The short version
- Each has a real cost: Comet ML the free cloud tier caps data at 25,000 spans a month with 60 day retention; Meilisearch not built for log analytics or aggregation-heavy workloads, which is where Elasticsearch remains the answer
- They diverge on capability: Comet ML covers Experiment tracking, Meilisearch covers Typo tolerance.

Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Comet ML
- The free cloud tier caps data at 25,000 spans a month with 60 day retention
- Retention stays at 60 days even on the paid Pro plan, and extending it is a $29 per 100k spans add on
- Overage on Pro is $5 per additional 100,000 spans
- The free MLOps tier is a single user with 100 GB of storage and training hours governed by a fair usage policy
- Pro MLOps is $19 per user per month and caps the team at 10 users
Meilisearch
- Not built for log analytics or aggregation-heavy workloads, which is where Elasticsearch remains the answer
- Scaling across many nodes is less mature than the older engines it competes with
- Memory use grows with index size, and large datasets need real capacity planning

Answered from the vendors’ own pages
Comet ML: Does Comet.ml offer a free plan?
Yes, Comet.ml offers free tiers for both Opik (cloud observability) and MLOps platforms. Free Cloud Opik includes up to 10 team members and 25,000 spans/month. Free MLOps tier is limited to 1 user.
SourceMeilisearch: Is Meilisearch free?
The engine is open source and free to self-host. Meilisearch Cloud is a paid managed service.
Comet ML: How many team members can use the free Comet.ml tier?
Free Cloud supports up to 10 team members. The Pro Cloud plan supports up to 50 team members at $19/month.
SourceMeilisearch: Meilisearch or Elasticsearch?
Meilisearch is far simpler for application search and works well by default. Elasticsearch is the choice when you also need log analytics and heavy aggregations.
Comet ML: What is a span in Comet.ml pricing?
A span represents a single tracked operation such as model requests or function calls. Free Cloud tier includes 25,000 spans per month.
SourceMeilisearch: Does it handle typos automatically?
Yes. Typo tolerance is on by default rather than something you configure.
Comet ML: Does Comet.ml offer academic pricing?
Yes, a free Pro plan is available for academic users; verification is required via signup.
