Migrate from Flask to React + Go
Has a small Flask website or API grown into a service with many extensions and manual settings? We rebuild user journeys in React and agreed server modules in Go, verifying data, integrations and existing API behavior.
What teams build with Flask
- Small websites and REST APIs
- SaaS prototypes and MVPs
- Internal panels and integrations
- Web interfaces for Python scripts
Platform vs our custom development
| Parameter | Flask | Our development · React + Go |
|---|---|---|
| Architecture | Audit coupling between UI, computation and server logic | Separate React screens, Go API and calculation services |
| Long operations | Audit workers, timeouts and job execution | Queues, task status and controlled retries |
| Reliability | Find failure causes in the current application | Workflow checks, metrics and error monitoring |
What holds your project back
The team assembles the architecture
Flask leaves ORM and other architecture choices to the team. As auth, migration and admin extensions accumulate, compatibility and maintenance need consistent project rules.
A long request occupies a worker
In Flask's standard WSGI model, one request occupies one worker. Async views allow concurrent I/O within that request but do not by themselves increase the number of requests served concurrently.
Extensions and background work need checks
Older extension decorators may not support async views. Tasks spawned inside such a view can be cancelled when it finishes; reliable background work needs separate execution.
What you gain after migration
Interface for real workflows
We design React screens, mobile layouts and customer accounts around daily work, including loading states and clear error handling.
Clear API and computation boundaries
We move agreed modules to a Go API and long jobs to a queue. Valuable Python models and calculations can remain separate services.
Reliability checks before switching
We verify authorization, data and integrations and measure response time and load on your workflows. Success is measured, not assumed from a language choice.
Maintainable code handover
We deliver the repository, documentation, key operation tests and startup instructions, plus logging and error monitoring.
Management tools for your team
We agree on the features you need and connect the services you already use.
Accounts and access control
We agree on roles, actions and data access for staff and customers.
Jobs and computation results
Users see progress, errors and saved results for long operations.
Management and integrations
We build team workflows and connect existing external services.
Migration process
We verify data and workflows before switching to the new system.
Python application audit
Map data, dependencies, roles, APIs and jobs. Measure problem workflows and document behavior that must remain compatible.
Module-by-module migration
Build the React interface and Go API in staging, retain useful Python services and compare data and integrations with the live version.
Verification and switchover
Check load, access and workflows, synchronize recent data and agree on a switchover window and rollback plan. Public pages also receive URL and SEO checks.
