The short version

  • Each has a real cost: 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.; ToolJet free and Pro tiers cap end users at 50, which may be too low for apps needing broad internal distribution.
  • They diverge on capability: Meltano covers Singer plugin management, ToolJet covers Drag-and-drop app builder.
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

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

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.

ToolJet

  • Free and Pro tiers cap end users at 50, which may be too low for apps needing broad internal distribution.
  • Enterprise pricing starts at a steep $3,000/month, a large jump from the $199/month Team plan.
  • AI credits reset monthly and do not roll over, penalizing uneven month-to-month usage.
  • Smaller integration and community ecosystem than more established players like Retool.

Answered from the vendors’ own pages

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.

ToolJet: What happens if I run out of AI credits?

Users can continue using all other ToolJet features as normal and can contact support to purchase additional AI credits when the monthly allotment runs out.

Source
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.

ToolJet: Do unused AI credits roll over?

No, AI credits reset every month and unused credits do not carry over, which ToolJet says helps maintain consistent service quality.

Source
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.

ToolJet: Can ToolJet be deployed on-premise?

Yes, both the community and enterprise editions support on-premise and air-gapped deployments, typically completed in under 30 minutes.

Source
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.

ToolJet: Is there a free trial for paid plans?

ToolJet offers a 14-day free trial for both its business and enterprise editions.
