Questions about alternatives to Splunk Agent Observability
What is the best open source alternative to Splunk Agent Observability?
By GitHub stars it is Langfuse, with 37,399 stars and a commit on 13 Nov. Choose Langfuse when you want MIT-licensed tracing, prompt management and evals that you can self-host for free. Next come Helicone (6,280 stars) and AgentOps (5,954 stars).
Is there a free alternative to Splunk Agent Observability?
Yes. The code of all 5 is public under MIT or Apache 2.0, so you can use them with no licence fee. Running one yourself costs the server and your time to look after it, and some makers also sell a hosted plan.
How do I choose between them?
Start from the job you use Splunk Agent Observability for. Choose AgentOps when you want MIT-licensed agent tracing with session replays and cost tracking, without adopting the Splunk Observability Cloud stack. Choose Future AGI when you want agent tracing and evals with a free plan and a self-hosted option outside Splunk Observability Cloud.
Which Splunk Agent Observability alternatives can I host on my own server?
3 of the 5: Langfuse, Helicone and Latitude. Each tool's page says what it needs to run.
Which ones are still being worked on?
4 of the 5 we track had a commit in the last 30 days, among them Langfuse, Helicone, Latitude and Future AGI. The quietest is AgentOps, last changed on 25 Jun. A recent commit shows the project is kept up, not that it will stay that way.
What licences do they use?
MIT (3), Apache 2.0 (2). MIT, BSD and Apache let you change and reuse the code freely.
What do I lose by leaving Splunk Agent Observability?
The hosting. Splunk Agent Observability's maker runs the servers for you; with an open source tool the updates, backups, security fixes and support are yours, unless you take the maker's hosted plan. Features differ too, so check what each one imports and exports before you move your data.
