Flaky visual tests slowly destroy trust in a test suite.

You review the same diff again and again. Nothing changed.

We solved it in Argos:

If the same screenshot diff appears repeatedly across builds, Argos automatically ignores it.

Visual tests that start to heal themselves.

Came across a solid set of plug-and-play React components, and it even includes an MCP ✨

GitHub is the most unreliable service I have ever seen. Their SLA is crashing down so quickly 😱

• Jan: < 99.9% = down 10 min per week
• Feb: < 99% = down 1h 40m per week
• March: < 98% = down 3h 20m per week
• April: ?

Migrating Argos from Heroku to AWS Lessons and technical details from Argos’ move off of Heroku Postgres onto Amazon EC2 and RDS, and a playbook others can follow for large‑scale PostgreSQL migrations.

A cartoon depiction showing cloud servers, PostgreSQL icons, and an AWS logo, symbolizing database migration and cloud infrastructure.

One of the biggest engineering projects at Argos recently was migrating our 300GB PostgreSQL database off Heroku.

We accomplished this by building an EC2 bridge and replicating into RDS with two maintenance windows of 1 minute each.

I wrote a deep dive on the full migration 👇

Login interface featuring fields for username and password, alongside a SAML security icon and a green checkmark, indicating approval.

SAML SSO is now available on Argos Enterprise 🔐

If you’re a larger team, identity management isn’t a “nice to have.” It’s table stakes.

You can now:
• Authenticate via your IdP
• Auto-provision users on first login
• Enforce SAML across your team

From AI generated prototype to production Rust algorithm We asked an AI agent to design a diff mask fingerprinting algorithm, validated the approach, and turned it into a fast Rust module running in the core of Argos.

We shipped a new core algorithm in Argos from an AI agent draft → Rust → production.

Used for visual diff fingerprinting, now powering key features.

~3× faster than the TypeScript version.

Breakdown + code + benchmarks:

AI simplifies choosing relevant tests, making full suite runs on every branch unnecessary.

Introducing Subset builds in Argos: run partial tests while maintaining clear visual feedback. Ignored screenshots streamline reviews, and full runs on main still set baselines.

We just shipped a new thing: the Tests Dashboard. It gives a project-wide view of all tests, ranked by flakiness.

No more intuition or Slack archaeology to decide what to fix first.

If flaky tests slow down your reviews or CI, this makes the problem visible in seconds.

Shipping fast at scale without breaking production Pivot uses Argos from day one to ship fast with confidence, relying on visual testing with Playwright to protect their product with low test maintenance.

As co-founder of Argos, this is exactly why we built it.

Pivot chose Argos + Playwright from day one.
Screenshots over brittle assertions. Visual baselines as the contract.

Stable tests, regressions caught early, faster confidence to ship.

Visual Testing High-Precision Financial Charts with Playwright and Argos Finviz uses Argos visual testing on top of Playwright E2E tests to detect pixel-level regressions in high-definition stock charts across desktop and mobile.

Just published a customer story with Finviz.

For them, a one-pixel chart shift is a functional bug.

They use Argos with Playwright for pixel-level diffs in CI and PRs, with zero extra test maintenance.

Scaling Visual Regression Testing for the Component Ecosystem of MUI MUI uses Argos to protect the visual integrity of the most widely used React UI library, processing millions of screenshots per month across their component ecosystem.

Proud to share this one.

MUI runs visual regression testing at massive scale with Argos:
thousands of screenshots per build, millions per month, across OSS repos.

Fast PR feedback, low noise, real regressions only.

const obj = { a: 1, b: 2 };
const count = Object.keys(obj).length;

const obj = { a: 1, b: 2 }; const count = Object.keys(obj).length;

ECMAScript excitement 😉

Congrats to @bridgear.bsky.social @jordan.har.band on advancing Object.keysLength to Stage 2 at TC39 today 🎉

let count = Object.keysLength(o)

It counts the string-keyed own properties on an object. This avoids the cost of the intermediate array in Object.keys(o).length

Now you can capture accessibility trees alongside screenshots, perfect to spot text changes and catch accessibility regressions.

Flaky test detection is the first step in bringing full flaky test management to Argos. Visual testing is inherently flaky, but it doesn’t have to stay that way. Our goal is to give all teams the tools they need to understand, manage, and eliminate test flakiness.
