Features for the way you work
What a custom web app is for
You need a custom web app when visitors and staff do different things, work with their own data and get results inside the service. The pages and features depend on your goal.
- 01
A service with personal accounts
Clients submit requests, see statuses, receive documents or return to saved data. Your team gets its own processing workflow.
- 02
A platform with user content
Members post entries, save materials and build collections. Editors review publications and manage sections by agreed rules.
- 03
A catalog or marketplace with special logic
Several groups of participants, their own access terms, selection by parameters, calculations and data exchange. Before development we work out how these actions connect.
- 04
A company portal and private sections
Materials, documents and requests in one place. Access for employees, clients and partners is defined separately for each scenario.
Search, materials and your own collections
A custom web app example
An example of an ideas service with search, themed materials and personal collections. You can open a card, save an idea and build your own collection.

Ideas service
Find, save and come back to what matters
Visitors find materials on a topic, study the cards and save what they like to a collection. The home page shows different ways to explore the service: search, ready-made topics and working with your own collections. You can try these actions in the example.
Project scope
What a turnkey custom web app includes
The specific sections, scenarios and integrations are fixed in the brief. We check both the screen design and how the agreed scenarios work.
Custom design
We design the main screens and states: lists, cards, forms, personal areas and error messages, and adapt the interface for phones.
User roles and permissions
We plan sign-in, personal areas and access to actions, and check that each user works only with the data they are allowed to, while your team manages its own sections.
Data and content
We build the agreed forms, statuses, search and content management. User content gets publishing and moderation by the project’s rules.
Integrations and notifications
We connect the chosen services and data exchange. The fields, events, limits and error handling are defined before implementation.
Testing, launch and handover
We test key scenarios and access, prepare public pages for indexing, deploy the project on the agreed infrastructure and hand over the code and access.
Users and access
Who can do what on the website
First we define who can view, create and change data. This helps agree on how the website behaves and test access before launch. Below is an example for a service with user content.
| Role | Main actions | Data access |
|---|---|---|
| Visitor | ActionsSearches and views public materials | AccessPublic sections and published cards |
| Member | ActionsSaves materials and keeps their own collections | AccessTheir own data and materials they are allowed to see |
| Editor | ActionsReviews publications and updates sections | AccessMaterials and features assigned to them |
| Administrator | ActionsManages settings and permissions | AccessData within the agreed authority |
Your website will have its own set of roles and permissions. Restrictions are enforced on the server; indexing settings solve a separate task.
Price and timeline
How much a custom web app costs
First version of the project
from $3,000
Timeline: from 30 business days
The starting point is $3,000 for a project with a limited, agreed set of scenarios. The cost of a custom web app is determined after planning, taking into account user actions, data, interfaces and integrations. The estimate separates the first release from later stages.
- Planning and an agreed set of scenarios
- Custom design and mobile screens
- Development, testing and launch
What the price depends on
- Scenarios and roles
The number of user groups, personal areas, statuses, data change rules and approval steps.
- Interfaces and data
The number of different screens and states, search, filters, forms, documents and materials.
- Integrations and migration
Exchange with external systems, availability of their APIs, and the volume and quality of data to migrate.
- Load and growth
Expected user activity, the amount of content, speed requirements and how updates will be made later.
The cost of a custom web app also depends on data migration, load requirements and external services. The domain, hosting, paid APIs and subscriptions are separate. Large platforms are estimated by project scope.
We plan the project in stages
First release and further development
Before development we decide which actions a user must be able to complete in the first version. This lets us estimate the work, launch an agreed scenario and then plan the next features.
- 01
The first release
We pick the essential actions and data — for example: find a material, open its card and save it to your collection.
- 02
Acceptance criteria
We fix the expected result, allowed roles, error states and checks, and use them to judge whether each scenario is ready.
- 03
Next stages
Additional sections and integrations are planned separately. The price and timeline of new tasks are agreed before the work.
Our approach
Why clients order custom web apps from MEISTERSTECH
We agree on the logic, show interim results and test the project against clear criteria.
Key scenarios that work fast
We use modern technology and choose how data loads for each scenario. We optimize images, code and requests and test the key screens on phones and under the agreed load.
- Optimized images and code
- Testing loading and actions on phones
- Checking performance under the agreed load
Clear project logic
User actions, roles and data rules are described before coding, and the main scenarios are shown on a wireframe.
Testing against the brief
We test access, forms, states and data exchange and agree which scenarios and load must be checked before launch.
Handover and growth
We hand over the code, materials and access as set out in the contract, explain how your team works with the website and plan support after launch.
Our development toolkit
Public pages and private areas
SEO essentials for a custom web app
A public part you can promote
A custom web app can have both public landing pages and private areas, and they need different rules. We plan the structure of the public part and how search engines access its content during planning.
SEO essentials are part of the agreed development scope. Further work on demand, content and promotion is planned separately.
Public pages that match demand
We prepare the section structure, URLs, headings, metadata and internal links. Important materials must be reachable through plain links.
Accessible content
We choose how public page content is rendered and check links and server responses, taking into account how the interface uses JavaScript.
Personal and system areas
Private data is protected by access checks. Personal accounts, system screens and internal search results get suitable indexing rules.
User content
We agree on how entries are published, moderated and exposed to search, and plan collection URLs and handling of duplicate, deleted and unavailable materials.
Additional scenarios
Web solutions for your project
A custom web app can be extended with separate tools. We choose the ones that help your users and team complete a specific task.
01
Web application development
A calculator, planner or another tool for regular work with data. It can live in a section of the website or grow into a standalone service.
02
3D applications
Interactive object viewing, visual selection or arranging elements. The scenario and data for the visualization are defined for your task.
03
Bots and automation
Notifications, collecting permitted data and scheduled actions related to the website. We agree on sources, events and the limits of external services.
04
AI assistant
A helper that finds answers in your company’s materials and guides visitors around the website. Sources, acceptable answers and handing questions over to staff are discussed separately.
For visitors to chat with your team, an online chat can be connected. Additional tools and their setup costs are agreed separately.
