Meteroid: Open-Source Billing Infrastructure, the Stripe Billing Alternative for SaaS

2026-01-29 | ProductHunt | Official Site | GitHub

30-Second Quick Take

What it is: An open-source tool helping SaaS companies handle billing. It's a one-stop shop for subscription management, usage-based billing, automated invoicing, and pricing experiments.

Is it worth your attention?: Absolutely. If you're building a SaaS, especially one with usage-based billing (charging by API calls or tokens), but want to avoid Stripe's 0.8% cut or Chargebee's 5-figure annual fees, Meteroid is the most cost-effective choice. It's €49/month for cloud hosting, or completely free if you self-host.

Three Questions for You

Is this for me?

Target Audience:

• SaaS founders, especially those building API or AI products
• Technical teams with the capacity to self-host and maintain infrastructure
• Companies looking to pivot from traditional subscriptions to usage-based models

Do I fit?: If you're building a product that needs to charge by usage (AI calls, API requests, compute time), you are the target user. If you just have simple monthly subscriptions, Stripe Billing is likely enough.

When would I use it?:

• Your product charges per API call → Use Meteroid
• You want to test different pricing strategies (hybrid fixed + usage) → Use Meteroid
• You want full control over your billing data without ecosystem lock-in → Use Meteroid
• You only have simple $9/$19/$49 subscription tiers → You don't need Meteroid

Is it useful?

ROI Judgment: If your monthly billing exceeds €6,000, switching from Stripe Billing to Meteroid saves €500+/year. If you have the DevOps skills to self-host, it's free. For early-stage founders, the flexibility and transparency for €49/month is a massive win.

Why you'll love it

The "Aha!" moments:

• True Open Source: Not a "pay-for-core-features" model. It's AGPL, meaning all features are available.
• Rust Performance: The metering engine is built in Rust, designed to handle massive data scales.
• No Revenue Share: A flat €49/month, regardless of how large your billing volume grows.

The "Wow" Factor:

"€49/month for the full platform — billing, metering, invoicing, insights, everything — until you hit €1M in cumulative revenue" — Meteroid Official

Real User Feedback:

Positive: "Leading open-source platform for developer teams wanting code transparency, data control, and no revenue share fees" — LedgerUp 2026 Review Potential Concern: The product just hit v1 RC, and the community is still small (785 stars), so expect some early-stage stability issues.

For Indie Hackers

Tech Stack

• Frontend: React
• Backend: Rust (Chosen for high performance, safety, and concurrency in billing)
• Database: PostgreSQL (Transactional data) + ClickHouse (Analytics)
• Message Queue: Kafka (Event streaming)
• Deployment: Docker Compose / Kubernetes Helm

Core Implementation

Meteroid integrates via a simple API to collect usage data. Once data hits the metering engine, it calculates bills based on your defined pricing models. Supported modes include:

• Traditional subscriptions (Monthly/Yearly)
• Usage-based billing (Pay-as-you-go)
• Hybrid models (Base fee + usage)
• Tiered pricing (Volume discounts)
• Grandfathering (Keeping old users on legacy pricing)

Open Source Status

• Fully Open Source: AGPL V3 license, all features open
• GitHub: meteroid-oss/meteroid
• Stars: 785 | Forks: 35
• Similar Projects: Lago (More mature but uses Ruby/Node), OpenMeter

Build vs. Buy: Building a billing system is hard. Handling edge cases like refunds, upgrades/downgrades, taxes, time zones, and currency conversion takes 2-3 engineers at least 6 months to get right.

Business Model

• Monetization: Open-source free + Cloud-hosted paid
• Pricing: €49/month (Cloud) until €1M in cumulative revenue
• Traction: Not public, but GitHub activity shows steady growth

Giant Risk

Stripe has Billing, but it's positioned as "payments with billing attached," not a specialized engine for complex usage. Meteroid targets Stripe's weak spots (complex metering, transparency, no lock-in). The risk of being crushed is low in the short term because Stripe's commission-based model prevents them from going free/open-source.

For Product Managers

Pain Point Analysis

The Problem: SaaS companies want usage-based billing, but current tools are either too expensive or too clunky.

Urgency: High. Every SaaS needs billing, and usage-based pricing is becoming the standard (adopted by 61% of SaaS companies).

User Persona

• Primary: Technical SaaS founders, DevOps engineers
• Secondary: Finance teams, Product Managers
• Scenarios: Setting pricing plans, viewing revenue dashboards, managing invoices

Feature Breakdown

Competitive Landscape

Key Takeaways

1. Visionary Pricing: €49/month up to €1M revenue is a genius move for early-stage trust.
2. True Open Source: Building a community by not gatekeeping core features.
3. Rust Selection: Playing the performance card for high-frequency metering scenarios.

For Tech Bloggers

Founder Story

Gaspard Boursin (CEO) and Donatien Dubois were high school friends in Lille. After school, Gaspard became an IBM engineer building predictive maintenance for aerospace, while Donatien studied finance at EDHEC and spent 6 years in banking audit.

Two years ago, they got tired of SaaS billing tools—Stripe was too expensive at scale, professional platforms were too gatekept, and building their own was a distraction. So, they built Meteroid.

With Teake (Netherlands) and Artur (Ukraine), they operate as a truly international remote team.

Discussion Angles

• Open Source vs. Commercial: Is AGPL open enough? Will they pull a bait-and-switch later?
• The Rust Bet: Is Rust overkill for billing, or is the performance necessary for the AI era?
• Challenging Stripe: Can a small team actually shake up a payment giant?

Hype Metrics

• PH Rank: 212 votes (2026-01-29)
• GitHub: 785 stars, 35 forks
• Dev Cycle: 2 years
• Version: v1 RC (Freshly released)

For Early Adopters

Pricing Analysis

Hidden Costs: Self-hosting requires managing PostgreSQL, ClickHouse, and Kafka. Expect €50-100/month in cloud infrastructure costs.

Getting Started

• Time to value: 1-2 days (Cloud), 1 week (Self-hosted)
• Learning Curve: Moderate
• Steps:
  1. Sign up for Cloud or git clone the repo
  2. Configure your product catalog and pricing
  3. Integrate the API into your app
  4. Test the billing flow
  5. Go live

The Catch

1. v1 RC Stage: It's new; expect some bugs.
2. Docs: Could be more comprehensive.
3. Community: Small for now; you might need to dive into the source code for complex issues.

Security & Privacy

• Data: Yours if self-hosted; on their servers if Cloud.
• Privacy: GDPR compliant (European team).

Alternatives

For Investors

Market Analysis

• Market Size: Subscription billing $8.47B (2025) → $37.36B (2035)
• Growth: 16% CAGR
• Drivers:
  • AI explosion requiring token/call-based billing
  • SaaS shift to usage-based pricing (61% adoption rate)
  • Gartner predicts 70% of enterprises will favor usage-based billing by 2026

Competitive Landscape

Timing

• Why now?: AI needs granular billing; SaaS 3.0 is moving away from flat subscriptions; Stripe's revenue share is becoming a "success tax."
• Tech Maturity: Rust ecosystem is ready for high-performance metering.

Team & Funding

• Founders: Strong mix of IBM engineering and high-level finance audit.
• Status: Likely bootstrapped or small angel round; 2 years of dev to reach v1 RC.

Conclusion

Meteroid is the "SQLite moment" for SaaS billing—shattering monopolies with open-source transparency.
