Amazon CodeGuru helps you automate code evaluations and enhance code high quality with suggestions powered by machine studying and automatic reasoning. You need to use CodeGuru Reviewer to detect potential defects and bugs which can be laborious to search out, and CodeGuru Profiler to fine-tune the efficiency of your functions primarily based on dwell knowledge. The service has been typically out there since June 2020; you may learn extra about the way to get began with CodeGuru right here.
Whereas working with many purchasers in the previous couple of months, we launched safety detectors, Python assist in preview, and reminiscence profiling to assist clients enhance code high quality and save hours of developer time. We additionally heard resounding suggestions on numerous areas such because the construction of pricing and language protection. We’ve determined to deal with that suggestions and make it even simpler to undertake Amazon CodeGuru at scale inside your group.
At this time I’m completely satisfied to announce two main updates for CodeGuru Reviewer:
- There’s a model new, simple to estimate pricing mannequin with decrease and stuck month-to-month charges primarily based on the scale of your repository, with as much as 90% worth reductions
- Python Help is now typically out there (GA) with wider suggestion protection and 4 updates associated to Python detectors
New Predictable Pricing for CodeGuru Reviewer
CodeGuru Reviewer permits you to run full scans of your repository saved in GitHub, GitHub Enterprise, AWS CodeCommit, or Bitbucket. Additionally, each time you submit a pull request, CodeGuru Reviewer begins a brand new code assessment and suggests suggestions and enhancements within the type of feedback.
The earlier pricing construction was primarily based on the variety of traces of code (LoC) analyzed monthly, $zero.75 per 100 LoC. We’ve heard your suggestions: As a developer, you’d like to research your code as typically as doable, create as many pull requests and branches as wanted with out eager about value, and maximize the possibilities of catching errors and defects earlier than they hit manufacturing.
That’s why with the brand new pricing you’ll solely pay a hard and fast month-to-month fee, primarily based on the whole measurement of your repositories: $10 monthly for the primary 100ok traces of code, throughout all linked repositories. And $30 monthly for every extra 100ok of code. Please word that solely the biggest department within the repository counts, and that vacant traces and feedback aren’t counted in any respect.
This worth construction not solely makes the price extra predictable and clear, however it should additionally assist simplify the way in which you scale CodeGuru Reviewer throughout completely different groups within the group. You continue to have the chance to carry out full repository scans on demand and incremental evaluations on every pull request. The month-to-month fee contains all incremental evaluations, and also you rise up to 2 full scans per repository monthly included within the month-to-month fee. Further full scans are charged $10 per 100ok traces of code.
Mainly you get all the advantages of Amazon CodeGuru and all the brand new detectors and integrations, however it’s as much as 90% cheaper. Additionally, you will get began for free of charge with the Free Tier for the primary 90 days, as much as 100ok LoC. When the Free Tier expires or in the event you exceed the 100ok LoC, you merely pay the usual charges. Take a look at the up to date pricing web page right here.
Let me share a couple of sensible examples (excluding the Free Tier):
- Medium-size repository of 150ok LoC: On this case, your month-to-month fee will get rounded as much as 200ok traces of code, for a complete of $40 monthly ($10 + $30). The variety of LoC is at all times rounded up. And by the way in which you possibly can additionally join a repository (or a number of) of as much as 50Okay traces of code (bringing the whole to that 200ok traces of code) for a similar worth. As much as 2 full scans are included for every repository.
- Three repositories of 300ok LoC every (the equal of a giant repository of 900ok LoC): On this case, your month-to-month fee is $250 ($10 for the primary 100ok traces of code, plus $240 for the remaining 800ok traces of code). As much as 2 full scans are included for every repository.
- Small repository of 70ok LoC, with 10 full scans each month: On this case, your month-to-month fee is barely $10 for the variety of LoC, plus $60 for the extra full scans (560ok LoC), for a complete of $70 monthly.
- Small repository with 50 energetic branches, the biggest department containing 10ok LoC, and 300 pull requests each month: Easy, simply $10 monthly. As much as 2 full scans are included for every repository.
The brand new pricing will apply beginning in April for brand spanking new repositories linked on April sixth, 2021, in addition to for repositories already linked as much as April fifth, 2021. We count on the biggest majority of use instances to see a substantial value discount. Until you could carry out full repository scans a number of instances a day (that is fairly an edge case), most small repositories as much as 100ok LoC shall be charged solely a predictable and reasonably priced payment of $10 monthly after the 90-day trial, whatever the variety of branches, contributors, or pull requests. Now you may develop and iterate in your code repositories — understanding that CodeGuru will assessment your code and discover potential points — with out worrying about unpredictable prices.

Python Help for CodeGuru Reviewer Now Usually Out there
Python Help for CodeGuru Reviewer has been out there in preview since December 2020. It permits you to enhance your Python functions by suggesting optimum utilization of information buildings and concurrency. It helps you observe Python finest practices for management circulate, error dealing with, and the usual library. Final however not least, it affords suggestions about scientific/math operations and AWS finest practices. These options are helpful for each learners and knowledgeable builders, and for small and huge groups who’re enthusiastic about code high quality.
With at present’s announcement of normal availability, you’ll discover 4 predominant updates associated to Python detectors:
- Elevated protection and precision for present detectors: Many Python finest practices have been built-in into the present detectors associated to plain library, knowledge buildings, management circulate, and error dealing with. For instance, CodeGuru Reviewer will warn you in case your code is creating a short lived file insecurely, utilizing float numbers as an alternative of decimal for scientific computation that requires most precision, or complicated equality with identification. These warnings will make it easier to keep away from safety vulnerabilities, efficiency points, and bugs basically.
- Improved detector for useful resource leaks: In the course of the preview, this detector solely targeted on open file descriptors; now it generates suggestions a couple of broader set of potential useful resource leaks corresponding to connections, classes, sockets, and multiprocessing thread swimming pools. For instance, you might implement a Python perform that opens a brand new socket after which neglect to shut it. That is fairly widespread and it doesn’t instantly flip into an issue, however useful resource leaks could cause your system to decelerate and even crash in the long term. CodeGuru Reviewer will recommend closing the socket or wrapping it in a with assertion. As a reminder, this detector is obtainable for Java as effectively.
- New code maintainability detector: This new detector helps you determine code points associated to points that normally make code bases tougher to learn, perceive, and keep, corresponding to code complexity and tight coupling. For instance, think about that you simply’ve spent a few hours implementing a easy prototype and then you definitely resolve to combine it along with your manufacturing code as is. Since you had been speeding a bit, this prototype might embrace an enormous Python perform with 50+ traces of code starting from enter validation, knowledge preparation, some API calls, and a last write to disk. CodeGuru Reviewer will recommend you refactor this code into smaller, reusable, and loosely coupled capabilities which can be simpler to check and keep.
- New enter validation detector: This new detector helps you determine conditions the place some capabilities or lessons might profit from extra validation of enter parameters, particularly when these parameter are more likely to be user-generated or dynamic. For instance, you might have carried out a Python perform that takes an surroundings identify as CLI enter (e.g. dev, stage, prod), performs an API name, after which returns a useful resource ARN as output. You haven’t validated the surroundings identify, so CodeGuru Reviewer would possibly recommend you implement some extra validation; on this instance, you might add a couple of traces of code to test that the surroundings identify is just not empty and that it’s a legitimate surroundings for this venture.
Please word that Python Help for CodeGuru Profiler continues to be in preview: CodeGuru Profiler permits you to accumulate runtime efficiency knowledge, determine how code is working on the CPU and the place time is consumed, so you may tune your Python software ranging from the costliest elements — with the objective of lowering value and bettering efficiency.
You may get began with CodeGuru Reviewer and CodeGuru Profiler for Python within the CodeGuru console.
Amazon CodeGuru is obtainable in 10 AWS Areas and it helps Python and Java functions. We’re wanting ahead to publishing much more detectors and assist for extra programming languages to assist extra builders and clients enhance their software code high quality and efficiency.
