For Tech Leads, SREs, and Engineering Managers
Sealens plugs into your repository, deploys and alerting tool. On each alert, it ranks the commits that shipped, most suspect first, with your team's last verdict on that alert. Before each release, it flags what already broke.
Why not just ask an AI assistant?
Triggered by your alerting tool. No one has to ask for it.
Each deploy is recorded next to your commits as it happens, so you can see what was live.
Once the incident resolves, one click in your channel records what broke. When the same alert fires again, it comes back.
Before you ship, commits touching code your team confirmed has broken are flagged.
Your tools start from production.
Sealens starts from your
repository.
It links the alert, the deploy and the error, when there is one, to the code that just shipped. It also reads a release before it ships, and keeps what broke, file by file.

One incident, start to finish: the ranked list, the cause you confirm, and what it changes for the next release.

Point Sealens to your codebase with read-only access (Security One-Pager). GitHub today, GitLab and Azure DevOps next. Private repositories supported.
Your alerting tool fires, Sealens analyses, and the ranked list lands in your Slack or Teams channel. Same before a release. You can also run one yourself on any past incident.
Once the incident resolves, Sealens asks in your channel which commit caused it, narrowed by the fix or the rollback. One click, saved for the whole team. The full list stays open for the post-mortem.
Hotspots ranked by what actually broke, as confirmed by your team, not by churn. Ownership says who to involve.
Commits ranked by risk, with a confidence level that says what it rests on: Git only, deploy records, or an error trace.
A model of your repository kept between analyses: per-file history, zones, ownership. So a commit can be unusual here, not just large.
Closed Beta Access
Applications are reviewed weekly. Access is limited to 6-10 teams.
Closed Beta (Limited Places)
Free
Free while beta is open. New applications move to the waitlist when all places are filled.
We confirm details with each team before moving to paid plans.
Closed Beta
For teams where change piles up faster than one person can read it, and incidents hurt.
How to judge it: not "was the faulty commit first?" but "would this list have had me start in the right place, sooner?" An incident whose cause you already know is the best test.
You're on the waitlist
We're onboarding a small number of teams at a time, and we'll email you when a spot opens. One thing worth doing in the meantime: note a recent post-deploy incident and roughly when it happened. It is the best way to judge the result.
They start from the symptom. With a clean stack trace, Sentry or Datadog will often take you straight to the faulty line, and AI SRE agents query your code on demand. Sealens starts from your repository: it ranks the commits in the window even on a latency alert with no stack trace, and keeps what your team confirmed, tied to the files that broke.
Wiring an alert to an agent gets you a list. What takes longer is what it needs before the question: your team's verdicts, recorded as they are made and recalled when the same alert fires, what was actually running when it broke, and the same check before every release. Then someone has to maintain it.
From the first alert: the ranked list of the commits in the window, plus what was running, once your deploy records are connected. You can also see the result on a past incident. What your team concluded, and the code that has broken before, grow with each confirmed cause.
Sealens doesn't see the runtime: a provider outage, an expired certificate or a quota are out of its reach, and the confidence level says so. When no code changed in the window, it states that. When commits did change, it never claims the cause is elsewhere.
Read-only access to your history, files and metadata: it never creates commits, pull requests or branches. Repositories are connected one by one, not as an org-wide install. Hosting is on Scaleway, in Paris. One exception: readable summaries call Anthropic's Claude API (US-based) with structured analysis data only, not your raw code or diffs.
