A github rebase moves your feature branch commits to the tip of the main branch. You run this workflow in your pull request or local terminal to keep history clean. Engineering teams set up this process to avoid messy merge commits in shared codebases. Still, broad branch roles let users rewrite shared history and cause code loss.
How a github rebase works in your workflow
Version control tracks every code change as a separate commit in a tree. When two people work at the same time, their branches split apart. A standard merge ties those two branches back together with a new merge commit. That choice saves the exact timeline, but it makes the commit log hard to read.
Rebasing takes a different path to join your work with the main branch. The system finds the common starting point between your branch and the target branch. It sets your new commits aside for a moment. Then it pulls in the latest changes from the main branch first. After that, the system plays your commits back one by one on the top.
This process creates brand new commits with new identification hashes. Your feature branch now looks like you wrote it after the latest main updates. In the web interface, you can pick the rebase option when closing a pull request. The platform checks for file conflicts and places your commits straight onto the base branch.
Managing conflicts and force pushes
Sometimes two developers change the exact same line of code in different branches. When the system replays your commits, it stops at the conflicting file. You must open the file, pick the right code, and save the fix. Once you fix the conflict, the rebase continues to the next commit in line.
Because rebasing makes new commit hashes, your local branch will not match the remote branch. A standard push will fail because the remote server sees a split history. You have to force push your branch to overwrite the remote copy. Teams must never rebase public branches that other people use for active work. If you rewrite a shared branch, your teammates will face broken local histories.

What branch rules solve and what they miss
Platform admins set up branch rules to stop bad force pushes on important branches. You can block force pushes on the main branch and require pull request reviews. You can also force every pull request to use a rebase merge for a flat log. These rules control who can write code to specific branches in the repo.
Still, source control rules only check code before it merges into the main branch. They do not govern what happens when developers or scripts run commands against live servers. A clean git log does not stop a bad database query in a live session. Once an engineer logs into a server or database, git roles offer zero control. Teams still need a way to inspect live commands and mask sensitive data like emails.
Add runtime guardrails and masking beside your databases and APIs
Login rules, role grants, and CI checks govern who connects to your stack. Yet any allowed script, engineer, or AI agent still runs commands with the full scope of its role. For workloads on Postgres, MySQL, SQL Server, MongoDB, ClickHouse, Kubernetes, SSH, or internal HTTP services, hoop.dev sits inline in the protocol beside the service as an open-source proxy, a sidecar for your database or API. On every production query an agent or human runs, hoop.dev decides whether to pass, mask, block, or escalate it for review.
Before a query runs, hoop.dev guardrails check the statement against your rules, an AI Analyzer you configure can score intent or hold risky calls for human approval, and hoop.dev data masking rewrites sensitive fields in responses in memory. Explore the MIT-licensed project on GitHub.
Frequently asked questions
When should I use rebase instead of merge?
Use rebase on your private feature branch to pull in updates from the main branch. This keeps your pull request clean and easy for your team to review. Use a standard merge when you combine big shared branches where exact history matters.
Why did my commit hashes change after a rebase?
Git creates a commit hash from the code changes, the time, and the parent commit. When you move a commit to a new parent, the system must calculate a new hash. The code stays the same, but Git treats the replayed work as a brand new commit.
How do I recover from a bad rebase?
Git keeps a local log of where your branch pointers stood before the rebase started. You can read this reference log on your machine to find the old commit hash. Then you reset your branch back to that exact starting point to restore your files.
