The self-hosted Greptile alternative

Greptile is a genuinely good reviewer, and its edge is real: it builds a graph index of your whole repo and reviews with full-codebase context, which is exactly what you want on a large monorepo. We're not going to claim we out-index it. This page is for the different problem Gatekeep solves: turning review into an enforceable, auditable control, self-hosted with your own model, at a flat self-serve price.

TL;DR — who should pick which

Side-by-side comparison

Competitor behavior below reflects Greptile's own public site, pricing page, and security page as of July 2026. Sources and verification dates are listed under the table. Where Greptile is the stronger option, we say so.

Sources, each verified 2026-07-23: Greptile pricing (Starter free, 1 active developer, 50 credits/mo; Pro $30/seat/mo, 50 credits per seat, $1 per additional credit; Enterprise custom with the option to self-host in your own infrastructure, SSO/SAML, GitHub Enterprise support) — greptile.com/pricing. Self-hosting in your VPC or behind your VPN, "bring their own LLM by inserting their own base URL and keys," cloud inference on OpenAI and Anthropic, on-prem code "never leaves their servers," and SOC 2 Type II compliance — greptile.com/security. Graph index of the codebase and full-context PR review — greptile.com. Verify current terms with Greptile; their plans can change.

The governance gap

The comparison table has one row that matters more than the rest for regulated teams: merge enforcement. Here's the detail behind it.

Greptile's review lands as PR comments. Its agents assess a change's impact beyond the diff and flag issues, and you can write custom rules in plain English (source: Greptile site, as of July 2026). That's high-quality advisory review. What we can't find documented is a control that blocks the merge on a policy violation and forces a written justification before anyone overrides it. A comment can be read, resolved, or scrolled past. A gate has to be answered.

For a lot of teams, excellent advisory review is exactly what they want. For a team under SOC 2, ISO 27001, or HIPAA, "the reviewer flagged it and the author merged anyway" isn't the same as "this merge was blocked, and here's the exception, in the actor's own words, recorded immutably." That gap is the whole reason Gatekeep exists.

Gatekeep's gate locks the merge on a policy violation and won't unlock on a click. An override requires a written justification that meets a minimum length you set. The actor, target, timestamp, and reason are written to a hash-chained, append-only audit log you can export — the specific evidence an auditor asks for when they want to see how an exception was handled.

The second difference is packaging. Greptile self-hosts, but only on the Enterprise tier, as a custom annual contract. Gatekeep self-host is $499/month flat for up to 25 developers, on a card, no enterprise sales cycle, with bring-your-own-LLM on every tier — not just on the top plan. We'll be straight about the trade: you're choosing Gatekeep's gate and packaging over Greptile's deeper indexing, not getting both.

When Greptile is the better fit

Honesty is the point of this page, so here's where we'd tell you to use Greptile instead.

• Deep whole-codebase context is your top priority. Greptile builds a graph index of your entire repo and reviews with that context. On a large monorepo where cross-file reasoning is the hard part, that's its core strength, and we don't claim to match it.
• You want a vendor with SOC 2 Type II today. Greptile states it is SOC 2 Type II compliant. Gatekeep is a young product and is not SOC 2 certified; we won't pretend otherwise.
• Advisory PR comments are enough. If you don't need a forced-justification override or a per-merge audit log, Greptile's review workflow may be all the process you want.
• You're happy on the cloud product or an Enterprise contract. If your code can go to Greptile's cloud, or an annual Enterprise self-host deal fits your procurement, that path is well-trodden.

If instead you want a blocking, auditable gate, self-hosted with your own LLM on any tier, at a flat self-serve price — that's the case we built Gatekeep for.

What Gatekeep is

• Self-host, air-gap capable. One container stack in your VPC or on-prem. Zero code storage, zero telemetry, no outbound calls except to your own LLM gateway.
• Bring your own LLM, on every tier. vLLM or Ollama with open-weight models, Bedrock, Azure OpenAI, OpenAI, Anthropic, or any OpenAI-compatible endpoint. Your inference, your keys.
• A blocking merge gate with forced justification. Registers as a required status check in GitHub branch protection. Violations lock the merge; overrides need a written reason.
• A hash-chained, append-only audit log. Every review, gate decision, and override recorded and exportable — evidence your compliance program can consume.

Honest limits, stated plainly: Gatekeep is GitHub-only today (GitLab, Bitbucket, and Gitea are on the roadmap), it doesn't index a whole monorepo the way Greptile does, and it's a young product — no benchmark claims, no customer logos, and we're not SOC 2 certified ourselves. The free tier is early access. What you can rely on today is the deployment model and the gate.
