In another you might build and push Docker images, and in yet another, you'd create ephemeral review environments. Once a change is reviewed, it can be immediately deployed to users using your existing deployment pipeline. After you've configured your stack once within webapp.io, you can make 10 copies instantly and run all of your end-to-end and acceptance tests in parallel.

    Reviewable

    Reviewable

    You've found the right code review tool. Tracks where par­tic­i­pants stand on each dis­cus­sion, en­sur­ing it won't dis­ap­pear un­til re­solved. Fully cus­tomiz­able logic de­ter­mines when a re­view is com­plete. Clearly shows net deltas since last time you looked, even if com­mits got re­based or amended. Batches com­ments and cor­rectly threads email re­sponses. Works only with GitHub and GitHub En­ter­prise, mak­ing for a seam­less in­te­gra­tion. Min­i­mal ad­min busy­work, no ex­tra fluff — just awe­some code re­views. In­stantly diff any two re­vi­sions of a file, in uni­fied or side-by-side style. Hide mi­nor changes: white­space, merge, and re­base deltas. Cus­tomize mar­gin, fonts, col­ors, key­board short­cuts, etc. Jump from a com­ment straight to the right spot in your fa­vorite ed­i­tor. Line com­ments map across file re­vi­sions and stay in place un­til re­solved, not just un­til changes are pushed. Mod­ern, clean UI with a touch of whimsy.

    CodeSonar

    CodeSonar

    CodeSecure

    CodeSonar employs a unified dataflow and symbolic execution analysis that examines the computation of the complete application. By not relying on pattern matching or similar approximations, CodeSonar's static analysis engine is extraordinarily deep, finding 3-5 times more defects on average than other static analysis tools. Unlike many software development tools, such as testing tools, compilers, configuration management, etc., SAST tools can be integrated into a team's development process at any time with ease. SAST technologies like CodeSonar simply attach to your existing build environments to add analysis information to your verification process. Like a compiler, CodeSonar does a build of your code using your existing build environment, but instead of creating object code, CodeSonar creates an abstract model of your entire program. From the derived model, CodeSonar’s symbolic execution engine explores program paths, reasoning about program variables and how they relate.
