, which makes cost hard to predict as an app grows
  • The Personal Edition is a development runtime only and cannot run production apps
  • Self-hosting, 24x7 support, higher uptime and SOC 2 or PCI DSS compliance are all paid add-ons rather than part of the base subscription
  • Base support is 8x5 business hours

  • Self-hosting is available on every tier, the free one included

  ★★★★★ Not rated yet

  Turns a chat prompt into a native Swift, Kotlin or React web app you own the code to.

  • Rork Cloud gives an app a managed Postgres backend with no setup, and can be moved into your own Supabase organisation later

  Limitations

  • Native iOS is only on the Max plan, from $200 per month
  • The free plan builds web apps only, and projects on it are public
  • Google Play publishing is a manual App Bundle upload
  • Expo and React Native projects can no longer be created, so a shared codebase for both phones is no longer an option

  • Builds web and native mobile apps in a single editor
  • Generates a complete app from one prompt with the AI app builder, then lets you refine it

  Mendix

  Price Free tier; Standard from $1,090 / month

  ★★★★★ Not rated yet

  Siemens-owned enterprise low-code where Maia turns requirements into visual models rather than raw code.

  Strengths

  • Free tier with unlimited users and one environment per app, no credit card and no commitment
  • Runs on public cloud, private cloud, Kubernetes or on-premise, unlike most tools in this category

  • Apps publish REST with OpenAPI documentation as well as OData and GraphQL services

  Limitations

  • The step from the free tier to Standard is $1,090 / month, with no small paid plan in between
  • Cloud resources are billed on top of the subscription, so the listed price is not the total
  • Standard support runs 9 AM to 5 PM with a 99.5 percent uptime guarantee; 24/7 support, high availability and multi-region failover need the quoted Premium tier
  • Free apps sleep after about an hour of inactivity and are capped at 0.5 GiB of database storage
  • Apps deployed to Mendix Cloud are locked to PostgreSQL

  Microsoft Power Apps

  Price Free Developer Plan; Power Apps Premium from $22 / user / month

  ★★★★★ Not rated yet

  Describe an app to Copilot and Power Apps builds the Dataverse tables and screens behind it.

  Strengths

  • Central governance for environments, data loss prevention, access and auditing across the whole tenant
  • Free Developer Plan with Dataverse for learning and non-production work

  Limitations

  • Microsoft cloud only, with no self-hosted option
  • What gets built is not an exportable codebase, so leaving the platform means rebuilding
  • Copilot app generation depends on Dataverse access and is limited by region availability
  • Priced per user per month, so cost tracks how many colleagues run the app rather than how many apps exist

  Quickbase

  Price From $35 / user / month

  ★★★★★ Not rated yet

  No-code operational apps with tables, reports and pipelines, plus Pave, which builds an app from a description of the work.

  Strengths

  • Pave builds a working app, data model and permissions included, from a description of the existing process
  • Governance is part of the platform: roles and permissions, encryption, audit logs and data classification
  • No-code connectors to Salesforce, Jira and ServiceNow, plus JSON REST APIs
  • Code pages allow custom HTML, CSS and JavaScript where the no-code builder stops
  • Quickbase states that customer data is not used to train the AI

  Limitations

  • The published per-user price excludes a platform minimum that is not published, so the real cost needs a quote
  • AI capability beyond Pave, namely the AI agent, Data Analyzer and AI Actions, is a paid Intelligence Package add-on
  • Single sign-on, SCIM provisioning, a sandbox and FDA and HIPAA compliance require the Business plan
  • All users in an account must be on the same plan, so one requirement can lift the whole account a tier
  • Platform analytics and solutions APIs are restricted to Enterprise
