    Sure, we will include dynatrace and elastic in our next update. The line items are mostly based on how the product does the billing u/RabidWolfAlpha. Datadog has an SKU-based billing structure. If you visit their pricing page, they list down a lot of products, and they bill each of them separately. For example, APM and infrastructure monitoring are two separate paid products. SigNoz is based on usage-based pricing; only pay for how much data you ingest. Billing is based on how much logs, metrics and traces you ingest. There is no separate billing for APM and infrastructure monitoring. SigNoz has most features that Datadog provides, except things like network monitoring, Cloud SIEM, etc. Are you looking for any specific feature? p.s SigNoz is also open source: our github repo.

    Folks on this thread might want to check out SigNoz ( It's an open source alternative to Datadog.

    I am one of the maintainers at SigNoz. We have come across many more horror stories around Datadog billing while interacting with our users.

    We recently did a deep dive on pricing, and found some interesting insights on how it is priced compared to other products.

    Datadog's billing has two key issues:

    I am not sure when you tried OpenTelemetry, but it is decently mature now, esp. for tracing. I am a maintainer at SigNoz ( and we have good support for tracing using Otel for most of the common frameworks.

    I agree it was a bit rapidly evolving in early days, but now its much more mature.

    You can check out our docs for distributed tracing here -

    We are building SigNoz ( - an open source alternative to DataDog. We are natively based on opentelemetry and see lots of our users very interested in that.

    As mentioned in some other places in the thread, DataDog pricing is very unpredictable and high - and I think more open standards based solutions are the way forward which provides users more predictability and flexibility

    You should check out SigNoz ( - It's an open source alternative to DataDog with metrics, traces and logs in a single application. You can just self host it yourself or try the hosted version.

  • Ask HN: If we make it open source, how do we monetize it?
    2 projects | | 3 Jun 2023
    You can earn by offering a hosted version and releasing an open-source version under the GPL license, similar to Plausible [1]. This approach can help reduce competition with the hosted version.

    Alternatively, you can release the software under the MIT license and keep certain parts of the code under an enterprise license, following the PostHog model [2]. This allows you to offer an enterprise version and charge for it.

    Ultimately, the decision should be based on your target users. Small businesses may prefer the hosted version as it relieves them of hosting and maintenance responsibilities.

  • As a buyer of SaaS product, which ones do you prefer: self-hosted vs cloud, one-time payment vs subscription?
    3 projects | /r/SaaS | 20 Apr 2023
    There should be reflection on launching a self-hosted/open source and SaaS offer, for your product, though. I'd take a peek at what the teams at Bitwarden, Posthog, Metabase and Lago are doing for some inspiration of how you could consider contrasting both types of offers for the same service.

    I can't find anything quite like GA, but I often use PosthogPosthog a lot. You can add formulas, without SQL or code, into reports which give full flexibility in creating Attribution models.

    If they have a big budget and they can afford shelling out, I personally love Posthog as an analytics tools.
  • Ask HN: Who is hiring? (March 2023)
    16 projects | | 1 Mar 2023
    Remote GMT -8 to +2 | (i) Technical Writer (ii) Senior Developer | Full Time | Salaries all visible at (location-dependent) - see handbook at

    Open source, 6x rev growth last year, heading for profitability soon, well paid experienced team of 37 today, 25k customers across free + paid products, 65k developers in community, 0 outbound sales - all inbound growth. Didn't raise a 2021 overpriced round - real (potential!) upside.

    * Technical writer *

    Looking to hire a developer who loves to write. We aim for each piece we produce to be the best on the internet for that topic.

    Content marketing is huge for us - writing deep technical content is what we want! You'd be on our (small) marketing team, making a huge impact.

    Previous blogging (especially personal/interesting!) and a few years of development experience needed.

    If interested, james at and charles at for a chat.

    * Full stack developer *

    We are looking for someone to build the next generation of our analytics backbone. You'll be working on ClickHouse and Python to make sure all our queries are web scale and users are happy.

    You will (probably) help us build HogQL (our own wrapper around ClickHouse SQL), or whatever else you think makes sense to prioritize. We work in small teams of up to 6, and you'll have a lot of trust to pick what to work on.

    You need experience building high performance data systems, must be an expert at Django with deep SQL/database skills. Ideally, but optionally, you'd have worked in a high growth SaaS company / analytics product and have extensive experience with TypeScript-based React. We need someone ideally that has both worked in a very scrappy / early stage way _and_ ideally has seen a company scale.

    This work will potentially extend into providing a full warehouse to our customers. It's a chance to work on the next Snowflake, but open source and product led, working with new companies from day 1 and staying with them as they scale - so get here in the first 40 employees before we are 100x the size.

    If interested, james at + careers at and please mention you saw us on HN.
