The short version

  • Each has a real cost: Decodable credit pricing rewards intermittent work and penalises always-on pipelines: a single small task running continuously costs roughly 86 US dollars a month before any parallelism.; Meltano the company behind Meltano wound down in December 2025 and the project was transferred to Matatika, a much smaller organisation, so roadmap velocity and the size of the maintenance team are now materially lower than the tool's reputation suggests.
  • They diverge on capability: Decodable covers Managed Flink, Meltano covers Singer plugin management.
  • Prices and features above were last checked on 31 August 2026.

  • A data team that wants to stop paying per-row connector fees on high-volume sources they can extract themselvesnot Decodable
  • Loading from an API that no commercial ELT vendor supports, by writing a tap with the Meltano SDKnot Decodable
  • Keeping pipeline configuration in the same Git repository and review process as the rest of the platform codenot Decodable
  • A regulated environment where extraction must run inside your own network with no data passing through a vendornot Decodable

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Decodable

  • Credit pricing rewards intermittent work and penalises always-on pipelines: a single small task running continuously costs roughly 86 US dollars a month before any parallelism.
  • Parallelism multiplies tasks, so scaling a pipeline to keep up with throughput multiplies the bill in a way that is easy to under-forecast at design time.
  • The free tier retains streams for only 24 hours, which is too short to debug an intermittent failure that surfaces days later.
  • Java and Python transformations are gated behind paid plans, so anything the SQL layer cannot express means moving off the free tier immediately.
  • The operational layer is proprietary even though Flink and Debezium are not, so migrating to self-managed Flink later means rebuilding connectors, schema handling and monitoring from scratch.

Meltano

  • The company behind Meltano wound down in December 2025 and the project was transferred to Matatika, a much smaller organisation, so roadmap velocity and the size of the maintenance team are now materially lower than the tool's reputation suggests.
  • Singer connector quality varies enormously; a tap may be maintained, abandoned, or maintained only for the subset of endpoints its original author needed, and you will not know which until a schema change breaks a load at 3am.
  • There is no managed hosting from the project itself, so someone on your team owns scheduling, secrets, retries, alerting and upgrades, which is real headcount that a per-row SaaS bill was buying for you.
  • It is command-line and YAML first with no meaningful web interface, so analysts who are not comfortable in Git and a terminal cannot maintain pipelines themselves.
  • Debugging spans three layers, the tap, Meltano itself and the target, and each has its own logging conventions, so failures often require reading Python source in a third-party connector.

Can I use Decodable for free?
Both have a free tier, so you can try either at no cost before committing.
What is Decodable best used for?
Decodable is most often used for streaming postgres change data capture into snowflake or iceberg without running debezium and kafka connect yourself, real-time enrichment and filtering of event streams before they reach an expensive warehouse, a team that already writes flink jobs but does not want to operate the cluster, checkpoint store or upgrades, replacing a fragile set of cron jobs and lambda functions that move data between operational systems. Of those, streaming postgres change data capture into snowflake or iceberg without running debezium and kafka connect yourself and real-time enrichment and filtering of event streams before they reach an expensive warehouse are not what Meltano is typically brought in for.

Answered from the vendors’ own pages

Decodable: What is a credit worth?

0.12 US dollars on On Demand and 0.10 on Enterprise. A small task consumes one credit per hour, medium two, large four.

Meltano: Is Meltano still maintained after the company shut down?

Yes. Arch, formerly Meltano, was acquired by Matatika in December 2025 and the open source project continues under their stewardship, with releases through 2026.

Decodable: Is there a free plan?

Yes, up to four concurrent tasks with 24 hour or 10 GB stream retention.

Meltano: Is there a hosted Meltano?

Not from the project. Meltano Cloud was retired, and hosting now comes from Matatika or from running the container yourself.

Decodable: Is it really Apache Flink underneath?

Yes, Flink for processing and Debezium for change data capture, both managed by Decodable.

Meltano: How does it compare on cost with Fivetran?

Meltano has no licence fee, so the comparison is your engineering time versus Fivetran's per-monthly-active-row billing. High-volume, low-complexity sources favour Meltano; long tails of fiddly SaaS APIs favour Fivetran.

Decodable: Can I run my own Flink jobs?

Yes, Java and Python jobs on paid plans; the free plan is SQL only.

Meltano: Can I use Airbyte connectors with it?

Yes, Meltano can run Airbyte source connectors through a bridge, which widens the connector pool beyond Singer taps.
