Spikelog – A simple metrics service for scripts, cron jobs, and MVPs
Hi all! I built Spikelog because I kept wanting to track simple numbers over time but every time I looked at proper observability tools, I'd bounce off the setup complexity. I wanted to make something that didn't require a lot of thinking to use. Spikelog is made to be as simple as possible: - POST a JSON with chart name + value (you can add some tags as well but I've not tested this part works yet) - Chart appears automatically - 1,000 point rolling window per chart (old data expires, no retention config) - Max 10 charts That's basically the whole product. I built it in about a day using…

In plain words
Spikelog is a lightweight metrics service for tracking simple numbers over time from scripts, cron jobs, and early-stage projects. Users POST JSON data with a chart name and value, and charts appear automatically with a 1,000-point rolling window per chart. It supports up to 10 charts with optional tags and requires minimal setup or configuration. The service is designed for developers who find traditional observability tools overly complex and need straightforward metric tracking without extensive overhead.

Log and visualize your application metrics with a simple API
Built for developers and vibe hackers. Just POST a number and see it over time. They need to know: Did the job run? Did users sign up? Did today's number go up or down? We built this public Spikelog metrics dashboard using Spikelog itself. One prompt identified the most meaningful signals across the system and automatically implemented the tracking that powers every chart you see here. If you can make an HTTP request, you can use Spikelog — cron jobs, scripts, workers, or anywhere you write code. curl -X POST https://api.spikelog.com/api/v1/ingest \ -H "X-API-Key: YOUR_API_KEY" \ -H "Content-Type: application/json" \ -d '{"chart": "Metric Name", "value": 42}' AI-Native Paste a prompt into…from spikelog.com

superlogJun 2026 · superlog.sh · ▲497Hey 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…

GraphJSON – Easily log and analyze events using ClickHouse2022 · graphjson.com · ▲128Hi HN, My name is JR and I had a need for a simple analytics solution that allowed me to store (timestamp, json) logs and run SQL over them. It was hard to find the right solution. Solutions like Mixpanel and Amplitude optimized for particular report types. Whereas solutions like Snowflake, BigQuery, etc. required a lot of setup. I built GraphJSON to fit in the middle. I strived for the ease of use of tools like Mixpanel and Amplitude, but wanted to ensure affordances were built to support use cases that big data warehouses enable. Under the hood, GraphJSON is powered by ClickHouse. This…

Talanoa▲346Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
