Codecov for Startups

When you are aggressively hiring developers into a high velocity development environment it's hard to get them onboarded, let alone confident enough to make changes to a rapidly evolving codebase.

How does Codecov help Startups?

A well tested codebase with code coverage requirements that are visible with every change to code helps new developers maintain a culture of coverage, learn how to write tests, and get more comfortable making changes to code without fear.

Improve Code Coverage by 30% in 4 Weeks

For organizations starting with coverage under 70% Codecov has historically been able to improve coverage by ~32% within 30 days.*

Maintain Code Quality on Growing Teams

Your team is constantly growing and evolving. Onboard new team members quickly and safely by putting in clear governance for coverage using Codecov’s coverage gates.

Coverage Gates

Onboard New Developers Faster, and With More Confidence

A well-tested codebase gives developers the confidence they need to quickly make changes without fear of breaking things. With a fast growing team it’s more important than ever to ensure developers feel comfortable making changes.

Organize Code Coverage As Your Team Evolves

As your engineering team grows and teams emerge around different parts of the codebase Codecov is flexible enough to adapt. Using Codecov’s flags you can organize and report on code coverage in a way that makes sense for your individual teams as well as your broader team.

@bvccaneer Haven't seen a good service that gets a quality score for Swift. Was tweeting about today and my hope that they might adopt Swift. I tried SQ a year ago and wasn't impressed. Also: Coverage != Quality. For Coverage use @codecov

Usually @codecov works pretty well for #Python test coverage, but I have also encountered "uncovered" .. comment / whitespace lines. Support is not responding, has anyone else seen this problem?

Hynek Schlawack


@ghickman Is there anything except coveralls and codecov? On GHA: Coveralls is pointless because their action doesn’t support Python coverage data and manual doesn’t work in forms (token). Codecov is super flaky period. I’ll prob move to conditional cov and fail if <100% on all versions

Any people running Python projects tried @codecov? Is it more reliable/sensible than @CoverallsApp?



@jengelberg @codecov I have successfully used the @codecov Python uploader to upload code coverage reports for Mac, Linux and Windows. Something which the Bash uploader cannot do. The Python uploader needs to be brought up to speed with the Bash uploader.

I highly recommend @GitHub Actions CI, it's way faster, easier and more intuitive to set up than Gitlab, Jenkins, or even Travis. How pull request overview and handling are great is well known, but you can see tests as well as code coverage report (thanks to @Codecov).#iosdev #CI

By contrast, I don't think code coverage services have an obvious default featureset. I personally like to see coverage trends, the ability to explore coverage, and context on tests. I lean towards codecov at the moment, but coveralls has advantages too.

Chris Withers


Anyone know of an alternative to @CoverallsApp? They're pretty unresponsive to issues, eg:

Fabian Franz


@ryanszrama @slimphp beats coveralls by far ... Comments just nerve, but @codecov gives nice report of coverage changing on a PR.

Yoshiya Hinosawa


Personally I don't think there is any reason to choose coveralls over codecov anymore now.



@codecov codecov is awesome. Just switched one of my projects from Coveralls to codecov. :-)


@yogurtphp codecov switched from coveralls to codecov updated travis-ci settings

Adam Rackis


Are there any reasons to pick coveralls over codecov? I tried both, and the quality was clearly better in codecov, on every metric I could see. Are they just newer, with some projects still on the older coveralls, or are there advantages I just wasn't seeing?

NLog .Net Logging


@ngeor @appveyor we use codecov instead of coveralls. No tokens needed, so less hassle (and works directly in forks) @codecov

So far, I’m liking the codecov interface much more than coveralls.

I'm trying #codecov for the first time and I must say that although I'm not a Coveralls pro user, Codecov UI is way better. I like it.

Fotis Gimian


If you're still on Coveralls, be sure to give @codecov a try, it's a much nicer experience. I'm migrating my projects over now! :)

Mikeal Rogers


@gr2m @izs i just had a case where the codecov report from lconv showed me something the coveralls UI didn't :(

Switched from Travis to @circleci, build triggers much faster. Also switched from coveralls to @codecov, the UI is much better.

I actually ended up switching from @codeclimate to @codecov Some explanations in this post:


tunnckoCore.eth 🇧🇬 • Sometimes Radical & Extreme


@lukeed05 @Smotko Cool. I really liked Codecov because nothing is needed -just this single line. While other services are needing manually add a repo, then get token & whatnot. Which is too many clicks & stuff when you open-source couple of repos per day. That's why I left Codeclimate before years

Nelson Correia


Loving the look of @codecov features! going to sub @codeclimate on next project to give it a try! #code #coverage

Alexander Popov 🔥


@proofit404 @_solnic_ @dry_py @codecov I'm using @codecov almost for all my OSS projects and I like it more than @codeclimate.

Paul D. 🇨🇦


@Numsigmernen BTW I don't have a preferred code coverage platform yet. I'm moving away from CodeClimate and have used Coveralls but the interface is pretty meh. Will take a look at CodeCov.

Juliana Gomez 🦋


@jahirfiquitiva @github @travisci @nodejs @reactjs we use @codecov and @codeclimate but tbh, code climate needs to be tweaked a lot because sometimes the code duplicate notifications get out of hand

Nelson Correia


@brynary @CodeClimate is superb! But I love how @codecov comments on Pull Requests w/ coverage summary & integrates w/ @GitHub commit status

Dalton Matos


@SonarQube @github - My biggest surprise when first using Sonar is that there's no separated checks for Pull Request coverage and (overall) project coverage. Even on you own screenshot it shows @travisci doing this. Every other tool I used had this: @codecov, @CoverallsApp and @codeclimate. 4/
