Real time
Messages arrive in order, or say why not.
Delivery, sent, and read states are shown clearly. Messages sent while offline queue on the device and go out once the connection returns, without duplicates.

Chat app development company
Chat app development company, conversations that feel instant.
CodingMarble is a chat app development company that builds private messaging, group chat and support chat apps for Android and iOS, with a web admin for the team that runs them.
Real-time messaging is a small set of hard problems: delivery, order, notifications and moderation. We scope each one in writing, so you know what the first release carries and what waits for a later phase.
Yours
A private network instead of a borrowed platform.
Your own chat app means your own rules, members and data. You choose who can join, who can post and what is kept, within what the written scope defines.
Grows in steps
Start with text, add media and calls later.
A first release can be text, images and groups. Voice notes, video calling and bots are added as separately quoted phases once people are actually talking.
Messaging core
How a chat app works behind the screen.
A chat app keeps a live connection between each phone and a server. When you send a message, the server stores it, delivers it to the recipient, and pushes a notification if the app is closed. We build this with WebSockets on a custom Node.js back end.
Group chats, typing indicators, image sharing and message history follow the same pattern. Each is a defined feature in the scope, and hosting size is planned for the number of users you expect at launch. Hosting is sized in the scope, so cost stays predictable as members grow.
- Live delivery over WebSockets
- Push notifications when the app is closed
- Message history stored on the server
- Images and files with size limits
Apps like WhatsApp
What an app like WhatsApp actually takes to build.
The cost of an app like WhatsApp depends on which parts you copy. One-to-one and group text is achievable in a scoped project. End-to-end encryption, status stories, large-scale voice and video calling, and millions of users are a different scale, and are quoted separately. We explain that trade-off plainly.
Most businesses do not need a public messenger. A community chat, a customer support inbox, a team channel or a member-only network is smaller, cheaper to run and easier to moderate, and it can still be branded as your own app. That focus keeps the first release honest.
- One-to-one and group text first
- Encryption and calls quoted separately
- Community, support and team chat
- Branded as your own app
Chat and business
Connect chat to your customers and your website.
Chat is most useful when it is attached to something. A support chat can link each conversation to a customer record, and a marketplace can let buyers message sellers. WhatsApp Business API integration and chatbot replies can be scoped where a WhatsApp presence matters. Each link is a named item.
Automated replies and AI assistants are built on approved third-party providers, with usage fees paid by you at the provider’s rates. We describe what the bot may answer, what it hands to a person, and how conversations are reviewed. Nothing goes live until you have approved the wording.
- Customer support chat with agent inbox
- Buyer and seller messaging
- WhatsApp API and chatbot integration
- Human handover from automated replies
What is covered
What a chat app build can include.
Pick the messaging features your users need first. Heavier features are quoted as later phases with their own USD price.
Sign-in and profiles
Phone number OTP, email or social sign-in, with profile photos, display names and a contact or member list.
One-to-one and group chat
Text messaging, groups with admins, typing and read states, and message history that loads quickly on older phones.
Media and voice notes
Photo, document and voice note sharing with size limits, compression and storage planned for your expected volume. Compression included.
Push notifications
Notifications for new messages and mentions, with mute controls per chat, delivered through Firebase or Apple services. Quiet hours optional.
