# Which languages do you support?
# Which providers do you support?
GitHub and GitLab are fully supported at the moment. Bitbucket is supported for running analysis. Autofix and transformers for Bitbucket will be added in Q4 2020. Support for Azure DevOps, GitHub Enterprise, and GitLab Enterprise are in the works.
# Should I have to pay for open-source projects?
No. Part of our systems are built on Open-Source software. DeepSource is and will be free to use for Open-Source.
# What are the available modes of payment?
We use Stripe to process our payments. You can use a credit card to pay for both monthly/yearly plans. If you spend at least $10K per month, we can invoice you manually. Get in touch with email@example.com
# Is there a plan for students?
Yes, DeepSource is a part of GitHub Education pack, which means students get access to a DeepSource Pro plan completely free, including unlimited analysis on private repositories via GitHub. More details here (opens new window)
# Do you have plans for non-profit organizations?
After signing up, write to us at firstname.lastname@example.org and we will grant applicable credits to your account.
# Why do you require write permission for a single file?
When granting permission, we request access only to a single file -- that is
.deepsource.toml. With this permission, we can't write to any other file except the pre-defined
.deepsource.toml. We are working with providers like GitHub to make this clearer in their installation page.
You've got a couple of options.
