Sources and comparison notes
Bolt includes hosting and database features, and supports importing GitHub projects. For a move, review your database, authentication, and server functions alongside the source code.

PRICING
What drives the cost.
Bolt.new
Build tokens plus hosting allowances
Building uses tokens. Published sites have separate, account-wide hosting allowances and spending controls.
Bolt billing and subscriptions (opens in a new tab)Adios · Starter
$10/month
- 1 vCPU and 1 GB RAM
- 10 GB storage
- 500K included AI tokens
- 500 GB included bandwidth
How costs add up
Bolt.new
Bolt subscriptions include a token allocation for building. Hosting has its own usage allowances, so development activity and traffic to the finished application need separate estimates.
- Estimate how actively you will iterate on the project, then check the current subscription's token allowance and renewal rules.
- Review account-wide hosting limits and any additional-usage spending cap across all published sites.
Adios
Apps must fit within plan resources. The free workspace supports development and previews with your own AI provider key; production apps require a paid plan. Include external services in your estimate.
Plans and allowances ↗For an agency, compare an editing-heavy month across several projects with a month when published sites mainly receive traffic. Include backend services and external API costs, and do not assume a token on one platform has the same cost or effect on another.
A CLOSER LOOK
Technical details & migration.
Start with the supported backend stack
Bolt.new
Bolt supports JavaScript-based backends such as Node.js. Its documentation excludes Python and PHP backends from the supported development environment. That boundary matters if you already have a service to bring, even when the frontend looks similar.
Adios
Adios configures the application's runtime and build and start commands in a manifest. A frontend and a separate backend can have distinct service definitions and resource needs. Check the runtime and dependencies your existing project actually requires.
Adios documentation ↗A new JavaScript app and an existing Python API are different starting points. Choose around the code you need to run, not only the speed of generating the first screen.
Code access and backend services are separate
Bolt.new
Bolt can import GitHub projects, sync changes, and work with branches. Bolt Database separately provides authentication, storage, logs, secrets, and server functions. Repository access does not, by itself, reproduce those managed services on another host.
Adios
Adios supports source review and Git workflows alongside configurable application and data services. You can keep an external backend or build your own, but must explicitly supply connection settings, application authentication, and any required worker logic.
Adios documentation ↗Review one complete feature, such as an authenticated file upload: the UI, user identity, access rule, storage location, and server function all need to work together after a move.
Publishing is the start of the usage model
Bolt.new
Bolt hosting has bandwidth and request allowances shared across the account. Paid subscriptions include Pro hosting, with spending controls for additional usage. Sites can pause when the applicable allowance or spending cap is exhausted.
Adios
Adios production plans specify compute, storage, bandwidth, and AI allowances. The free workspace is for development and previews; production applications require a paid plan. Size the app and its dependencies against those resources.
Adios documentation ↗Test the expected traffic pattern, not just whether the Publish button works. A campaign landing page and a frequently used authenticated app can have very different request and bandwidth profiles.
Which fits my project?
A new JavaScript web app
Consider Bolt
Bolt's supported stack, AI editor, GitHub integration, and built-in publishing can fit a browser-first development workflow. Validate the backend requirements as well as the interface.
A frontend with an existing non-JavaScript API
Consider Adios
If the backend needs its own runtime and deployment process, assess Adios's service configuration. Preserve the existing API contract while deciding how the frontend should be developed.
Several published client sites
Model aggregate usage
Bolt's hosting allowances apply across the account. Estimate combined traffic and building activity, then compare that with the total capacity and services your Adios projects would require.
Recommendations by Adios, based on the documentation linked above.
Moving from Bolt.new to Adios
Start from the repository, then decide what happens to the connected backend. Treat database and identity changes as their own workstream.
Capture a working repository revision
Use GitHub integration to establish the source baseline. Record package scripts, environment variables, deployed URLs, and the user flows that need to remain unchanged.
Inventory backend connections
Identify Bolt Database or Supabase usage, authentication, storage, secrets, and server functions. Decide which connections stay in place and which services will be replaced.
Configure and test the Adios services
Add the appropriate build and start commands, health checks, resource settings, and secrets. Adapt functions that depend on a managed environment before expecting them to run as application code.
Validate data access before the domain move
Test login, authorization, uploads, webhooks, and database writes. If moving data, rehearse export and restore, then coordinate final writes and the domain switch with a rollback plan.
Suggested steps, not an automatic importer. Rehearse before changing production.
BEFORE YOU CHOOSE
A few useful answers.
Can I use Bolt to build a Python or PHP backend?
Bolt's supported technologies documentation specifies JavaScript-based backends, including Node.js, and excludes Python and PHP backends. For an existing backend in another language, assess whether it stays external or needs a platform with a suitable application runtime.
Does Bolt support importing an existing GitHub project?
Yes. Bolt supports importing repositories, syncing changes, and working with branches. Review the supported technologies and backend dependencies of the imported project; repository import alone does not make every application stack compatible.
Are Bolt hosting allowances per site?
Bolt documents hosting allowances across the account. When estimating capacity, include all published sites and review additional-usage controls. Development tokens and live hosting usage are separate things to budget for.
