Show HN: Superlog (YC P26) – Observability that installs itself and fixes bugs

https://superlog.sh/
14•Magnanten•59m ago
Hey HN, we’re Nico and Arseniy, co-founders of Superlog (https://superlog.sh). We're building a self-installing, self healing observability tool meant not to be opened. It has a wizard that daily sets up proper logging and an agent that investigates errors and opens PRs.

Super short demo: https://www.youtube.com/watch?v=xFhU9Mk247M.

In our earlier startups, we tried Sentry, Datadog, Grafana, Dash0, and nothing was good enough. Proper telemetry and alerting still requires a ton of manual setup. We struggled with adding good logs, so debugging was tough, especially as codebases grow at a faster pace. Meanwhile, the Datadog/Dash0 bill kept climbing, and we still spent engineering hours to learn, configure, and maintain our observability tooling.

With Sentry, we found ourselves flooded by a stream of alerts into our Slack channel, most were duplicates or lacked context, so alert fatigue/constant interrupts were a real pain. The #ops notification is consistently the worst feeling on a Saturday morning

We’ve seen too many times servers run out of memory and disk, and three AWS metrics giving us three different values. Half of the graphs on dashboards are normally empty or outdated, and manually clicking through UIs, especially when the team is small, seems like a huge waste of time.

At some point we realized that solving this problem would be more valuable than the things we had been working on, and we had the expertise to do it, since Arseniy had spent years at Datadog, getting paged during the night to debug production incidents. So we decided to build a platform that would just work: agent-first, MCP-native, zero-setup.

Here’s how Superlog works: we have a wizard that scans your repo, and automatically instruments it with well-structured logs, traces and metrics via OpenTelemetry. We make sure to highlight main failure modes, endpoint performance, usage per tenant, and LLM/upstream cost (by callsite, tenant and model).

Errors get fingerprinted and grouped into incidents, so you see one issue, not a thousand duplicates. When you get a notification from Superlog, you see a clear failure summary, its inferred severity and impact upfront.

Then the agent investigates and tries to solve the issue. If it has enough context, it produces a concise and tested PR. If it doesn't, it posts its findings for the investigating team, and automatically pulls in the engineers that could contribute more context based on documentation, previous investigations and Slack threads.

Either way the output is one clean PR per incident, posted in Slack, that you can merge, ignore, or open as a Claude Code session and modify.

Three things we think are different from other observability vendors:

(1) We solve the setup pain. The wizard will instrument everything with native OTel SDKs, respecting the semantic conventions, with proper service and environment tagging. We’re also working on native automatic dashboards and alerts, so that you can see what’s going on in a glance and don’t miss subtle failure modes.

(2) Our telemetry doesn’t decay. The wizard runs daily, and keeps adding logs, alerts and dashboards where it’s needed. You don't have to remember to instrument new features. The next time something breaks, the data you need to debug it is already there.

(3) Our goal is to solve alert fatigue. We use agents to merge similar errors and refine the summaries, giving you relevant information upfront. We have a custom evaluation setup that makes sure that our summaries are dense and correct, and severity and impact is on point. We also give you confidence scores for every LLM-enhanced metric so that wrong guesses don’t get boosted.

Important: superlog telemetry is vendor-neutral, so you keep all the logs/metrics/traces we install. Pricing is on the site. We're early, so expect rough edges and please tell us when you find them.

You can try it at https://superlog.sh. We'd love to hear what you're using today, what's broken about it, and whether the "one mergeable PR per incident" model sounds useful or terrifying. Especially keen to hear from folks running integration-heavy products, anyone who's rolled their own observability, and anyone who has tried Sentry / Datadog MCPs and given up. Comments and feedback welcome!

There's very few startups that I look at these days and don't think to myself, "I could just write a Claude skill for that". This one seems pretty cool. Congrats on launch

Love the concept! Some feedback: I went to sign up to give it a go, but the set up process left me feeling a bit untrusting - so I backed out for now. I'd prefer more explanation about what to expect, what I will get, how it is safe, etc before asking me to run a prompt.
signalbright•1m ago
Thank you! Very good point.

Right now, the prompt will enumerate all the services and install the OpenTelemetry SDK (https://opentelemetry.io/) in each service.

Then for every service, the skill will make sure that:

- Every time something breaks and an operator needs to take a look, there's an error log - All important steps in a process emit info/debug logs (so that an issue can be investigated) - Operations are covered with spans with relevant attributes. - Cost (LLM tokens), API performance (latency/RED), tenant activity (cost/usage per tenant) are covered by metrics so that you can use Superlog MCP to build cool dashboards.

For most common stacks like NextJS, FastAPI, React Native/Expo etc. we have a custom skill that explains the best practices for this specific technology. For all the other stacks we ask the agent to use general best practices.

We have evals for all custom skills where we start from a starter project, run the agent with the skill and use LLM-as-a-judge to compare it to a human-written 'golden patch'.

In general, we try to:

- minimize diff, so that the instrumentation is easy to review - make small chunks of additive diffs vs huge indents / moving logic around - minimize new dependencies - use well-supported and audited OTel SDKs vs custom libs

You can read the skills here: https://github.com/superloglabs/skills.

I'll make sure to add this to our landing and print this out as the agent writes the code!

Thank you for the feedback!

I would love to try it but I got stuck when it asked for Slack since I dont use that.
