CrabTalk vs Netlify.
Functions + site deployment
Netlify deploys serverless functions alongside a website, with data services and MCP hosting patterns. CrabTalk hosts reusable Rust/Wasm tool services with their own SQLite database and per-call memory reservations.
Which fits your work?
CrabTalk
- Tools reused independently of a website deployment
- Memory budgets of a few MiB per call
- A shared SQLite service for agents and applications
Netlify
- Functions sharing an existing website codebase
- Framework deployment previews and rollbacks
- Netlify data services and site integrations
Use both.
A Netlify function can call a CrabTalk service over HTTP for a reusable backend operation. Keep its API key in server-side configuration and apply the website’s visitor authorization before making the call.
Capabilities side by side.
| Capability | CrabTalk | Netlify |
|---|---|---|
| Deployment | Independent service or template copy | Functions versioned and deployed with the site |
| Memory sizing | 1–128 MiB per tool budget | Functions default to 1 GB; eligible plans allow increases |
| Input-specific budgets | Lower one running call’s reservation in code | Configure function allocation |
| MCP | Hosted service discovery and calling | Deploy an MCP handler as a function |
| Persistent data | SQLite belongs to the service deployment | Netlify Database, Blobs or connected storage |
| Recurring work | Cron tools and scheduled wakes | Scheduled and background functions |
| Compute billing | Runs, CPU and reserved memory-time | Function memory-duration through plan compute usage |
Add a stock-check tool to a storefront.
A website and an agent need the same stock result. Keep an existing inventory backend when it already supplies the operation.
CrabTalk
- Use an available inventory service or deploy custom tools
- Set tool access and per-call budgets
- Connect the agent and the website’s server-side function
Netlify
- Add the handler to the storefront project
- Query the existing database or connected store
- Deploy the function and any MCP route with the site
CrabTalk vs Netlify pricing.
CrabTalk
Hosting owners pay runs, CPU, reserved memory-time and rows. A small reservation reduces memory charges during API waits, and code can lower it once.
Netlify
Credit-based plans meter function compute in GB-hours from configured memory and invocation duration. Site requests, deploys, bandwidth and data products may also consume usage; legacy plans differ.
Netlify is outside our calculator. Include the website’s plan and data services, and use the applicable credit-based or legacy function rates for the workload.
Limits that affect the choice.
- CrabTalk tools have at most 100 ms CPU and 128 MiB memory per budget. A full framework function may rely on runtime capabilities it cannot use unchanged.
- Netlify documents a default 1 GB function allocation and increases up to 4 GB on eligible credit-based plans. These are provisioned settings, not measured live usage.
- CrabTalk does not replace the site build, CDN or preview workflow. Compare the backend tool operation while preserving the website services you still need.
Questions about CrabTalk and Netlify.
Can Netlify host a custom MCP server?
Yes. Netlify documents deploying an MCP handler at a site endpoint. Its infrastructure-management MCP server is separate from the application tools you publish.
Does every tool need a new database?
No. A Netlify function can reuse the application’s current data source. Choose a separate CrabTalk service database only when that service should own distinct records.
How can my website protect its CrabTalk API key?
A server-side Netlify function can hold the key and apply your application’s visitor authorization before calling CrabTalk. Do not embed a secret API key in browser code.
