What makes BuildBear so powerful?
Automated Cloud Testing
Say goodbye to the hassles of manual testing. With BuildBear, your testing is automated whenever you make code updates. Enjoy effortless testing backed by detailed and actionable test reports.
Stress Test your DApps
BuildBear empowers you to effortlessly create an optimized testing environment for your DApp, ensuring precise testing in every conceivable scenario.
Keep Everything Private
BuildBear ensures the confidentiality of your DApp testing. Public Testnets are not built with privacy in mind, as the transparency of these networks exposes all contracts and transactions to public scrutiny, posing a potential risk to sensitive information.
Test as if you’re on Mainnet
Utilize BuildBear to conduct thorough Mainnet testing for your DApp, safeguarding against real-world consequences while troubleshooting potential problems.

"With BuildBear we were able to test the functionality, which, otherwise, would not be able to test for at least two more months. Incredibly accelerated our development process. Also, we had some issues regarding reading some events data, we updated BuildBear Team about it and guess what! They were blazing fast to look into the issue reported."

Rick van Melis

Smart Contract Developer

"Buildbear is a great proposition to us, as we absolutely require gelato to being able to operate so our protocol works as intended. We need the tasks to execute for correct behavior and additionally we need to have insights into the operation of our tasks so we can solve bugs, tweak executions, and fine-tune run frequency / operational parameters. So it is great to have all this combined in BuildBear."

"BuildBear Sandboxes are a godsend for anyone working with blockchain tech. The setup process is fast, taking minutes, and once done, everything just works. This service has been invaluable in my testing process, especially for mobile MetaMask insisting on https. I was able to obtain an HTTPS RPC endpoint effortlessly, eliminating the need for time consuming configs involving reverse proxies or setting up custom nodes on AWS."

"I've been trying all solutions available to emulate blockchain responses throughout my career, from running local nodes to all available online services and testnets. BuildBear comes out as the big winner for reacting exactly as things should once deployed on mainnet. It's been a relief and a huge time saver to work with the top product in its category. What these guys have created isn't easy - many of us have learned this the hard way."

"Having a GUI faucet and explorer is really valuable when testing contracts, it makes it so much easier to run tests and see the results. The BuildBear explorer made it trivial for us to isolate the root cause of the failing tests. The faucet is nice as well so that any user testing could get assets on their own, without having to ask us to provide test assets."
