Community FAQ
Questions by product
ngrok FAQ
Can I self-host ngrok to avoid dependency on third-party cloud infrastructure?
No, ngrok does not currently offer an official self-hosted version. The service relies on its cloud infrastructure to establish and maintain secure tunnels, so you must use their hosted platform. However, some open-source alternatives like localtunnel or expose exist if self-hosting is a strict requirement.
Community insight informed by Reddit discussions
Does ngrok support offline functionality or local-only tunneling without internet access?
No, ngrok requires an active internet connection to establish tunnels through its cloud servers. It cannot create tunnels or expose local services without internet access since the tunnel endpoints exist on ngrok's public servers.
Community insight informed by Hacker News discussions
Who owns the data transmitted through ngrok tunnels and how is privacy handled?
Data transmitted through ngrok tunnels passes through ngrok's servers, so technically ngrok has access to the traffic. Ngrok uses TLS encryption for tunnels, but since it terminates the tunnel on their infrastructure, they could potentially access metadata or unencrypted data if not using end-to-end encryption within the tunnel. For sensitive data, additional encryption at the application layer is recommended.
Community insight informed by StackOverflow discussions
Are there any API limitations or rate limits when using ngrok's service programmatically?
Yes, ngrok imposes rate limits and connection limits depending on your subscription tier. The free tier has restrictions on concurrent tunnels, session duration, and API request rates. Pro and higher tiers offer increased limits and additional features. Detailed limits are documented in ngrok's official API documentation.
Community insight informed by Forums discussions
Is there a way to export or migrate existing ngrok tunnel configurations to another service?
Ngrok does not provide built-in export or migration tools for tunnel configurations. Tunnel setups are typically defined in local config files or via CLI commands. To migrate, you would manually replicate your tunnel definitions in the new service’s configuration format. Some third-party tools or scripts might assist with this, but no official migration path exists.

Postman FAQ
Does Postman support self-hosting to keep API data completely on-premise?
Postman does not offer a self-hosted version. All collaboration features and data storage are managed via Postman's cloud infrastructure, which means API collections and test results are stored on their servers. For teams requiring full on-premise control, Postman currently does not provide an option.
Community insight informed by Reddit discussions
How well does Postman work offline, and can I run tests without internet access?
Postman has limited offline capabilities. You can open and run existing collections offline, but features like syncing collections, team collaboration, and accessing shared environments require internet connectivity. Automated monitoring and cloud-based integrations also won't function offline.
Community insight informed by Hacker News discussions
What are the data ownership and export options for API collections in Postman?
Users retain full ownership of their API collections and can export them in JSON format at any time. This export includes requests, tests, and environment variables. However, some metadata related to collaboration and usage analytics is stored only on Postman's servers and is not exportable.
Community insight informed by StackOverflow discussions
Are there any API limitations when using Postman's API for automation and integration?
Postman's API allows programmatic access to collections, environments, mocks, and monitors but enforces rate limits depending on the plan tier. Free plans have lower request quotas, and some endpoints related to team management and advanced monitoring are restricted to paid plans.
Community insight informed by Forums discussions
What is the best way to migrate large Postman collections to another API testing tool?
The recommended approach is to export your Postman collections as JSON files and then import them into the target tool if it supports Postman format. For very large collections, consider splitting them into smaller parts to avoid performance issues during import. Note that some proprietary features like monitors or mocks may not transfer.
